Frequently Asked Questions - HCC 360P2 Dantherm

How often should I replace the filters in the HCC 360P2?

Filters should be checked every 6 months and replaced at least once a year or when the filter alarm activates. If you use optional ePM1 filters, they may need more frequent replacement depending on air quality.

Can I install the unit horizontally or vertically?

Yes, the HCC 360P2 can be mounted either horizontally (under ceiling) or vertically (on wall). The included bracket ensures a 1° tilt toward the drain side. Always leave sufficient service space as specified in the manual.

What is the purpose of the bypass damper?

The motorized bypass damper overrides the heat exchanger, allowing cool outside air to bypass the heat exchanger. This is used in warm summer conditions to reduce indoor temperature when the inside temperature exceeds an upper limit.

How do I reset the filter timer?

Press and hold the filter reset button on the unit for 5 seconds until the LED stops flashing. On the wireless remote, press and hold the center button for 10 seconds. This can also be done via the PC Tool or smartphone app.

What does error code E12 mean?

Error E12 indicates an overheating condition where any internal sensor exceeds +70°C. This may be caused by fire, blocked airflow, or a faulty preheater. Reset the alarm after resolving the issue by pressing the alarm button or power cycling the unit.

Can I control the unit remotely?

Yes, you can use the Dantherm smartphone app (iOS/Android) if the unit is connected to the same Wi-Fi network. Alternatively, use the wired remote control (HCP10/11) or the wireless handheld remote (HRC3).

What is the maximum outdoor temperature for operation without a preheater?

Without a preheater, the unit can operate in outdoor temperatures from -12°C to +45°C. If the temperature drops below -5°C, a preheater is recommended to ensure balanced ventilation and reduce defrost cycles.

How do I clean the heat exchanger?

Every two years, remove the heat exchanger by turning the four locks. Clean it with a soft brush and vacuum cleaner at all inlets. For heavy dirt, use soapy water and rinse thoroughly before reinstalling.

What is the difference between mode A and mode B?

Mode A and B define the duct connection orientation. In mode A, supply air is on the right side; in mode B, it is on the left. You can swap between modes by sliding a switch on the PCB and repositioning the drain hose and sensors accordingly.

Is the unit compatible with third-party building management systems (BMS)?

Yes, the unit supports Modbus TCP/IP over its Ethernet port. This allows integration with BMS for remote monitoring and control. Note that the RS485 port is reserved for Dantherm accessories only.

Components description

Introduction	This section describes the individual components which are included in the HCC 260/360 unit. Please use the illustration on page 6 for reference.
Cabinet	Cabinet outer parts are made of aluzink sheet metal. The inner part is one moulded polystyrene block. If adding accessory or exchanging parts, access to all parts are available, just by removing the front cover and drip tray.The cabinet is internal sound and heat insulated, with fire retardant polystyrene foam. The unit's cabinet is designed for mounting in 12^ - 40^ C ambient temperature
Heat exchanger	The counter flow heat exchanger absorbs the heat energy from extract air and moves this heat energy to the ingoing supply air, resulting in domestic ventilation with low heat loss.
Fans	The supply fan supplies fresh outdoor air through the unit's heat exchanger to the ducts, where it's distributed to bedrooms, living rooms and possibly sauna or steam bath.The extract air fan draws used, moistened and polluted air from house, through the unit and heat exchanger, where the heat is transferred to supply air.
Bypass damper	The motorized bypass damper overrides the heat exchanger functionality. This is used in warm summer conditions, where colder outside air can be used for reducing inside temperature, when inside temperature exceeds an upper temperature limit.
Controller	The unit's main controller is named main PCB. It electrically connects all electrical and electronic parts and various accessory components.
Temperature sensor	Units are fitted with 4 temperature sensors that continuously monitor the temperature changes on 4 sides of heat exchanger, i.e. in outdoor air, in supply air, in extract air and in exhaust air.
Humidity sensor	The HCC 260 P1 unit, is not default fitted with a RH sensor. RH sensor is available as an accessory.HCC 360 P2 and E1 units are fitted with an RH sensor in the extract duct.The humidity sensor will continuously monitor the quality of the extract air, and adjust the air flow level accordingly. This operation is named demand mode.If an HRC remote control is connected, the level will be shown in the display using 3 level icon.Using demand mode will result in the correct level of ventilation with lowest possible electrical power consumption.
Filters	The unit is fitted with two ISO Coarse class cassette filters. These filters protect the heat exchanger and improve the indoor climate by removing dust and particles in both airflows.As alternative/accessory, an ePM1 class filter can be obtained. If ePM1 is used, then it is always placed in the supply air, removing even smaller particles.
Water drainage	The unit is fitted with 2 pcs. spigot connections for draining condensed water. It is mandatory to fit the spigot next to the T4 with a hose, discharging the condensed water to a sever.Correct drainage is shown on the connection label placed on the unit. The remaining unused drain is to be blocked with the enclosed cap.
Hanging rail	The unit is delivered with hanging rail.

Accessory

Introduction	The unit is delivered from factory, without any accessories mounted. These are to be installed prior to initial unit installation or alternative after commissioning, if further functionality is requested. The detailed installation of one or more accessories, is illustrated on the leaflet following each accessory.
Electric preheating	The unit can be fitted with an electrical preheating element that preheats the incoming air. The preheater increases the outside air temperature going into the heat exchanger, and thereby reduces the risk of ice in the heat exchanger in very cold conditions. The preheater is an external enclosure, connected and controlled by the HCC 260/360 controller.
Hand held Remote control	For controlling HCC 260/360 units, Dantherm recommends using remote control, designed for this range of units.	Fig. 5
Wired Remote Control (HCP 10/11)	A wired remote control (HCP 10/11) without display can be connected to the unit as an alternative to the hand held remote control.	Fig. 6
Accessory control (HAC 2)	Connect a number of additional accessories to the HCC 260/360 unit via an accessory controller: HAC 2.	Fig. 7
VOC and humidity sensors	HCC 260/360 can be fitted with Humidity (RH%) (if not already included as standard) and/or VOC (organic chemicals) sensors. These sensors will continuously monitor the extract air, and adjust the air flow level accordingly. This will result in adequate level of ventilation, with lowest possible electrical power consumption. If a remote control is connected, the sensor level will be shown in the display using 3 level icon.	Fig. 8
Filters	Replacement of filters in sets of 2 ISO Coarse filters or 1 ISO Coarse plus 1 ePM1 (pollen) filter.

System operation strategy

Introduction	This section describes the operation strategy in various conditions. For a user specific running operation see page 26.
Defrost	In cold conditions where T1 is below -4°C and exhaust T4 is <+8°C the condensed water could built up as ice in the heat exchanger, blocking the air path and eventually destroying the heat exchanger.In order to prevent this sequence is initiated:The supply fan speed will decrease with 3 rpm/second until minimum RPM is reached.After 10 seconds at this speed the supply fan will stop completely, while the ongoing exhaust fan is supplying warmer air into the heat exchanger component, to remove any potential ice.When T4 yet again is>+8°C the supply fan will start at minimum RPM, and then increase speed with 3 rpm/second until the original required speed is regained.If T4 becomes <+2°C during the speed increase cycle, the supply fan will decrease speed again.If T1<= -13°C for more than 4 minutes and 25 seconds, even with defrost mode active, the unit will stop all operation for 30 minutes, and reattempt previous operation condition. If electrical preheat is present, this total off mode is disabled.The defrost operation will create an under pressure inside the house, so if fireplace mode is enabled, and defrost is necessary; the unit will stop all operation in 4 hours instead. Set-points cannot be changed.When defrost is active any connected remote control will show dEF in the display, and when defrost has shut all off, the display will flash the T1 temperature
Preheat (Accessory)	If the preheater is installed, the unit will add electrical heat to the incoming outdoor air, in order to increase the temperature of outdoor air entering the heat exchanger and thereby reduce or eliminate the possibility of going into defrost mode and to ensure balanced operation as long as possible.Preheater can be "master" enabled/disabled on the wireless remote control in installer modePreheat is applied before the T1 sensor.If outside temperature is <+3°C or supply air is <+16,5°C the preheater will switch on with 10% power.The power will increase/decrease 10% for each 60 seconds depending on the T1 or T2 temperature.Temperature set-points are fixed.

Installation

General location requirements

Introduction

The HCC 260/360 must fulfil all of the previous consideration prior to starting any installation process.

Location and duct connections

The following should be considered selecting an appropriate location for installation:

1. The HCC 260/360 units, is designed to be mounted in dry surroundings, with temperatures >12°C like in utility rooms or similar heated rooms.
2. The HCC 260/360 can be mounted vertically or horizontally. Please ensure that the ceiling or walls structure is adequate to withstand the additional weight of the unit.
3. The air flow direction can be electronically swapped, providing ability to route the connected ducts, either to the right or to the left. See more about swapping at page 16.
4. It is mandatory to tilt the HCC 260/360 minimum 1° towards the drain. The enclosed bracket provides this requirement, in case of horizontal ceiling.

Reserve additional space

The HCC 260/360 is designed for hidden installation. It is very important to leave additional space:

• Adequate space for exchanging the unit if needed, including turning the unit into its bracket and up, if mounting underneath the ceiling.
• External preheater (accessory), which is mounted external into the duct system on the T1 incoming outside air, minimum 320 mm from the unit.
• Additional space, in order to inspect and test any drainage hose, also if no preheater is installed..

This applies also for after sales situations, where the unit is to be dismounted completely for service. Any warranty claim will not be acknowledge if these above requirements are not fulfilled.

See min. measurements on page 13.

Service space, ceiling

If installing the unit underneath the ceiling, please reserve space for the tilting up/down, and additional space, if electrical preheater is installed.

Wall mounting

Please follow this procedure to install the HCC 260/360 vertical onto a wall.

Step Action Illustration

1	Drill two holes for the bracket, fulfilling all dimension requirements shown in the section “General location requirements” on page 12.
2	Mount the bracket with appropriate screws
3 Lift the unit onto the bracket
4	Drill and mount two appropriate screws in the lower unit bracket
5	Connect ducts according illustration at page 15 IMPORTANT: the T1 and T4 outside air ducts, must ALWAYS be routed to the duct connections in the bottom
6	Connect ducts and drain hose.

Under ceiling installation

Please follow this below procedure for ceiling installation

Step Action Illustration

1 The HCC 260/360 should always tilt minimum 1° towards the drain side(T4). This is achieved when using the enclosed bracket, placed at T4 end of unit. Drill two holes and mount the bracket into the ceiling configuration setup (see page 17) Please allow minimum 320 mm to the ceiling edge, in order to have room for turning the unit in step 2.
2 Lift the unit onto the bracket hanging freely as shown
3 Turn the unit towards the ceiling, and secure it with two screws
4 Connect ducts and drain hose.

Connect duct system

Connect ducts (specification according local regulations), with spigot connection only.

WARNING: NEVER screw any spigot for ducts, directly onto the sheet metal of the unit.

Fig. 18

Insulate the ducts according local requirements, taking the installation surrounding temperature into consideration.

Secure ducts

Make sure that all ducts are well attached and secure, and ALWAYS fixed securely to the ceiling or wall with brackets

Fig. 19

Drainage consideration

It is mandatory in any HCC 260/360 installation to connect a water drain hose to the unit, because the humidity from the extract air condensates to water drops when cooled in the heat exchanger.

This water is harmful to its surrounding if not managed correctly. The installation thus needs a condensate water drain hose connected with a decline of minimum 10 Promille (1 cm/meter) away from the unit and the hose must NEVER exceed the level of the lower sheet metal plate.

Correct installation

The drain hose has a correct and steady fall towards the sewer.

Faulty installation

The drain hose must never be raised above the bottom plate!

Fig. 20

Condensate drainage

After guiding the hose downwards to a drain, it needs a closing loop. This will block air from escaping through the hose. Please make either a complete closed loop, or a siphon loop on the hose as illustrated, and make sure it has a minimum height of 100 mm. Fill the siphon/loop with min. 0,5 l. water before connecting the hose to the unit.

Fig. 21

Connecting additional equipment

WARNING

Connecting additional equipment is to be carried out by qualified personnel only. Always disconnect the power by removing the 230V plug from the socket, before opening the unit!

Access to connections

The integrated controller has various options to connect additional external equipment. To gain access to the controller, please open the print cover (A) of the unit, by turning it all the way around as shown in fig. 22.

The unit will be accessible for the smartphone app (IOS and Android), if your device is connected to the same network via WIFI.

IP adress allocation status	Description
Dynamic IP If the unit	is connected to a router with built-in DHCP server it will fetch the IP address itself from the router when the unit starts up.
Static IP Using PC Tool	it is possible to allocate a static IP address to the unit, which is necessary for example in order to perform checks on HCC 260/360 via smartphone app when outside the LAN's range. This will also require setup of the home's WAN address as well as allocating a port on the router.

MODBUS

MODBUS:

MODBUS RTU is only for internal communication between unit (UVC print) and Dantherm accessories (HAC, FPC, or HCP11)

Connected via RS485 port

Important! External BMS can not be connected as a Modbus RTU via RS485 port, nor via Dantherm accesso-ries. (HAC, FPC, or HCP11)

Modbus TCP/IP

The controllers in the Dantherm ventilation units has the possibility to communicate Modbus TCP/IP over the Ethernet port. This is used for Building Management Systems (BMS) or communication with smartphone apps.

Antenna

External antenna can be connected here, to gain higher coverage area.

Dig. input

The unit is fitted with 2 overrule inputs, also called digital inputs. These inputs can be used for selecting other fan speed level or activating alarms.

As default the digital input are setup to:

• Dig. input 1: Ventilation step 2
• Dig. input 2: Ventilation step 4

How it works (example to the right):

• Switch DI1 between pin 2 & 4 will activate input 1
• Switch DI2 between pin 3 & 4 will activate input 2

Dig. input can be used for:

• Ventilation steps from 0 - 4
- Safety shutdown

Initial calibration

Introduction	After the installation the unit need to be calibrated to adapt any specific duct system. This is done by connecting a computer with MS Windows, to the USB hidden under a black rubber ceiling, on the front cover, and start up the PC Tool software, specific for this unit type..
Connect power	The unit is fitted with a 230V Schuko plug. NEVER cut away this plug. The unit needs to have an easy disconnecting possibility., as it needs to be rebooted when doing a firmware upgrade, as well as being disconnected when connecting additional connections. Connect the plug into an 230V socket with earth.
Connect USB	Locate the black rubber bushing, and remove it, to be able to connect the enclosed USB cable, between the unit and your computer.
Calibration	Please follow this procedure to calibrate the unit:
	No Action Illustration
	1	Make sure the unit is in correct operation mode (A or B) according the duct connection, and assure that correct label is placed on the unit .See more at page 16
	2	Locate the air flow chart placed on the front cover of the HCC 260/360. Based on the required air volume for each specific installation, its possible to read out the corresponding pressure drop over the heat exchanger.
	3	Connect the ΔPa meter across the supply air path, as shown. This example is based on the unit being in operation mode A. Use a football needle pin, punch this all the way through the rubber ceiling pad. When removing the pin, the rubber will close the hole.Needle:
	4	Adjust the supply fan speed, according the guide in the PC Tool on your computer. The goal is to adjust the fan until the ΔPa meter shows the pressure drop value that was read in point no 2

5	Move the ΔPa meter across theextractair path as shown. This example is based on the unit being in operationmode A.
6	Adjust theextractfan speed, according the guide in the PC Tool on your computer. The goal is to adjust the fan until the ΔPa meter shows the pressure drop value that was read in point no 2,deducteda few percent,in order to create a small under pressure inside the house.
7	Disconnect the ΔPa meter, as well as the computer. Adjust the balancing of the valves in every room in order to make sure that the desired air flow rate can be supplied in every room.Check the nominal air flow rates based on earlier instructions in this procedure, as radical adjustments (balancing) will influence the nominal air flow rates.

Operation (user)

Overall ventilation functions

Introduction

Never switch off the main power to shut down the ventilation. This could ultimately result in condensate water dripping from air inlets.

The HCC260/360 unit is able to operate in the ventilation and override modes mentioned in this section. Please be aware, that the different operation modes cannot be activated via the unit itself, but have to be activated via an additional remote control (HCP 10/11 or HRC3) or via the Dantherm Smartphone app.

Ventilation modes

The units can ventilate your home in three different main operation modes. The modes are selectable according personal needs, taking in mind that national rules and regulations, can state a minimum ventilation requirement. Auto mode requires an accessory sensor

Mode Description
Manual In manual operation, the unit will run in the required fan speed at all times. Fan speed 4 is 130 % boost mode. Deactivates automatically after 4 hours Fan speed 3 is nominal fan speed, defined as 100 % Fan speed 2 is 70 % of speed 3 Fan speed 1 is 49 % of speed 3 Fan speed 0 is fan stop. Deactivates automatically after 4 hours.
Week timer Timer controlled operation mode sets the fan speed according a week time table. The controller has 10 fixed and 1 custom timer. Select a fixed time table that cover your requirements or create a custom timer, in the PC Tool. Appendix A - “Week program specification” on page 41 shows in details, the week programs layout
Demand (RH or VOC sensor needed)	In auto mode (demand), the unit will automatically adjust the ventilation level, to comply with the ventilation needs, measured in the outgoing air by VOC and/or RH% sensors. This operation mode is only possible if the unit is fitted with VOC and/or RH% sensor.

Override operation

On top of the above main ventilation modes, the user can select some override modes for various purposes. These overrides will disable automatically depending on time or temperature.

Overrides Description
Fan boost 130%	boost in 4 hours.
Summer mode	Supply fan off, extract fan still running, and colder air will flow through any open window. This reduces inside temperature in summer times, with half energy consumption.
Bypass (accessory, if not standard equipment)	Both fans running, but no heat recovery. This will automatically supply colder outside air, that reduces inside temperature in summer times.
Fireplace booster	7 min. with extract fan reduced to 50% This creates an overpressure enhancing the chimney function, when lighting a fireplace
Night mode Sets	the fan to speed 1 at night regardless of any other mode. Start and end time can be set from the remote control
Away mode In Away mode, the unit will run same fan speed as manual fan speed 1. After 28 days or manual disabling of Away mode the unit will run week program mode.

Maintenance and care

Preventative maintenance

Introduction

To keep the unit into specifications, preventive maintenance has to be carried out, with specific intervals to avoid breakdown, inefficient operation and to maximize the expected lifetime, of 10 years or more.

It is important to notice, that intervals between filter maintenance can vary depending on the specific environment. Moving parts are wearing parts, that needs replacements when worn down, dependent on the specific environment.

The factory warranty is only valid if documented preventive maintenance has been carried out. The documentation could be in form of a written log.

WARNING

- Turn off the power supply before applying any work on the unit!

- Only trained and certified technicians are allowed to service the fans. Users are allowed to changes filters only.

- Make sure that all work is finished and the front cover plate is fully mounted before turning on the power supply again.

Scope of maintenance

The following parts needs preventive maintenance:

Service interval Task To be carried out by:
6 month Filter check.	Change if required User
1 year	Filter replacement User
	External condensate discharge Trained engineer
2 years	Heat exchanger Trained engineer
	Fans Trained engineer
	Drip tray/internal discharge Trained engineer
	Internal air ducts Trained engineer

Replace filters (1 year)

Check or replace filters when the filter alarm sounds, and flashes on the remote control. Always reset the filter timer after a filter replacement. See the remote control manual for more information.

Filter intervals can be adjusted to adapt pollution level in the house, and outdoor air particle content. See how in "User Right" on page 27

Filters must, however, be checked every six months. Dantherm always recommends replacing filters at least once a year. When checking the filters, clean the unit externally around the filter openings with a damp cloth, to maintain good hygiene.

The filters are located behind the small lids, on the front panel

Fig. 25

Drain and hose (1 year)

Drain and hose must be checked every year.

Check that the hose is secured properly to the unit, and that there is water in the water trap. Check that the hose is not wrinkled and that there is a minimum gradient of 1% from the unit to the drain. If the hose is routed to different surrounding temperatures, make sure the hose is protected against frost damages.

Unit dripray (2 year)

Ensure that the condensate drain is not blocked in the drip tray. Clean the drip tray with soapy water and a brush or cloth every other year, to ensure good hygiene inside the unit. Please follow this procedure to clean the drip tray:

Step Action Illustration
1	Disconnect the 230V AC power supply, and remove the unit cover.See “Fig. 22” on page 21
2	Remove the drainage hoseand turn all shown locks 90°
3	Gently remove the drip tray.Please be aware, that if theunit is underneath the ceiling, it can contain a smallamount of water.
4	Clean and re-insert the drip tray (please check fans according below if needed, prior to inserting the drip tray)
5	Re-assemble the unit. Check if one water exit is connected, and the opposite drip trayspigot is blocked.

Fan

(2 year)

Clean the fan blades every other year using compressed air or a brush. Each fan blade should be clean in order to keep the fan balanced. Gently spin the fans and listen for bearing noise. If so the fan are worn out, and needs to be replaced.

WARNING: Be careful not to remove the metal balancing pieces mounted on the fan blades.

Trouble shooting

Introduction	This section shows how to acknowledge and understand possible operation errors. For a proper error search, Dantherm strongly recommends to have a remote control connected and operative with the unit.
Error signalling	Any possible error will be displayed on:
	Device Signal
	Unit Acoustic buzzer	signal from the main PCB. Connect a remote or PC Tool, in order to get the specific error shown.
		LED for filter reset
	Handheld remote control	Acoustic buzzer signal as well as displaying a specific error code.
	Wired remote control (HCP 10/11)	Acoustic buzzer signal and flashing LED. The number of flashes corresponds to an error code, followed by a 5 second break. See Error list.
	PC Tool Displaying error number, as well as being able to log specific operations, over a longer time span.
	Smartphone APP Displaying a specific error code.
Error list	Errors shown on the display, is a three digit information. F. ex. "E12" means error number 12.
	How to read the error list:
	Column Description Code Meaning
