Frequently Asked Questions - HRW 20 Mono D Thermex

How do I reset the filter replacement indicator?

Simultaneously press the Speed, Mode, and Boost buttons. Then press the sequence Speed, Speed, Mode, Mode, Boost, Boost. The red FILTER LED will flash briefly to confirm reset.

How do I set the number of devices controlled by the remote?

Enter programming mode by pressing Speed, Mode, Boost together. Then press Speed to enter device count setting. Use Speed to select Single (LED1), Even (LED2), or Odd (LED3). Confirm with Boost.

What are the different operating modes?

The modes are: Recovery (heat recovery between exhaust and supply air), Ventilation (balanced supply and exhaust without heat recovery), and Extraction (all units extract air from the room).

How do I connect environmental sensors?

Sensors (temperature, humidity, smoke) connect to remote inputs #1, #2, #3 on the remote control PCB using clean On/Off contacts. Each input triggers a specific mode at maximum speed.

What power supply is required for the HRW 20 Mono D?

The unit requires a 220-240 V, 50/60 Hz mains supply. For remote control, use an optional power supply like PS24W (up to 4 units) or PS36W/PS36WDIN (up to 6 units).

Can I control multiple units with one remote?

Yes, one remote control can manage up to 6 units. You must set the correct number of units (Single, Even, or Odd) in programming mode to ensure proper airflow balance.

How do I adjust the fan speed?

Press the Speed button repeatedly to cycle through speeds: Standby (0), Minimum (1), Average (2), High (3), Maximum (4). Corresponding LEDs indicate the active speed.

What is the Boost function?

Pressing the Boost button activates maximum speed for all connected units. Press again to deactivate. The Boost LED lights up when active.

How often should I replace the filters?

Filter replacement intervals are programmable: 90, 180, or 365 days. The default is set via programming mode. The red FILTER LED lights up when replacement is due.

Is the HRW 20 Mono D safe for use around children?

Yes, children aged 8 years and above can use it under supervision. However, cleaning and maintenance should not be performed by children unless supervised.

Remote Control Control Panel

Fig. 1

The appliance is controlled via wired Remote Control.

The Remote Control manages from 1 to 6 devices. The Control panel is equipped with the following controls (fig.1):

Buttons:

Ⓐ = button SPEED;
⑧ = button MODE;
© = button BOOST;

LEDs:

- ^A SPEED button: airflow selector

Press repeatedly to select speeds:

• 0: Stand-by/fans off (LED 1+ LED 2 + LED 3 + LED 4: off);
• 1: Minimum flow rate (LED 1: on);
• 2: Average flow rate (LED 1 + LED 2: on);
• 3: High flow rate (LED 1 + LED 2 + LED 3: on);
• 4: Maximum flow rate (LED 1 + LED 2 + LED 3 + LED 4: on);

- Ⓑ= MODE button: fan mode selector

Press repeatedly to select modes:

• RECOVERY (LED RECOVERY: on);
• VENTILATION (LED VENTILATION: on);
• EXTRACTION (LED EXTRACTION: on).

- Ⓐ= BOOST button: max speed selector

Press repeatedly to select modes:

- BOOST on (BOOST LED + LED 1 + LED 2 + LED 3 + LED 4: on);

- BOOST off (BOOST LED + LED 1 + LED 2 + LED 3 + LED 4: off).

Heat recovery mode

Winter: Extracted air from the room (hot) is exploited to pre-heating the air supplied to the room (cold).

Summer: Extracted air from the room (cold) is exploited to pre-cooling the air supplied to the room (hot).

The connected devices cyclically reverse the direction of fan rotation (extracting and introducing air into the environment) with a set cycle time.

Speed adjustment (of devices) is automatic and ensures the correct balance of the Input/Output flow rates.

Further information on cycle time is provided in the paragraph "Setting operating parameters" under "Selecting cycle time".

Ventilation Mode

The devices change internal environment air (without recovering heat).

- Even number devices extract air from the environment.

- Odd number devices introduce air into the environment.

Speed adjustment (of devices) is automatic and ensures the correct balance of the Input/Output flow rates.

Further information on EVEN and ODD number devices is provided in the paragraph "Setting operating parameters" under "Selecting the number of devices to be checked".

Air Extraction Mode

All connected devices extract air from the internal environment.

The air flow rates are all in Output toward the external environment.

ENGLISH

Only for VENTILATION or RECOVERY modes:

In the event that 2,3,4,5,6 units are connected to the Remote Control, these units will be piloted so as to ensure the balance of the overall flow in ventilation mode with heat recovery.

In the case of “ODD Number” connected units (3/5), system balancing may require 2 units to be stopped, in rotation (depending on the speed setting). Further informations about “EVEN/ODD units number” are provided in the paragraph "Setting operating parameters", under “Selecting the number of devices to be controlled”).

Warning: filter replacement

Fig. 2

After the scheduled amount of filter replacement time (90,180,365 days), the steady LED FILTER light (red) will light up on the remote control display (without locking the device):

• LED FILTER off: filters clean;
• LED FILTER steady on: filters to be cleaned or replaced.

Further informations are provided in the paragraph "Setting operating parameters", under "Programming filter replacement".

Resetting the warning: filter replacement

The filter replacement warning (red steady on LED FILTER) must be reset after filter cleaning/replacement.

To reset the clogged filter counter:

o Simultaneously press the Speed - Mode - Boost buttons;
o Press the buttons Speed - Speed - Mode - Mode - Boost - Boost in sequence;
o Press any button without 30sec;
o The red LED FILTER will flash briefly to indicate reset has occurred and the machine will return to normal operation.

Important: if no button is pressed within 30sec, the BOOST LED (blue) will flash and the machine will return to normal operation without having first reset the filter timer.

Remote inputs to connect with environmental sensors and/or others Vortice air extractors

Fig. 7

Connecting with environmental sensors

It is possible to control devices VORT HRW 20 MONO D from a distance by means of environmental sensors (optional).

The environmental sensors foreseen for unit VORT HRW 20 MONO D are as follows:

• C TEMP = temperature sensor;
• C HCS = humidity sensor;
• C SMOKE = smoke sensor.

Environmental sensors can be connected to the Remote Control by means of clean On/Off contacts on the Remote inputs: #1, #2 and #3 present on the circuit board:

• Remote Input #1 - Air extraction at maximum speed;
• Remote Input #2 - Heat recovery at maximum speed;
• Remote Input #3 - Air supply at maximum speed.

These modes will be activated independently of the current speed settings.

Connecting with others Extractors

To compensate extracted airflows, others Vortice air extractors can be connected to devices VORT HRW 20 MONO D.

Others Vortice air extractors can be connected to the Remote Control by means of clean On/Off contacts on the Remote input # 3 present on the circuit board:

- Remote Input #3 - Air supply at maximum speed.

This mode will be activated independently of the current speed settings.
