Frequently Asked Questions - ERS S40-400 Nibe

How often should I replace the filters in the ERS S40-400?

Filter replacement interval can be set in menu 1.2.6, between 1 and 24 months. The actual frequency depends on air particle levels. We recommend checking filters every 6 months and replacing as needed.

Can I convert the ERS S40-400 from left-handed to right-handed duct configuration?

Yes, the unit can be converted. Follow the instructions in the manual: remove insulation, humidity sensor, extract air sensor, re-heater, and regrate filters. You must also change the setting in menu 7.2.11 to 'Right'.

What should I do if ventilation seems low?

First check if the filters are clogged (replace if needed). Ensure the ventilation adjustment has been carried out. Verify that no external switches are activating reduced speed. If the fan speed is set to a lower mode, go to menu 1.2.1 and select 'Normal'.

How do I activate night cooling?

In menu 1.2.2, set 'Night cooling' to 'on'. Define the 'Start temp exhaust air' (20-30 °C) and 'Min. di. ind. temp. - outd. temp.' (3-10 °C). When conditions are met, the fans will run at speed 4 and heat recovery stops.

What is the purpose of the re-heater (EB18)?

The re-heater raises the supply air temperature when needed. It is activated in menu 7.2.11 ('Allow re-heater'). You can set an offset so the re-heater only starts when the supply air drops a certain number of degrees below the desired temperature.

How do I reset the filter cleaning reminder?

Go to menu 1.2.6 - 'Filter cleaning interval'. The menu shows remaining time until next reminder. You can reset active reminders from this menu after replacing the filters.

What safety precautions should I take before installing or servicing the unit?

Disconnect the power supply before any installation work. Only a qualified electrician should perform electrical connections. If the supply cable is damaged, it must be replaced by NIBE or an authorized person. Ensure the installation area temperature is between -38 °C and 50 °C.

Can I connect multiple ERS S40 units to one main product?

Yes, up to 4 ERS S40 units can be connected in series. Set the DIP switch (S3) on the AJB board accordingly (as shown in the manual). The boards are connected via communication cable.

What does the humidity sensor (BM20) do?

The humidity sensor in the exhaust air enables demand-controlled ventilation. It adjusts the rotor speed and fan speeds to maintain desired relative humidity based on measured exhaust humidity and calculated outdoor humidity.

Where can I find the serial number?

The serial number is located at the bottom right inside the front cover. Keep it for servicing and support.

According to Rule 2 (UNDERSCORE & LINE RULES), if the GT contains lines used for stylistic emphasis or as background (like ruled paper), the OCR result must ignore them. The provided OCR content is "____", which consists of four underscores. This is incorrect because underscores are not equivalent to a solid line and are not permitted under the “Stylistic/Background Lines (Ignore)” rule. Outputting underscores for a stylistic line is incorrect because it misinterprets the line as a fill-in-the-blank placeholder. Therefore, the OCR result is inconsistent with the Ground Truth.

rail. When placing on a horizontal surface, t the enclosed feet on the underside of ERS S40. It is important for the surface where ERS S40 is placed to be stable and to withstand the weight of the unit.

• Install with its back to an outside wall, ideally in a room where noise does not matter, in order to eliminate noise problems. If this is not possible, avoid placing it against a wall behind a bedroom or other room where noise may be a problem.
- Wherever the unit is located, walls to sound sensitive rooms should be tted with sound insulation.
- The HRV unit's installation area always has to have a temperature of at least -38 °C and max. 50 °C.

INSTALLATION AREA

Ventilation connections

General ventilation connections

The ventilation flow must comply with the applicable national standards.

- Ventilation installation must be carried out in accordance with current norms and directives.

The supply air ow must be lower than the exhaust air ow to prevent over pressure in the house.

- Provision must be made for inspection and cleaning of the duct.

Set the ventilation capacity in the main product's menu system (menu 7.1.4 - "Ventilation").

- The air duct system must be a minimum of air tightness class B.

Adjusting ventilation

- To prevent fan noise being transferred to the ventilation to obtain the necessary air exchange in every room of the devices, install silencers in suitable locations in the building, the exhaust air valve and the supply air inlet as well as the fans in the HRV unit must be correctly positioned and

- The extract air and outdoor air ducts are insulated using diusion-proof material along their entire lengths.

Immediately after installation adjust the ventilation so that it is set according to the projected value of the house.

- Ensure that the condensation insulation is fully sealed any joints and/or at lead-in nipples, silencers, roof cov or similar.

Incorrect adjustment of the ventilation may lead to reduced installation eciency and thus poorer operating economy, a poorer indoor climate and moisture damage in the building.

- The air must be routed to the outdoor air duct through an

outer wall grille in the facade. The outer wall grille must be installed so that it is protected from the weather and must be designed so that no rainwater and/or snow can penetrate the facade or follow the air into the duct.

Ventilation connections

FT-HANDED VERSION

- When positioning the outdoor air and extract air hood/grille, bear in mind that the two air ows must not short circuit to prevent the extract air from being drawn into ERS S40 again.

- A duct in a masonry chimney stack must not be used for extract air or outdoor air.

NOTE

To ensure a sealed connection to ERS S40, the supplied hose clips must be used for connecting the air ducts.

RIGHT-HAND VERSION

EXHAUST AIR DUCT /KITCHEN FAN

Exhaust air duct (kitchen fan) must not be connected to ERS S40.

To prevent cooking odours from being led to the ERS S40, the distance between the kitchen fan and the exhaust air valve must be taken into consideration. The distance must not be less than 1.5 m, but may vary between dierent installations.

Always use a kitchen fan when cooking.

Ventilation ow

Connect ERS S40 so that all the exhaust air, except kitchen duct air (kitchen fan), passes through the heat exchanger (EP29) in the product.

Electrical connection

NOTE

All electrical connections must be carried out an authorised electrician.

Electrical installation and wiring must be carried out in accordance with national provisions.

ERS S40 must not be powered during installation

Start-up and inspection

SETTING THE VENTILATION

The ventilation must be set according to applicable standards. Adjust the supply air ow to guarantee a negative pressure.

The settings are made in menu 7.1.4.

Even if ventilation is roughly set at installation it is important that a ventilation adjustment is ordered and permitted.

Caution

An incorrectly set ventilation flow can damage the house and may also increase energy consumption.

NOTE

Order a ventilation adjustment to complete the setting.

HUMIDITY

ERS S40 has a built-in humidity sensor (BM20) that is used when demand-controlled ventilation is required.

The speed of the rotor is regulated with respect to a set value depending on the humidity measured in the exhaust air, as well as the calculated humidity outdoors, to achieve the desired relative humidity in the home. The speed of the fans is also regulated, if necessary.

The settings for demand-controlled ventilation are made in menu 7.1.4.4.

Activating ERS S40

Cooling recovery: When there is no heating demand, ventilation recovery is stopped to prevent the house from being heated further. When it is warm indoors and even warmer outdoor, ERS S40 can be used to prevent the house from heating up more than necessary. During cooling recovery, the cooler air from the house is used to cool the incoming air.

"Cooling recovery" is started when the exhaust air temperature is a certain number of degrees below the outdoor temperature and it is warm outside.
