TECHNICAL INFORMATION

2.1. GENERAL INFORMATION
The DOMEO ensures optimum ventilation of a house with a maximum energy recovery. It draws air from the rooms (bathroom(s), toilet, kitchen and wash room(s)) and supplies fresh air through the main rooms (living room, bedroom (s), offi ce, etc ).
The fresh and extract airfl ows are separated and fi ltered. Only heat energy is transferred to the fresh fi ltered air that is introduced.
Due to the high-effi ciency heat exchanger used in the DOMEO performance can reach 95%.
Condensation forms during the heat exchange process and is recovered in the condensate tray, which must be connected to a waste water drain.
The DOMEO is equipped with a double condensate drain system that allows a propper working in winter (heating) and summer (cooling).
The DOMEO has a 100% heat exchanger bypass system and this allows the introduction of fresh air at night without it being heated by contact with warm air accumulated in the house during the day. The system operates automatically or  can be used manually (see section 5-2).

2.2. DESCRIPTION

| Outdoor air (ODA):
It is recommended to install the fresh air intake (wall or roof) at a suffi cient distance from any area with high pollution (trees, exhaust fumes, road. etc.)
This duct must be sealed and insulated to prevent condensation.
---|---
| Supply air (SUP):
To avoid thermal losses and optimize the performance of the installation, it is recommended to use insulated ducts.
| Extract air (ETA):
To avoid thermal losses and optimize the performance of the installation, it is recommended to use insulated ducts.
| Exhaust air (EHA):
This duct must be sealed and insulated to prevent condensation.
| By-pass:
The DOMEO has a 100% heat exchanger bypass system which allows free cooling by night. The principle of freecooling uses free energy from the outdoor air to ventilate and cool buildings when outdoor air temperature is lower than the exhaust air temperature.

INSTALLATION

The DOMEO heat recovery unit is designed for indoor installation. We recommend a min. temperature of +10ºC in the room where the unit is installed to guarantee a good effi ciency of the unit.
In areas where temperatures can be below -10ºC in the winter time, it is necessary to install a pre-heating device.
****In all Passive House applications the pre-heater is mandatory.

Summer condensation
In very humid zones in the summer time there could be condensation on the supply side when indoor air is cooled therefore we supply an additional drain connector in order to install if needed (see pictures below).

4.2. SPCM-WB COMMUNICATIONS MODULE CONNECTION FOR IOT CONNECTAIR CONNECTION (OPTIONAL)
Note: The SPCM communication module is not compatible with the use of the remote controller included with the DOMEO unit.
To connect the SPCM-WB communications module to the unit, please follow the following instructions:

• First, disconnect the unit from the power.
• Disconnect the remote control from the main board.
• Fix the SPCM-WB in the hole located in the upper left hand corner, above the main board. This is done by inserting a screw into the EPP body of the DOMEO unit through a clip on the module (see drawing 1).
• Once fi xed, connect the SPCM-WB with the cable supplied to the central board in the Modbus terminal block. (see drawing 2).
• Finally, change position of Jumper J1 from open to closed (see drawing 3).
• The installed set will be as per image 4.

This allows the unit to be controlled through the CONNECTAIR platform rather than the remote control, which improves the functionality of the unit.

COMMISSIONING OF THE DOMEO

5.1. FOR INSTALLATION:
The remote control allows:

• Adjust the airfl ows (1st speed, 2nd speed, 3rd speed)
• Timer for adjusting the fi lter maintenance period (6, 9, 12 or 15 months) (factory setting 12 months)
• Adjust the balance of supply / extraction airfl ows

5.1.a Airfl ow adjustment

To adjust the airfl ow turn the potentiometer carefully clock wise with a small screw driver.
Factory setting: 1st speed = position 3; 2nd speed = position 5; 3rd speed = position 7 (The curves below are showing the airfl ow according to the position of the potentiometer)

5.1.b Adjustment of the fi lter maintenance period
It is possible to set maintenance period to 6, 9, 12 or 15 months (12 months factory setting). The fi lter clogging depends on the pollution of the area where the unit is installed. We recommend checking the time in which the filter clogs and adjusting this period.
It is  advisable to do this after the second fi lter change as the first filter life maybe reduced due to construction dust and humidity in the system. 

5.1.c Supply/extraction airfl ow adjustment
In the case that in the building is a chimney, gas oven or any apparatus which needs combustion air and there is no additional supply air opening for this, it is necessary to adjust the unit in the way that the combustion is not affected. It is  necessary to add a supplementary air supply equal to the extract airfl ow due to the natural draught of the chimney.
After fi nishing the installation it is recommended to use this feature to balance the airfl ows!

Example:

• Minimum calculated airfl ow = 90 m 3/h
• Supply airfl ow necessary = 99 m 3/h
  Potentiometer position 5 = +10%
  ****The adjustment is made on the supply airfl ow compared with extraction airfl ow.
