6.1 To do before the commissioning
• Make sure that the installation and electrical connection are correctly done.
• Visually examine the product and accessories for damage.
• Make sure that the safety devices are correctly installed.
• Make sure that there are no blockages in the air inlet and the air outlet.
• Make sure that installation material and unwanted objects are removed from the product and the ducts.
• Make sure the ventilation unit is working properly.
6.2 To configure the ventilation unit
Ventilation unit sends signal to start the geothermal heat exchanger on demand only when ventilation unit is configured
properly.
Configuration
1. Make sure the ventilation unit is ON.
2. Go to Service menu.
3. Enter password (default 1111)
4. Go to Components > Extra Controller > Extra Controller Mode menu and select GEO Exchanger option.
Change settings in the menus Configure preheater settings and Configure precooler settings.
Set-Point value is the desired air temperature in the air duct after the geothermal heat exchanger. Activation
temperature is the outdoor air temperature at which the heating and cooling should start.
5. Configure control signal. Go to Service > Output > DIGITAL menu. Select the digital output to which the ground
heat exchanger is connected. Example if it is connected to DO3 on the connection board, then select DIGITAL OUT-
PUT 3 and select Step Controller Y4 Extra Controller from the output type list.
6. Configure internal outdoor temperature sensor as extra controller temperature sensor. Go to Service > Input >
ANALOG > ANALOG INPUT 1 and change input configuration from Outdoor Air Temp. Sensor (OAT) to Extra
Controller Temp. Sensor (ECT).
7. After sensor configuration is changed, select analog input to which the newly installed duct temperature sensor
(OAT) is connected and configure input as Outdoor Air Temp. Sensor (OAT).
6.3 To vent the system
Fill and vent the system correctly. If the pump does not vent automatically:
• Press and hold the control button for 3 seconds then release.
The pump vent function is initiated and lasts 10 minutes. The top and bottom

When vent function is complete, the LED display shows the
previously set values of the pump.
6.4 To adjust the geothermal heat exchanger pump
Note:
• The ventilation unit turns ON the geothermal heat exchanger only when there is a demand for cooling or
heating. In order to adjust the pump, the geothermal heat exchanger has to be ON. If required, temporary
change settings on the ventilation unit to simulate demand for cooling or heating.
• Go to menu Service > Output > DIGITAL > Step Controller Y4 Extra Controller.
