recovery water pump.
The heat recovery is enabled through the Q8 switch installed on the unit and requires to adjust
settings on the unit controller in order to make it work as needed. First of all the function needs to
be enabled on the main controller in order to display all the settings related to this function. With

Modbus to the unit controller, which can display all relevant electrical data such as:
Line to Line Voltage (per phase and average)
Line Current (per phase and average)
Active Power
Cos Phi
Active Energy
More details are described in chapter 4.2.10. All these data can be also accessed from a BMS by
connecting it to a communication module. See the communication module manual for details on
the device and parameter settings.
Both the energy meter device and the unit controller need to be properly set. The instructions
below detail how to set the energy meter. Refer to the specific instructions of the energy meter for
