ModBus RS485 (FBus2) Communication Port
Internal terminals with thT bus communication data can be connected to this terminal.
5.2. Heat pump power supply
Depending on the model, the heat pump may require single phase 1/N/PE 230 V / 50 Hz power or three phase 3/N/PE 400 V / 50 Hz
power.
The heat pumps should be powered by an external automatic breaker that shuts down all the circuits. Shown below are the
recommended cable diameters for each heat pump model and the recommended range of external electric thermal-magnetic
protection. Maximum heat pump electrical consumption can vary widely depending on working conditions; for more information,
please refer to the Technical Service Manual.

To carry out the electrical installation, insert the power cable through the rear cover of the heat pump and pass it to the bottom right
part of the heat pump. Continue by connecting the cables to the power terminal block of the heat pump, as described below.

5.3. Internal auxiliary equipment power supply
The ecoGEO heat pumps are equipped with an internal auxiliary heater comprised by three 2 kW components each (6 kW in all) that
requires an independent power supply. This heater can be connected to either a single phase or three phase power supply, depending
on the thermal power required.
If the power supply is single phase 1/N/PE 230 V / 50 Hz, each of the elements can be connected independently to obtain 2 kW, 4 kW
or 6 kW, respectively.
