The TCC function provides the possibility of raising the water temperature when an alternative power source
is available (solar photovoltaic, wind or other), increasing the efficiency of the heat pump and making
the alternative power source profitable.
To this end, it is sufficient to connect a cable from the inverter to the equipment's control board. The cable
connection on the control board must be made at the voltage-controlled terminals. It should be noted that
this is a dry contact (no voltage), applying a voltage to this contact can cause irreversible damage to the
controller.
When the voltage-controlled contact closes it triggers the
TCC Function and all active heat sources (Heat Pump +
Electrical heater) are adjusted to new operating parameters.
The compressor assumes the P01TCC/ H01TCC parameters
and the electrical heater the P02TCC/ H02TCC parameters.
Note: When the voltage-controlled contact opens the
equipment assumes the previously adopted operating mode.
The PV contact can also be used to take advantage of the bi-
hourly tariff. For this a timer should be connected to the PV
contact, instead of the inverter.
