5 - OPERATION
After this configuration, the unit is able to:
- Carry out the Heating / Cooling switchover using the manual
selector “42” (switch to be made at each season change).
The call relating to “Zone 2” will be made by the room
thermostat “43”.
- Be called in heating / cooling on “Circuit 1” by closing the
room thermostat “43” and input “14”.
- Switch between heat pump and boiler when the outside
temperature drops below a certain value.
The closure of input “14” alone is unable to start Zone 1.
Since it is necessary to close both the room thermostat
“43” and the input “14”, the call of Zone 1 inevitably also
starts Zone 2.
- Domestic hot water production in priority over heating / cooling;
- Call the boiler as a supplement to heating and domestic hot
water production whenever the heat pump fails to reach the
domestic hot water set point and / or the heating set point
within a certain period of time.
