The tank water temperature sensed by lower probe T2 is mainly for heat
pump control (with eventual Electric Heater integration).
The tank water temperature sensed by upper probe T3 is for Electric
Heater only.
In case of default of one of the probes the related error will be displayed
and the other sensor will be used to control both Heat Pump and electrical
resistance.
6. Bollyterm operating
Bollyterm management is assigned to a controller that interfaces with the
user and allows:
• setting of operating parameters;
• management of alarm situations
• setting of user-modifiable parameters;
• verification of resources status.
