BYPR: Transfer of thermal excess energy from the storage tank
Description
This function is independent of the solar collector array. It is used to transfer excess thermal energy from
the storage tank to other units, thereby keeping the tank temperature constant. This requires an extra
pump or solenoid valve, which is connected to output R3.
For example
If the activation temperature for the transfer of excess thermal energy is set to 70°C, and the storage tank
temperature (T2) rises to 71°C, the pump/solenoid valve (R1) and the solar collector circulation pump
(P1) are activated simultaneously. When the storage tank temperature (T2) drops to 67°C, the
pump/solenoid valve (R1) and the solar collector circulation pump (P1) are switched off.
Setting
