The logic of solar thermal power function is as follows:
The pump will start when the below conditions are satisfied at the same time:
•
The unit is on;
•
T6 (temperature of solar collector - thermosensor 18)
≥
T2 (lower tank water temper-
ature) + parameter 17;
•
T2 (lower tank water temperature)
≤
78°C
The pump will stop when one of the below conditions is satisfied:
•
The unit is off;
•
T6 (temperature of solar collector - thermosensor 18)
≥
T2 (lower tank water temper-
ature) + parameter 18
•
T2 (lower tank water temperature)
≥
83°C
While solar thermal function is active, the compressor of heat pump is running too.
