Store heat dump option
This option can be used to direct excess heat generated by strong solar irradiation from the
store to an external heat exchanger (e.g. fan coil) or radiator in order to prevent the collectors
from overheating. The store heat dump function is independent of the solar system and can
be activated with the parameter Heat dump. The function uses the adjustable switch-on and
switch-off temperature differences TStoreOn and TStoreOff.
If the temperature measured at the sensor selected reaches the switch-on temperature, the out-
put selected will be energised until the temperature difference falls below the switch-off value.
