Cooling
This option is used to protect the collector liquid and works in the following
way. It activates the solar pump P1 or P2 if temperature on the collector
arrays T1 or T2 exceeds the "Max temp" value even if the set maximum
temperature in the tank is exceeded. The circulation stops when temperature
has dropped 10°C.
(The pumps will be stopped if the water temperature in the tank reaches
95°C).
5.5.3/ Recooling:
When the water temperature inside the tank is above the setting level (4.1)
and the collector temperature is 10°C under the pump is activated to cool the
tank through the collector array (during the night or...).
The pump will be turned off when the water temperature inside the tank has
dropped to the setting level (4.1) or when the difference between the tank and
collector array temperature is below 2°C
5.5.4/ Freeze prot:
This option will keep the solar panel temperature T1 or T2 above the Freeze
setting level (see below) by activating the pump P1 or P2.
This option could be used to reduce snow accumulation on the panel and
increases the efficiency during the day or to avoid the solar liquid damages.
Careful: it is preferable not to use this function in the too cold regions in order
not to use too much the energy stored in the tank
