block if ThSt temp. lower than zone min. temperat. (yes/no) Blocks the zone when ThSt
temperature (ThSt upper sensor) is lower than min. heating water
temperature. Prevents extensive cooling of the thermal store.
S 2.2 – Solar Zone Service Parameters Setting
Solar system may work with one, two or three hot water storage tanks. Their heating is
controlled by so call oscillating heating, i.e. the Controller tries to heat up Tank No. 1 first. If
this is not possible due to a low temperature difference between a solar collector and the
tank, and at the same time the difference for heating Tank 2 is sufficient, the Controller starts
heating Tank 2 for the preset time. After that time, the Controller interrupts heating Tank 2
and tests if a collector temperature grows. If not, heating Tank 2 continues. If the collector
temperature grows, the Controller waits until the temperature difference is fulfilled for Tank 1
and then its heating is started. Heating to Tank 3 is controlled in a similar way.
Solar (active/off) Switching on solar zone.
tank 1,2,3 (active/off) Switching on separate solar tanks.
The following two displays are the same for all the three tanks:
sensor (sensor list) Choice of temperature sensor in a solar tank.
For control type 2 the heating return sensor is replaced by the flow sensor in zone 1!!!
