condition of switching difference is met – cf. more details in the
description of Oscillating loading function.
idle time (min)
Time period the Controller idles, waiting if the solar collector
temperature rises. The description see parameter t. increase.
sol.tank 2(3) (min)
If a tank of higher priority cannot be loaded, a tank of lower priority is
loaded for the time period set in this parameter.
Collector cooling function:
When this function is on, solar collector is cooled. As soon as the max. temperature is
reached (in all tanks), tanks loading is stopped. When the solar collector temperature
exceeds the preset max. collector temperature, the circulation pump starts and the collector
is cooled by heating tank X. If the temperature in tank X exceeds the preset critical
temperature, collector cooling is stopped. Tank number (X) is set in parameter
nmbr. of
solar tank for collect. cooling and tank cooling
(see Solar tank cooling function).
on (active/off)
Switching on the function of collector cooling.
crit.storT (°C)
Setting the critical tank temperature. Collector cooling by heating tank 1 may
run only until the tank temperature set by this parameter is reached. When this
temperature is exceeded in tank 1, the collector stops cooling.
max.coll.T (°C)
Max. collector temperature. When this value is exceeded, collector cooling by
heating tank 1 is started, supposed this function is on.
