SECTION III: SOLAR CONTROL SYSTEM
Should the switch-on difference between collector
and store be exceeded during the runtime of the
solar pump or the standstill of the system, the con-
troller automatically switches over to solar charging.
If the collector temperature falls by 2 K during the
standstill, the switch-on value for the special tube
collector function will be recalculated and the solar
pump won’t be switched-on.
Application area:
Vacuum tube collectors (possibly
flat plate collectors as well) in order to avoid switch-
on delays during a store load, as well as to avoid a
run of the solar pump during the night (the tempera-
tures measured during the day can be "stored" until
night by the vacuum in the collector tubes).
4.1.18 Thermostat function (ARR = 3)
The thermostat function works independently from
the solar operation and can e.g. be used or use of
surplus energy or an after-heating.
•
AH O < AH F
The thermostat function is used for after-heating.
•
AH O > AH F
The thermostat function is used for use of surplus
energy.
