Factory setting120 °C
4.1.11 System cooling
If the adjusted maximum store temperature is reached, the
solar system switches-off. If now the collector temperature
raises to the adjusted maximum collector temperature
(CMX), the solar pump remains activated until this limit
temperature value is again underrun. The store tempe-
rature might continue to raise (subordinated active
maximum store temperature), but only until 95 °C
(emergency shutdown of the store). If the store tempe-
rature is higher than the maximum store temperature
(SMX) and the collector temperature is lower by at least
5 K than the store temperature, the solar system remains
activated until the store is again cooled down by the
collector and the tubes under the adjusted maximum
temperature (S MX).
In case of active system cooling on the display is shown
(flashing). Due to the cooling function the solar system
can be kept operable for a longer period on hot summer
days and a thermal release of the collector and the heat
transfer medium is ensured as well.

4.1.12 Option minimum collector limitation
OCN:
Mimimum collector limitation
Adjustment range OFF / ON
Factory setting OFF
The minimum collector temperature is a minimum switching
temperature, which must be exceeded so that the solar
pump (R1/R2) is switched-on. The minimum temperature
shall avoid a steady starting-up of the solar pump (or solid
fuel boiler charging pumps) for low collector temperatures.
If the minimum temperature is underrun, in the display is
shown (flashing).
CFR :
Antifreeze temperature
Adjustment range
-10 ... 10 °C
Factory setting 4,0 °C
4.1.13 Option antifreeze function
OCF:
Antifreeze function
Adjustment range
OFF / ON
Factory setting OFF
The antifreeze function activates the loading circuit between
collector and store if the adjusted antifreeze function is
underrun in order to protect the medium that it will not
freeze or „get thick“. If the adjusted antifreeze temperature
is exceeded by 1 °C, the loading circuit will be
deactivated.
Please note:
As there is only a limited heat quantity of the store available
for this function, the antifreeze function should only be
used in regions with few days of temperatures around
freezing point.
4.1.10 Limit collector temperature
Collector emergency shutdown
If the adjusted collector limit temperature (EM) is exceeded,
the solar pump (R1/R2) is deactivated in order to avoid a
damaging overheating of the solar components (collector
emergency shutdown). The limit temperature is set to 140 °C
by RESOL but it can be changed within the adjustment
range of 110 ... 200 °C. In the display is shown (flashing).
