3.2.6 Limit collector temperature (
CL 1/CL 2
)
If the adjusted collector temperature limit (CL1/2) is
exceeded the solar pump (R1/R2) is deactivated in order
to avoid a damaging overheating of the solar components
(collector safety 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
and
if the maximum collector temperature is
exceeded, the operating control lamp flashes red.

3.2.7 Maximum collector temperature (
CX 1/CX
2
)
If the collector temperature exceeds the adjusted maximum
collector temperature (CX1/2) in standstill of the solar
circuit (maximum store temperature is reached), the solar
pump (R1/R2) switches-on and cools the collectors by heat
transfer via lines and the store (collector cooling function).
The store temperature might increase, but only up to 95 °C
(safety shutdown of the store). This function guarantees a
longer operating time for very hot summer days and ensures
a thermal relief for the collectors and the heating medium.
The maximum collector temperature is set to 120 °C by
RESOL, but it can be changed within the adjustment range
of 100 °C ... 190 °C. In the display is shown
,
and
if the maximum collector temperature is exceeded, the
operating control lamp flashes green.

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.The minimum temperature is set to 10 °C by
RESOL (= deactivated). In the display is shown
and
if the minimum collector temperature is exceeded, the
operating control lamp flashes green. This function analogly
is also usable as minimum temperature limitation for solid
fuel boilers, recommended adjustment value: 60 °C.
Please note:
The minimum collector temperature is used for adjustment
of the frost protection function between -10,0 ... 9,9 °C for
minimum temperature function between 10,1 ... 90 °C.
