3.2.8 Limit collector temperature (
CLCL
CLCL
CL)
Extremely high collector temperatures are normally
intercepted by a properly dimensioned membrane-
expansionball. If the preadjusted collector limit temperature
(CL) is exceeded, the solar pump (R1) is switched-off 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.
3.2.9 Maximum collector temperature (
CXCX
CXCX
CX)
If the collector temperature exceeds the adjusted maximum
collector temperature (CX) in standstill of the solar circuit
(maximum store temperature is reached), the solar pump
(R1) 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 90 °C (safety
shutdown of the store). This function guarantees a longer
operating time for very hot summer days and ensures a ther-
mal 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.
3.2.11Recooling function
Recooling (
FN 2FN 2
FN 2FN 2
FN 2):
If the adjusted maximum store temperature (
S XS X
S XS X
S X) is
exceeded, the solar pump remains activated in order to avoid
an overheating of the collector. The store temperature may
incease - but only up to 90 °C (store safety shutdown).
The solar systems remains running in the evening until the
store is cooled down to the adjusted maximum store
temperature (
S XS X
S XS X
S X) by the collector or lines.
The minimum collector temperature is a minimum switching
temperature, which must be exceeded so that the solar
pump (R1) 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.
