3.1.12 System cooling
When the adjusted maximum store temperature is
reached, the system stagnates. If the collector tempe-
rature increases to the adjusted maximum collector
temperature (
CMX ), the solar pump is activated until
the collector temperature falls below the maximum
collector temperature. The store tempe rature may
increase (subordinate active maximum store tempe-
rature), but only up to 95 °C (emergency shutdown of
the store).

OFF ... ON
Factory setting: OFF
3.1.13 Minimum collector function
OCN:
Mimimum collector function
Adjustment range: OFF / ON
Factory setting: OFF
The minimum collector temperature is the minimum
temperature which must be exceeded for the solar
pump (R1) to switch on. The minimum temperature
prevents the pump from being switched on too often
at low collector temperatures. If the temperature falls
below the minimum temperature, (flashing) is shown
on the display.
3.1.11 Collector emergency shutdown temperature If the adjusted collector emergency shutdown
temperature (
EM
) is exceeded, the controller will switch
off the solar pump (R1) in order to protect the system
against overheating (collector emergency shutdown).
The factoring setting is 140 °C but it can be changed
within the adjustment range of 110 ... 200 °C. (flashing)
is displayed.
EM
:
Collector emergency
shutdown temperature
Adjustment range:
110 ... 200 °C
Factory setting: 140 °C
If OREC is additionally enabled: If the store tempe rature is higher than the maximum
store temperature (
S MX
) and if the collector tempe-
rature is at least 5 K below the store temperature, the
solar system remains activated until the store is cooled
down below the adjusted maximum temperature (
S
MX
) via the collector and the pipework.
If the system cooling function is enabled, (flashing) is
shown on the display. Due to the cooling function, the
system will have a longer operation time on hot sum-
mer days and guarantees thermal relief of the collector
field and the heat transfer fluid.
