4.1.15 Tube collector function
If the controller detects an increase in collector temperature
by 2 K compared to the previously stored collector
temperature, the solar pump will be switched-on for
about 30 seconds in order to detect the fluid temperature.
The current collector temperature will be saved as a
new reference value. If the measured temperature (new
reference value) is exceeded by 2 K, the solar pump will
run for 30 seconds. If the switch-on difference between the
collector and the store is exceeded during the runtime of
the solar pump or the standstill of the system, the controller
will automatically switch to solar loading.
If the collector temperature deacreases by 2 K during
standstill, the switch-on value for the tube collector function
will be recalculated.

Factory setting: OFF
4.1.14 Recooling function
If the adjusted maximum store temperature (
S MX
) is
reached, the controller keeps the solar pump running in
order to prevent the collector from being overheated.
The store temperature may increase but only up to 95 °C
(emergency shutdown of the store).
The solar pump is switched on once the collector
temperature is lower than the store temperature. It is
switched off when the store is cooled down to the adjusted
maximum temperature via the collector and the pipework.

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
the collector and the store when the temperature falls be-
low the adjusted antifreeze temperature. This will protect
the fluid against freezing or coagulating. If the adjusted anti-
freeze temperature is exceeded by 1 °C, the loading circuit
will be deactivated.
Please note:
Since this function uses the limited heat quantity of the store,
the antifreeze function should be used in regions with few
days of temperatures around the freezing point.
