Collector minimum limitation
Adjustment range: OFF / ON
Factory setting: OFF
If the collector minimum limitation option is activated,
the pump (R1) is only switched on if the adjustable
collector minimum temperature is exceeded. The minimum
temperature prevents the pump from being switched on too
often at low collector temperatures. A fixed hysteresis of
5 °K [10 °Ra] is set for this function
If the collector minimum limitation is active, (flashing) is
shown on the display.
Antifreeze option
/#&
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 below
the adjusted antifreeze temperature. This will protect the
fluid against freezing or coagulating. If the adjusted antifreeze
temperature is exceeded by 1 K [2 °Ra], the loading circuit
will be deactivated.
When the antifreeze function is activated,
is shown on
the display. If the antifreeze function is active,
and
(flashing) are shown on the display.

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.
The antifreeze function will be suppressed if the
store temperature falls below 5 °C [40 °F] in
order to protect the store from frost damage.

Store cooling function
When the store cooling function is activated, the controller
aims to cool down the store during the night in order to
prepare it for solar loading on the following day.
If the adjusted maximum store temperature
S MX
is
exceeded and the collector temperature falls below the
store temperature, the system will be reactivated in order
to cool down the store. Cooling will continue until the store
temperature has fallen below the adjusted maximum store
temperature
S MX
again. A fixed hysteresis of 2 K [4 °Ra]
is set for this function.
Reference threshold temperature differences for the store
cooling function are

If no DHW consumption is expected for a longer period of
time, the additional holiday cooling option
/(/,
can be
activated in order to extend the store cooling function. The
adjustable temperature
4(/,
then replaces the maximum
store temperature
S MX
as a switch-off temperature for the
store cooling function.
