If this function is activated, the pump speed control logic will change. The controller will remain
at the minimum pump speed until the temperature at the allocated sensor exceeds the adjusted
target temperature. Only then will the standard pump speed control start to operate. If the tem-
perature at the allocated sensor changes by 1/10 of the adjusted rise value, the pump speed will
be adjusted correspondingly.
If the Ext. HX function with the Targ. temp. option (see page 132) is additionally activated,
the target temperature control will pause while the external heat exchanger is loaded. While the
external heat exchanger is loaded, its own pump speed control will come into effect.

Funct. Activation / Deactivation
Sensor Switch input selection
This function activates the loading circuit between the collector and the store when the collector
temperature falls below the adjusted switch-on temperature. This will protect the fluid against
freezing or coagulating. If the switch-off temperature is exceeded, the solar pump will be
switched off again.
Heat will be extracted from the stores according to the adjusted order. When all stores have
reached their minimum temperature of 5 °C, the function becomes inactive.
If the function is activated, the pump will run at its maximum relative speed.
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.
This function should only be used in systems which do not use any antifreeze.
NOTE:
In systems with 2 or 3 collector fields, 2 or 3 separate menus will be displayed.
