This function is a further possibility to activate the solar circuit.
Note
To enable the use of the CS bypass function, a CS10 irradiation sensor has
to be connected.
When the CS bypass function is activated, the irradiation value is the switch-on
condition for the collector circuit.
The output switches on if the irradiation value is exceeded for the delay time. If
the irradiation falls below the adjusted irradiation value for the adjusted delay, the
output switches off.
If the switch-on suppression option off is activated, collector circuit activation will
be suppressed as long as all store temperatures are above their respective maxi-
mum temperatures.
Note
If both the CS bypass and the bypass function are activated, the CS bypass
will only affect the bypass. For this purpose, use S1 as the bypass sensor.

This function is used to link loading circuits that are separated by an external heat
exchanger.
The allocated output is energised if one of the selected stores is being loaded and
there is a temperature difference between the sensor of the corresponding store
and the reference sensor external heat exchanger.
Any number of the solar stores can be selected.
The output is switched off if this temperature difference falls below the adjusted
switch-off difference.
Note
In systems in which stores are equipped with their own loading pumps, the
heat exchanger relay controls the primary circuit pump.
