The CS bypass function is a dierent possibility to
activate the collector circuit. 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 irra-
diation value is the switch-on condition for the col-
lector circuit.
The relay remains switched on if the irradiation val-
ue is exceeded for the delay time. When solar load-
ing begins or the irradiation value remains below
the switch-on value for the delay time, the relay is
switched o.
When the Stmax o option is activated, collector
circuit activation is suppressed as long as all store
temperatures are above their respective maximum
temperatures.
