The Vitosolic 200 captures the collector temperature via the collector
temperature sensor. If the set temperature differential between the
collector temperature sensor and the cylinder temperature sensor is
exceeded, the bypass pump is switched on.
The solar circuit pump is started and the bypass pump is stopped if the
temperature differential between the bypass sensor and the cylinder
temperature sensor is exceeded by 2.5 K.
Note
The pump of the Solar-Divicon is used as a bypass pump and the pump
for the solar pump assembly is used as a solar circuit pump.

Parallel relay with Vitosolic 200

With this function, a further relay will be switched (subject to the system
scheme) in addition to the relay that switches the circulation pump of
a solar consumer, e.g. to control a diverter valve.

Cylinder 2 (to 4) on with Vitosolic 200

In systems with several consumers.
With this function, consumers can be excluded from solar heating.

Cylinder heating with Vitosolic 200

This function heats a consumer within a certain range. This range is
determined by the sensor positions.

Cylinder priority control with Vitosolic 200

In systems with several consumers.

The solar control unit records the radiation intensity via the solar cell.
The bypass pump is started if the set insolation threshold is exceeded.
The bypass pump is switched off and the solar circuit pump is switched
on if the set temperature differential between the collector temperature
sensor and cylinder temperature sensor is exceeded.
The bypass pump will also be stopped if the insolation level falls below
the selected switching threshold (shutdown delay approx. 2.5 min).
Note
The pump of the Solar-Divicon is used as a bypass pump and the pump
for the solar pump assembly is used as a solar circuit pump.
Any break or short circuit of the cylinder temperature sensor is then
no longer reported.
It is possible to determine the order for heating the consumers.
A consumer can be selected to be heated only once all other consum-
ers have reached their set value. The selected consumer will not be
heated in cyclical operation.
