For systems with Viessmann DHW cylinders, the cylinder temperature
sensor is installed in the threaded elbow (see chapter "Specification"
of the relevant DHW cylinder and chapter "Installation accessories")
in the heating water return.
When a temperature sensor (swimming pool) is used to record the
swimming pool water temperature, the stainless steel sensor well
(accessories) can be installed directly into the swimming pool return.
Functions
■ Switching the solar circuit pumps for DHW and/or swimming pool
heating or other consumers
■ Electronic limiter for the temperature in the DHW cylinder (safety
shutdown at 90 °C)
■ Collector safety shutdown
■ DHW and swimming pool heating:
DHW heating can be set as a priority. When the swimming pool water
is heated (consumer with the lower set temperature), the circulation
pump will be switched OFF in accordance with a timer, to establish
whether the DHW cylinder (consumer with the higher set tempera-
ture) can be reheated. The system continues to heat the swimming
pool water, if the DHW cylinder is being heated or if the temperature
of the heat transfer medium is insufficient to heat it up.
■ DHW heating and central heating with a heating water buffer cylin-
der:
The buffer cylinder water is heated by solar energy. The DHW water
is heated by the buffer cylinder water. When the temperature inside
the heating water buffer cylinder exceeds the heating return tem-
perature by the set value, a 3-way valve is actuated and the heating
return water is routed via the heating water buffer cylinder to the
boiler to raise the return temperature.
For further functions, see chapter "Functions".
