Cylinder temperature sensor or temperature sensor for swim-
ming pool/heating water buffer cylinder
For connection inside the appliance
On-site extension of the connecting lead:
■ 2-core lead, length up to 60 m with a cross-section of 1.5 mm
2
(copper)
■ Never route this lead immediately next to 230/400 V cables
Lead length
3.75 m
IP rating
IP 32 to EN 60529; ensure through de-
sign/installation
Sensor type
Viessmann NTC 10 kΩ at 25 °C
Permissible ambient temperature
– Operation
0 to +90 °C
– Storage and transport
−20 to +70 °C
In systems with Viessmann DHW cylinders, the cylinder temperature
sensor is fitted directly into the threaded elbow in the heating water
return: see "Specification" chapter of the relevant DHW cylinder and
"Installation accessories" chapter.
If the swimming pool temperature sensor is used to record the water
temperature of the pool, the stainless steel sensor well available as
an accessory can be installed directly in the swimming pool return
line.
Functions
■ Switching the solar circuit pumps for DHW and/or swimming pool
water heating and other loads
■ Electronic limiter for the temperature in the DHW cylinder (safety
shutdown at 90 °C)
■ Collector safety shutdown
■ DHW
and
swimming pool water heating:
DHW heating can be set as a priority. While heating the pool water
(the lower set temperature load), the circulation pump is switched
off for the duration. It can thus be determined whether the DHW
cylinder (the higher set temperature load) can be recharged. If the
DHW cylinder is fully heated or the temperature of the heat trans-
fer medium is insufficient for heating the DHW cylinder, the swim-
ming pool water will continue to be heated.
■ Using the heating water buffer cylinder to heat DHW
and
heating
water:
The buffer cylinder water is heated by solar energy. The DHW
water is heated by the buffer cylinder water. If the temperature in
the heating water buffer cylinder exceeds the heating return tem-
perature by the specified value, a 3-way valve is switched. The
heating return water is fed via the heating water buffer cylinder to
the boiler in order to raise the return temperature.
