Connection of the DHW Tank Temperature Sensor
The sensor measures the domestic hot
water tank temperature. Heating systems with domestic hot
water heating (single-boiler systems
only)
1.
Install the DHW tank temperature
sensor.
See installation instructions
for domestic hot water tank
Please note:
When installing the sensor in DHW
tanks of other makes, make sure
that the sensor is pressed against
the sensor well of the DHW tank by
means of a suitable device.
2.
Ensure that the
maximum
permissible domestic hot water
temperature is not exceeded. If
necessary, install a suitable safety
device for this purpose.
Heating systems without domestic hot
water heating
Do
not
connect the DHW tank
temperature sensor.
Electrical connection
See page 42.
The sensor measures the boiler
water temperature of the boiler.
The boiler temperature sensor is
installed at the same time as the
boiler insulation.
Check the sensor
1.
Disconnect plug
%
in the
terminal compartment.
2.
Measure resistance of sensor at
terminals ”1” and ”2” of the plug
or ”2” and ”3” (if a second DHW
tank temperature sensor is
connected).

Compare the value measured with
the current temperature. If the
value differs significantly, check
installation and, if necessary,
replace sensor.
