5.3 Installing the DHW water temperature sensor
(accessory) or Aquastat (accessory)
Install a tank temperature sensor or an aquastat on the DHW tank to
measure and monitor the hot water temperature.
Installing the DHW temperature sensor
Take the tank temperature sensor from the scope of delivery of the
control panel (accessories).
Insert the sensor set until it bottoms out inside the sensor well [5].
This automatically pushes back the plastic spiral [3] that holds the
sensor set together.
The compensating spring [4] ensures contact between the sensor well
and sensor surfaces, ensuring reliable sensing of the temperature.

[5] Sensor Well
Push sensor retaining clip [1] from the side onto sensor well [2].
Route the sensor lead to the boiler or control panel and ensure the
cable is not strained. This cable must not be in contact with any hot
boiler parts.
In the case a sensor is being used without a compensating spring, the
empty space in the sensor well must be filled with a sufficient amount
of heat-conducting paste.

top.
If necessary, remove any unnecessary attachments. Attach bracket
[3] to aquastat [2] by means of two self-tapping screws [1].

DANGER: Risk of fatal injury from electric shock.
Isolate the system electrically prior to commencing
work on the system.
Connect the electrical power and set the temperature on
the DHW temperature sensor or the aquastat as shown in
the respective aquastat or control manufacturer's
instructions.
Always ensure that the full length of the sensor surface is
in contact with the sensor well.
