4.15. MoUnTInG THE SEnSorS
4.15.1. Water Temperature Sensor
The water temperature sensor can be inserted into a suitable immersion well or strapped on to a pipe using the supplied
metal clip.

note
For strap-on mounting, the metal clip must be used and tightened firmly to provide a good thermal connection. A -
badly-mounted sensor can cause control problems.
The best location for measuring the temperature and, therefore, inserting the sensor, is the immersion well for boiler
temperature displays, boiler thermostat, and safe temperature guard. There is usually space for the sensor in this well
(sensor cartridge: 6.5 mm Ø, 50 mm long).
In order to have good heat transmission between the sensor cartridge and the immersion well, the contact strip supplied
must be inserted along with the cartridge. If there is no space in the well for the sensor, another separate well can be used
near the aforementioned immersion well.
