Product Description
The Probe and Sensor are used to control temperature where moisture would be a problem i.e. in wet room or bathroom. It can also control floor temperature where overheating would cause damage.
The temperature of an underfloor heating system is controlled via a thermostat that reads the temperature of the room through sensors. With underfloor heating, it’s common for there to be two types of sensor installed, the usual air sensor (in the thermostat itself) as well as an underfloor heating probe, or floor sensor.

Installation
When installing a floor sensor, you should always follow the manufacturer’s instructions supplied however, there are some general rules that should be applied when installing any underfloor heating probe.
The probe should be placed equal distance between heating wires and should never cross a heating wire.
The probe can be installed either above or below your electric underfloor heating mat.
Areas in which the temperature may be affected such as near external doors or on heating pipes, should be avoided.
Test
During installation, the underfloor heating probe should be tested to ensure it is working correctly. This will be done by the installer. In order to do this, they will use a digital multimeter. A multimeter is an electronic measuring device that can usually measure voltage, resistance and current. In this case, your installer will be measuring resistance (ohms Ω).
To test if the underfloor heating sensor is working correctly, they will attach the multimeter probes to the floor sensor cable. At normal room temperature, the multimeter should read 10kΩ at 25°C. If this is the case your sensor cable is working correctly and the install can be completed.
