(Electrician Required)
Electrician required to verify that the
floor sensor has been wired correctly. If it is correctly wired
the electrician will need to check the resistance of the floor
sensor using a multi-meter. For temperatures between 20°C
- 30°C the resistance of the floor sensor should measure
between 8K ohms and 12K ohms.
If the electrician finds a fault, and the thermostat is in the
room to be heated then it can be set into “Air Mode”.
To set into “Air Mode” or “Regulator Mode”, see installer
setting #3.
