Thermostat is hot.
This is normal unless the thermostat is too hot 
to touch. Ensure that the heater capacity does 
not exceed the thermostat’s maximum load.
Wrong temperature is 
displayed.
Avoid any of the following conditions:
• The thermostat is exposed to an air draft.
• The thermostat is located near or above a
heat source such as a light dimmer.
Display disappears and 
reappears after a few 
minutes.
The thermal circuit breaker on the heater has 
temporarily opened. This can happen if the 
heater is obstructed by furniture or curtain and 
has overheated, or if the thermal circuit 
breaker is defective or too sensitive.
Display looks faded 
when heating is acti-
vated.
The heater capacity is probably less than the 
thermostat minimum load requirement. The 
thermostat cannot be used below that rating.
