Troubleshooting
Problem
Thermostat is hot.
Displayed temperature
is wrong.
Display disappears and
reappears after a few
minutes.
Solution(s)
Under normal operation, the thermostat housing can reach a
temperature between 35 °C (95 °F) and 40 °C (104 °F).
Remediate if any the following conditions exists:
• The thermostat is exposed to air draft.
• The sticker on the thermostat's screen has not been removed.
• The thermostat is located near or above a heat source such as a
light dimmer.
The thermal protection device on the heater has temporarily opened.
This can happen if the heater is obstructed by furniture or curtain
and has overheated, or if the heater's thermal protection device is too
sensitive.
