In case of difficulty
PROBLEM SOLUTIONS
Thermostat is hot. This is normal.
Displayed tempera-
ture is wrong.
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.
Display disappears
and reappears after a
few minutes.
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.
