conditions, the thermostat
housing can reach nearly
40°C at maximum load. That
is normal and will not affect
the effective operation of the
thermostat.
Heating is always on.
Check if the thermostat is
properly connected. Refer to
the installation section.
Heating does not run
even if the thermostat
indicates it is on.
Check if the thermostat is
properly connected. Refer to
the installation section.

come on.
Check if the thermostat is
properly connected. Refer

Check the power supply at the
electrical panel. Check if the
heating unit has a switch. If
so, ensure that this switch is
turned on.
The display turns off a
few minutes and then
turns on again.
The thermal protection of
the heating unit has opened
due to overheating. Check
if the heating unit is in good
condition of operation and
that clearance around the
appliance is according to the
manufacturer’s specifications.
The display has low
contrast when heating
is on.
The load is lower than the
minimum load. Install a
heating unit that is within the
load limits of the thermostat.
The displayed ambient
temperature is
incorrect.
Check the presence of an air
stream or a heat source near
the thermostat, and correct
the situation.
