Problem
Description
Solution
1
The thermostat is hot.
In normal operating conditions, the thermostat housing can reach
nearly 104°F (40°C) at maximum load. That is normal and will not
affect the effective operation of the thermostat.
2
Heating is always on.
Check to be sure that the thermostat is properly connected. Refer
to the installation section.
3
Heating does not run
even if the thermostat
indicates it is on.
Check if the thermostat is properly connected. Refer to the
installation section.
4
The display does not
come on.
Check if the thermostat is properly connected. Refer to the
installation section. Check the power supply at the electrical
panel. Check if the heating unit has a switch. If so, check the
circuit breaker and intervening switches performance.
5
The display turns off a
few minutes and then
turns on again.
The thermal protection of the heating unit has deactivated the unit
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.
6
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.
7
The displayed ambient
temperature is
incorrect.
Check the presence of an air stream or a heat source near the
thermostat, and correct the situation. Note that the thermostat
measures dry bulb air temperature at the location of the
thermostat.
8
The display indicates
E1 or E2.
Faulty thermal sensor. Contact customer service.
9
Weak luminosity of the
display.
Possibility of a bad contact. Check thermostat wirings. Refer to
the installation section.
