Solution  
In normal operating conditions, the thermostat housing can reach  
nearly 40°C / 100°F at maximum load. That is normal and will not  
affect the effective operation of the thermostat.  
The thermostat is hot.  
Check if the thermostat is properly connected. Refer to the installation  
section.  
Heating is always on.  
Heating does not run even if the  
thermostat indicates it is on.  
Check if the thermostat is properly connected. Refer to the installation  
section.  
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, ensure that this switch is turned on.  
The display does not turn on.  
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 unit is according to the manufacturer’s  
specifications.  
The display turns off a few  
minutes and then turns on again.  
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.  
The display indicates E1, E2,  
E3 or E4.  
Faulty thermostat. Contact the customer service.  
Possibility of a bad contact. Check thermostat wiring. Refer to the  
installation section.
