TROUBLESHOOTING

Safety thermostat in electric heater

If a fault occurs in the built-in electric heater, the safety 

thermostat will switch off the unit. The electric heater is 

equipped with a fire thermostat, which automatically  

shuts off the power if the temperature exceeds 40°C.  

When the temperature falls, the heater switches on again 

automatically.

As an extra safety feature, there is a built-in thermal fuse 

which triggers disconnection if the temperature exceeds 

60°C.

Reconnection must be executed manually via the red button 

indicated in the pictures below.

The red reset button can be activated through the fan 

housing with a screwdriver. REMEMBER to disconnect the 

power from the system!

System not running

•  Fuse in electric panel has blown, no voltage in the 

system.

•  One of the fuses in the system’s control board has blown.

•  Loose cable, no voltage to the unit.

•  Incorrectly set weekly program.

•  Filter timer has switched off the system.

 

No supply air 

•  Defective supply air fan.

•  Clogged supply air filter.

•  Outdoor air grille clogged with dirt and leaves during 

autumn or snow and ice during winter.

•  Fuse on control board has blown.

•  Unit is defrosting (supply air fan runs at reduced speed)

•  Incorrect setting of Optima controls

No exhaust air

•  Defective exhaust fan.

•  Clogged exhaust filter.

Fault

•  Heat exchanger is clogged.

•  The exhaust fan is defective.

•  The exhaust air filter is clogged.

•  The electric preheating surface is disconnected from the

•  Air in heating pipe, defective thermostat/motor valve, 

incorrect setting of control panel.

If none of the above errors are relevant, contact:

•  During the warranty period (0-2 years), the installer from 

whom the unit was purchased.

•  After the warranty period (2 years ->), the installer from 

whom the unit was purchased or the Genvex Customer
