PROBLEM/ALERT POSSIBLE CAUSE AND SOLUTION
The fan heater is not operational
after installation.
• Check whether the fan heater’s wiring is correctly connected and that the caps are tightened rmly.
(See Connecting the wiring, page 6).
• For a fan heater with a power cord: Make sure the plug is connected to the socket and that the
socket is powered.
• Make sure that the circuit breaker corresponding to the heating system in the electrical panel is
closed (ON).
• If the problem persists, the thermostat may be defective. Contact Stelpro Customer Service.
The breaker goes off
when the fan heater starts.
• Check whether the fan heater’s wiring is correctly connected. See Connecting the wiring, page 6.
• Make sure the voltage supplied is adequate (see the nameplate).
• Make sure the circuit breaker or fuse is adequate for the requested power.
The temperature setpoint
is never reached.
• Make sure the voltage supplied is adequate (see the nameplate).
• Make sure the unit is powerful enough for the size of the room.
• The fan heater’s thermal protection has been triggered. Restart the fan heater (see Restarting the fan
heater after the thermal protection is triggered, p. 13).
• If a wall thermostat controls the fan heater, make sure it isn’t defective.
• If none of the solutions above work, one or more of the heating elements may be defective. Contact
Stelpro Customer Service.
The fan heater is operating
continuously.
• The built-in thermostat can control residual heating to maintain the temperature once the setpoint
temperature is reached. The fan heater may operate continuously for long periods of time without
stopping; this is normal behaviour.
• If the fan heater never stops, the thermostat or timer may be defective. Contact Stelpro Customer Service.
The ambient temperature
is too high.
• The fan heater may temporarily heat beyond the setpoint temperature but will never exceed it by
more than 1 °C (2 °F).
• Make sure that the heater is not oversized for the room.
• If the problem persists, the thermostat may be defective. Contact Stelpro Customer Service.
Heating is not operational.
• The fan heater’s thermal protection has been triggered. Restart the fan heater (see Restarting the fan
heater after the thermal protection is triggered, p. 13).
• Check if an open window has been detected. If so, close the window.
• Make sure the temperature setpoint is not too low.
• Check whether the fan heater’s wiring is correctly connected. See Connecting the wiring, page 6.
• If the problem persists, the thermostat or one of the heating elements may be defective. Contact
Stelpro Customer Service.
Heating stops, but the fan
continues to run.
• The fan heater is overheating, and the thermal protection has been triggered. Restart the fan heater
(see Restarting the fan heater after the thermal protection is triggered, p. 13).
• If the problem persists, it is possible an internal component is defective. Contact Stelpro Customer Service.
The temperature setpoint
cannot be changed on the built-
in thermostat (the buttons do
not respond, except to access
the advanced menus).
• Disable lock mode.
• BOOST mode is enabled. Wait for it to nish its cycle or deactivate it.
With a wall thermostat:
thefan heater turns on and off
frequently.
• Make sure the wall thermostat is in fan mode.
With a wall thermostat: the fan
heater makes a buzzing sound.
• The fan heater’s thermal protection has been triggered. Restart the fan heater (see the Restarting the
fan heater after the thermal protection is triggered p.13).
