PROBLEM/ALERT POSSIBLE CAUSE AND SOLUTION
The fan
heater is not
operational
after
installation.
• Make sure the temperature setpoint is not too low.
• Check whether the fan heater’s wiring is correctly
connected. See Connecting the wiring, page 7.
• Make sure that the circuit breaker correspond-
ing 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 o
when the fan
heater starts.
• Check whether the fan heater’s wiring is correctly
connected. See Connecting the wiring, page 7.
• 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 is overheating, and the thermal
protection has been triggered. Make sure the unit’s
air inlet and air outlet are not obstructed. Once
the cause of overheating is eliminated, the unit will
resume operating after a few minutes.
• 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.
• Check whether the timer is at zero.
• Make sure the unit is powerful enough for the size
of the room.
• If the fan heater never stops, the thermostat or
timer may be defective. Contact STELPRO Cus-
tomer Service.
PROBLEM/ALERT POSSIBLE CAUSE AND SOLUTION
The ambient
temperature
is too high.
• Make sure the temperature setpoint is adequate.
• If the problem persists, the thermostat may be
defective. Contact STELPRO Customer Service.
Heating is not
operational.
• The fan heater is overheating, and the thermal
protection has been triggered. Make sure the unit’s
air inlet and air outlet are not obstructed. Once
the cause of overheating is eliminated, the unit will
resume operating after a few minutes.
• Make sure the temperature setpoint is not too low.
• Check whether the fan heater’s wiring is cor-
rectly connected. See Connecting the wiring,
page 7.
• 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. Make sure the unit’s
air inlet and air outlet are not obstructed. Once
the cause of overheating is eliminated, the unit will
resume operating after a few minutes.
• Make sure the air inlet and air outlet are not
obstructed. Clean them, if necessary, then turn the
fan heater back on. Maintaining the fan heater,
page 15.
• If the problem persists, it is possible an internal
component is defective. Contact STELPRO Cus-
tomer Service.
With a wall
thermostat:
the fan heater
turns on and
o frequently.
• Make sure the wall thermostat is in fan mode.
RESTARTING THE FAN HEATER AFTER THE THERMAL PROTECTION IS TRIGGERED
In the event of overheating, the unit’s thermal protection will trigger to prevent damage. When this happens, heating is switched o,
but ventilation continues to evacuate heat, which is considered ventilation without heat.
Once the thermal protection is triggered, you must restart the fan heat to resume normal operation:
1. Find the cause of the overheating and eliminate it. For instance, make sure no objects are blocking the air inlets and outlets and
that they are clean.
2. Make sure the fan heater has not suered heat damage.
3. Switch o the power supply to the fan heater directly from the electrical panel.
4. Wait ten minutes, then turn the power back on.
If the fan heater doesn’t begin heating again after a restart, it means an internal component may be defective, or an additional thermal
protection device has been triggered. In this case, contact STELPRO's customer service department.
