Resetting the Manual Power Reset Limit Control
Warranty
How to operate your heater
The room temperature is controlled by a line voltage thermostat
located either on the wall, or at the lower left on the heater (See
Page 1; In-built Thermostat).
1. Once installation is complete and power has been restored,
turn the thermostat knob fully clockwise.
2. When the room reaches your comfort level, turn the thermo-
stat knob counterclockwise until the heater turns off. The heater
will automatically cycle around this preset temperature.
3. To reduce the room temperature, turn the knob counterclock-
wise. To increase the room temperature, turn the knob clockwise.
Over Temperature-Limiting Controls
If normal operating temperatures are exceeded (due to abnormal
circumstances), the heater has two temperature-limiting controls
(for Model CST, four controls are used). Both limiting controls are
located on the element assembly. The rst is a manual power
reset limit control, designed to open the heater circuit when ex-
cessive operating temperatures are detected. The problem must
be assessed and the limit must be reset to resume operation.
Further protection is provided by a secondary over-temperature
fuse, which will open the heater circuit in severe over-tem-
perature conditions, or in the event of component failure. If this
occurs, the heater must be repaired or replaced.
If the manual power reset limit has opened the heater circuit due to excessive operating temperatures, the heater will not
work until it is reset. This can be done at the thermostat or the circuit breaker controlling the heater.
1. Lower the temperature on the thermostat below room tempera-
ture.
2. Allow the unit to cool for at least 20 minutes.
3. Resolve the problem causing the limit to trip (typically the heat-
er is blocked or needs cleaning, see Maintenance Instructions).
4. Raise the temperature on the thermostat back above room
temperature. The heater should come back on. If it does not come
back on, reset heater at the circuit breaker, using directions below.
An additional 20 minute waiting period is required every time the
power is turned off. Restoring power, even briey, will heat the
limit even though the heater does not come on.
5. The heater is now functional and the thermostat can be reset to
your comfort level.
1. Trip the breaker by switching it to the OFF position.
2. Allow the unit to cool for at least 20 minutes.
3. Resolve the problem causing the limit to trip (typically the heat-
er is blocked or needs cleaning, see Maintenance Instructions).
4. Restore power to the heater by switching the breaker to the
ON position.
5. Raise the temperature on the thermostat above room tempera-
ture. The heater should come back on. An additional 20 minute
waiting period is required every time the power is turned off.
Restoring power, even briey, will heat the limit even though the
heater does not come on.
6. The heater is now functional and the thermostat can be reset
to your comfort level.
Note that resetting the manual power reset control may not restore heater operation if a severe over-temperature
condition has occurred. See the Troubleshooting Guide on next page for more information.
