2. When the external control is activated, the wall furnace dis-
play panel will illuminate and show the heat level along with
the remote signal symbol. The wall furnace will begin the

Notice: When a Millivolt thermostat or on/off switch is used, the
wall furnace will only operate on high (Level 5).
Notice: When operating in Remote mode, a button sequence
may be used to lock the display panel. See page 12.
3. If a Millivolt thermostat or thermostatic remote is used, set to
the desired room temperature. The wall furnace will turn on
and off automatically in response to the thermostat.

Wall Furnace Operation - Local Mode (Internal Thermostat)
1. To operated the wall furnace in Local (thermostatic) mode,
press the Mode Select button on the wall furnace display
panel three times from the off mode. The display panel will
show the current room temperature. See Figure 8.
Notice: The temperature sensing probe is built into the left rear
of the wall furnace. A kit to relocate the probe is available. See
page 15.
2. Use the up and down adjustment buttons on the display
panel to set the desired room temperature.
The display will illuminate and the word "SET" will appear
in the top right corner of the display. See Figure 9. After the
temperature is set, the display panel will darken and return
to displaying the room temperature.
3. When the room temperature drops to 3°F below the set tem-
perature, the wall furnace will begin the start up sequence.
4. The wall furnace will automatically adjust the starting level to
meet the heat demand.
Notice: The greater the difference between the room and de-
sired temperatures the higher the starting level.
As the room temperature nears the desired temperature the
level will decrease.
5. The wall furnace will turn off if the room temperature rises
slightly above the set temperature when operating at level 1.
Notice: The wall furnace will adjust the heat level in order to
reach a point of equilibrium between the room and desired tem-
peratures. This may cause the wall furnace to operate for long
periods of time at low levels.
When the backlight button is pushed, the display will cycle be-
tween the level, set temperature and room temperature.
Notice: While the wall furnace is operating in Local mode, the
display will only show the room temperature unless the backlight
button is pushed.
