In the furnace mode (FURN)
If the desired temperature is above the interior temperature
the furnace will engage and warm the coach to the desired
temperature. At the desired temperature the furnace
will cycle off. If the temperature drops below the desired
temperature the furnace will cycle back on. Ensure that the
propane switch on the exterior of the coach is in the ON
position.
NOTE: Ensure that the fan speed on the right side of the
red and blue arrow is set to FAN AUTO. If there is 110 volt
available and the fan is left on high or low, the fan in the AC
will engage during the furnace mode.
In the VENT mode
If the desired temperature is below the interior temperature,
the roof vent fan will open and the fan will engage. The fan will
run at high speed until the interior temperature reaches the
desire temperature. When the interior temperature reaches
the desired temperature the fan will shut off, however the vent
lid will remain open. The fan will cycle off and on to keep the
desired temperature.
In the A/C mode
110 volt power from a shore line or from the generator must
be present to activate the air conditioner. In the A/C mode
if the desired temperature is below the interior temperature
the roof top A/C will engage to cool the interior of the coach.
The FAN HIGH, FAN LOW and FAN AUTO are used to control
the air conditioner fan speed. If the FAN HIGH or FAN LOW is
chosen the air conditioner fan will continue to run while the air
conditioner compressor will cycle on and off.
If FAN AUTO is chosen the air conditioner fan will cycle
on and off a short time before, and a short time after the
air conditioner compressor engages, to keep the desired
temperature.
NOTE: The FAN HIGH, FAN LOW and FAN AUTO are used to
control the air conditioner fan speed only. These controls
will not affect the roof vent or the furnace fan speeds.
