6. For total automation, select AUTO, which will turn
on the air conditioner(s) or if needed, the furnace
depending on selected temperature setting.
7. Return to the MAIN MENU by touching the ‘House-
shaped’ icon on the panel or touching return arrows
on the screen.
Wall-mounted Thermostats
Unless equipped with a multiplex control system, your
TMC motorhome will have a wall-mounted thermostat
for convenient control of the heating and air conditioning
functions. Although different in appearance, RV thermo-
stats offer the basic functions of:
• Selecting between Heat, Cool, or Fan Only
• Selecting a fan speed range
• Selecting the temperature set point
The thermostat remotely operates both the furnace and the
air conditioner(s) of your motorhome and depending on
thermostat model, may offer other control features. Wall
mounted thermostats may be analog or feature a digital
display. Both models operate similarly. If your air condi-
tioning units are equipped with the optional Elect-A-Heat
function, this selection will be indicated as electric heat on
the front of the thermostat.
TO OPERATE:
1. Turn ON the Master Battery Disconnect Switch, pro-
viding 12 volt DC power to the HVAC control unit(s).
a. If heat is desired, ensure the main propane valve is
ON prior to selecting HEAT.
b. If cooling is desired, ensure 120 volts AC is available
for the air conditioner(s).

2. On the thermostat, select Heat, Cool, or Auto.
3. Set the desired temperature. Depending upon the
selection, the furnace or air conditioner(s) will begin
operation.
If a wall-mounted thermostat or multiplex system is not
installed in the motorhome, then air conditioner functions
are controlled from a panel on the unit itself (ceiling panel).
NOTE: For complete information regarding the par-
ticular HVAC control device installed on your motor-
home, refer to the information contained with your
TMC Owner’s Packet, supplied with your motorhome.
Ceiling and Ventilation Fans
Your vehicle may be equipped with high-volume ceiling
and ventilation fan(s). If equipped, the fan(s) can be oper-
ated as a powered vent; to draw in cool outside air, or as
a ceiling fan to circulate the inside air of the motorhome.
Fans are usually equipped with a translucent rain cover,
which can be opened, partially opened, or closed.
Refer to the TMC HVAC System Guide for complete
operational and maintenance instructions pertaining to
motorhome ventilation and fan operation. Also, refer
to the Care and Maintenance Section of this manual for
important condensation information.
Cooling the Motorhome
Your motorhome is equipped with one or more
roof-mounted air conditioners. Select motorhomes are
equipped with roof-mounted heat pumps (air conditioners
with built-in heating features), while other motorhomes may
feature a combination of roof-mounted and wall-mounted
air conditioning units. The compressors and fans of all
roof-mounted air conditioners operate on 120 volts AC,
supplied by shore power or from the on-board generator,
