BLOWER SPEED
One of the best ways to control the temperature is by
changing the speed of the blower. The blower knob (left
of center) provides four speeds in any mode, except when
the control is set to OFF.
TEMPERATURE CONTROL
The center knob controls the temperature of the
discharged air. Turn the knob to the right (red area) for
warmer air, and to the left (blue area) for cooler air.
MODE
To achieve the maximum comfort in your coach, the air
must be directed where it is needed. The mode switch
(right of center) gives the driver the ability to select where
the air will flow. The air conditioning system is designed to
operate in all modes except VENT, FLOOR, and OFF. This
provides significant moisture, dust and pollen removal for
enhanced passenger comfort.
This chapter provides operational instructions for components related to dash and roof air conditioning, fans
and ventilation, heating systems, and climate control.

Dash Air Conditioning and Heat Controls and Settings
Controls and Settings
The article provides a basic overview for the dash air conditioning and heat controls and settings. The dash air
conditioning control panel enables the driver to control the temperature, volume, and direction of the air discharged from
the heating/air conditioning system. Select coach models may have a driver and passenger control with a switch that
allows the driver to override the passenger controls.
If the mode knob is in any position other than OFF,
the blower is always on a low speed unless a higher
speed is selected.

Any of the following quick start instructions provided by Newmar should not take the place of the manufacturer’s
complete documentation. Refer to Newgle for more information about heating, ventilation, and air conditioning
components offered for your coach’s model year.
MAX A/C OR A/C RECYCLE BUTTON
Air is drawn from the passenger compartment and is
discharged and recirculated through the dash louvers.
This position is used to provide maximum cooling, and is
generally used during extremely hot weather conditions
for initial cool-down periods. Because this mode does not
allow fresh “outside” air into the passenger compartment,
it may cause fogging of the windows, and/or stale air,
when used for prolonged periods of time. Switch to A/C
mode periodically if these conditions occur.
A/C OR SNOWFLAKE BUTTON
Outside/fresh air is drawn into the system and
discharged through the dash louvers. These louvers can
be adjusted for maximum comfort.
VENT
Outside air is drawn into the system and discharged
through the dash louvers. For enhanced passenger
comfort, upper-level ventilation air is also discharged
through the defrost outlets. When outside ambient
temperatures are below approximately 40° F, the A/C
compressor may cycle rapidly. Use Vent mode instead of
A/C in these temperature conditions to cool the interior
air temperature.
