Climate Control System

All controls for the heating/cooling climate control system are incorporated into thetouch
screen system. For specific operating instructions for heating/cooling controls, refer to the-
touch screen user guide included in your warranty packet or online at
com.
The air conditioner/heat pump heats and cools from a single unit. The heating unit will not
replace a furnace for heating your motor home in cold weather. It is designed to warm the
coach during cool or mild temperatures. Both the heating and cooling unit are controlled by
a single thermostat which is controlled through the Vegatouch screen.
In the cooling mode, the temperature drop from inlet to supply will be 15 to 20 degrees. In
the heating mode the temperature rise from inlet to supply will be 25 to 40 degrees unless
the outdoor temperature has dropped sufficiently to cause the freeze switch to activate. In
that case, the rise will be only 10 to 20 degrees. Any deviations from these norms are cause
to examine the system for dirty air filters or outdoor coil.
Parking the vehicle in a shaded area, keeping windows and doors shut and avoiding the use
of heat producing appliances in the vehicle will help to reduce the heat gain.
Do not operate the heat pump for extended periods of time without the filter
installed. Lint, grease, dirt, etc. that are normally stopped by the filter are now
accumulating in the cooling coil. This leads to loss of air volume, icing up of
the cooling coil, and could result in serious damage to the operating compo-
nents of the heat pump.
Maintenance
The only required maintenance on the heat pump is cleaning and replacing the filters. The
filters can be cleaned and reused. It is recommended that filters be cleaned and changed at
least every 2 weeks when the heat pump is in operation. Refer to the manufacturer's owner's
manual for additional information on changing the filter.
Power Vent Fans
The power vent fans may also be controlled by thetouch screen system. These fans can be
located in the kitchen and bathrooms. For further information refer to the manufacturer's
owner manuals for each of the power vents for specific features.

Power Roof Vent (if so equipped)

The 12-volt DC attic fan (or powered roof vent) allows fresh air to circulate through the
recreational vehicle. Do not leave the attic fan open when the recreational vehicle is stored
or unattended for long periods.
High winds, other unusual conditions or obstructions may prevent the dome from closing;
the resulting leakage could cause non-warrantable damage.
To use your fan most effectively, close all vents and slightly open a window on a shaded side
of your recreation vehicle. You are directing the air flow by opening a window.
For additional safety and operating information refer to the manufacturer's owner's
manual.
