Roof Air Conditioning and Heat Overview
This article provides a brief overview of the roof air conditioning and heat pump, as well as filter maintenance. Keep your
coach comfortable year around! Your coach’s air conditioners can be operated using the Comfort Control thermostat, KIB
V-Bus LCD touchscreen, or the appropriate SilverLeaf screen. For more detailed information about climate control, refer to
the appropriate product page(s) and associated content in Newgle.
Some roof top air conditioners have the ability to work as a heat pump when desired to produce heat instead of cooling.
These models are e
ff
ective at producing heat at ambient temperatures (above approximately 40 degrees). If the
temperature drops below the threshold, most controls will revert to the furnace or hydronic heating system to produce the
necessary heat.
Most air conditioning systems have a two minute built-in time delay, so there may be a slight delay in the operation of the
air conditioner after the thermostat is set.
Filter Maintenance
1. Remove the vent cover from the return air duct or air conditioner.
2. Remove the filter.
3. Wash, rinse, and dry the filter. If the filter does not come clean, or is damaged, replace it with a new filter. Do
not substitute other types of filters, as this may restrict air flow and cause other issues. Do not operate the air
conditioners without filters.
4. Reinstall the filter on the cover, and place it back into the vent.
5. Repeat the process for each return air vent.
Air Conditioning and Heat, Roof
OFF
The blower motor does not operate in this mode.
The fresh air inlet door closes, minimizing outside air
infiltration into the vehicle.
BI-LEVEL
Outside air is drawn into the system and discharged
through the dash louvers, floor, and defrost outlets. The
A/C system operates in Bi-level mode.
FLOOR
Outside air is drawn into the system and discharged
through the floor outlets. In some models, a small amount
of air is directed to the windshield for defrost. The a/c
system does not operate while in floor mode.
MIX
Outside air is drawn into the system and discharged
through the floor and defrost outlets. The A/C system
operates in Mix mode to provide windshield defogging.
DEFROST
Outside air is drawn into the system and discharged
through the defrost outlets. The A/C system operates in
Defrost mode to provide windshield defogging.
For operational safety in the event of the loss of
vacuum, the HVAC system is designed to discharge
air through the defrost vents to provide continuous
windshield defogging.

!
Climate Control via SilverLeaf
The Climate All screen controls and displays the settings for the heating and air conditioning (HVAC) system in the
coach. From this screen, you can set the temperature for heating and cooling, as well as schedule temperature changes
by day, night, or when you are away.
Use the Climate All screen to manage the heating and
cooling for all HVAC zones in the coach. This is a global
display and control.

: Display the current status
and operation of the HVAC system in the Climate All
screen or the screen for the selected zone.
