b.Install the Comfort Control Center™ on a partition, not on an outside wall.

c.NEVER expose it to direct heat from lamps, sun or other heat producing items.

d.Avoid locations close to doors that lead outside, windows or adjoining outside walls.

e.Avoid locations close to supply registers and the air from them.

2.If the system is to be used WITH a Remote Tem- perature Sensor in ALL zones, the Comfort Control Center may be mounted anywhere that is convenient

in the coach. Try to avoid hard to reach and hard to see areas.
