OPERATION
The display indicates room temperature and the word ROOM is shown on the
LCD until the temperature selector is pressed; at which time the display
temporarily indicates the setpoint temperature and the word SET is shown on
the LCD. Each time the UP arrow is pressed, the setpoint will increase. Each
time the DOWN arrow is pressed, the setpoint will decrease. Once the
temperature selector button is no longer pressed for a few seconds, the room
temperature will again be displayed, and the word ROOM will be displayed on
the LCD.

APPLICATION
The 6636-345 thermostat is a heat/cool model wall thermostat.
The thermostat wiring is factory installed by the OEM (Original Equipment Manu-
facturer). Recreation Vehicle Products suggests the thermostat wiring be minimum
18 gauge. The 6636-345 may also operate any RV furnace 12 VDC control circuit
not exceeding one amp. The thermostat is equipped with a replaceable fast-acting
2 amp fuse located on the base of the thermostat. The fuse is designed to “open”
if the furnace is mis-wired or there is a short in the system. Before replacing fuse,
the cause of the failure must be located and corrected.
INSTALLATION INSTRUCTIONS
BE SURE ALL ELECTRICAL POWER HAS BEEN DISCONNECTED FROM
THE AIR CONDITIONER AND THE POWER SUPPLY.
These instructions are provided for the proper mounting of the thermostat itself.
An Operation Chart is provided to show thermostat capabilities.
A. THERMOSTAT LOCATION
This thermostat is a sensitive instrument. For accurate temperature control
and comfort, the following considerations should be taken into account:
1. Locate the thermostat on an inside wall about five feet above the floor. Pick
a dry area where air circulation is good.
2. Do not install the thermostat where there are unusual heating conditions;
such as direct sunlight, heat producing appliances (television, radio, wall
lamp, etc.) or a furnace or air conditioner supply register.
