Analog Thermostat
There are 3 different Analog thermostats being used to
control Duo-Therm Air Conditioners, Air Conditioners with
Heat Strips, and Heat Pumps. The type of Thermostat used
depends on the unit and accessories used with it.
It is very important for the proper location of the Analog
Thermostat to ensure that it will provide a comfortable RV
temperature (See Section A7. Thermostat Location). Ob-
serve the following rules when selecting a location:
1. Locate the Analog Thermostat 54" above the floor.
2. Install the Analog Thermostat on a partition, not on an
outside wall.
3.
Never expose it to direct heat from lamps, sun or other
heat producing items.
4. Avoid locations close to doors that lead outside,
windows or adjoining outside walls.
5. Avoid locations close to discharge registers.
The Analog Thermostat is mounted on the wall of the RV
and is connected to the Analog Control Box with 6 or 7
wires depending on the Unit and accessories being used.
Current Model Color Coding
1. Connect the previously run +12V DC to the red wire
l12V protruding from the relay kit.
2. Connect the previously run -12V DC to the black wire
labeled -12V protruding from the relay kit.
3. Connect the red/white wire to the ther7.5.
4. Connect the unit green wire to the thermostat GND
terminal.
5. Connect the unit yellow wire to the thermostat COOL
terminal.
6. Connect the unit tan wire to the thermostat FAN termi-
nal.
7. Connect the unit blue wire to the thermostat HI FAN.
8. Connect the unit orange wire to the thermostat HS/HP
terminal (if applicable).
9. Connect the unit white wire to the thermostat FUR ter-
minal (if applicable).
10. Connect the unit blue/white wires to the two furnace
