INTRODUCTION
The thermostat is a wall mounted, low-voltage thermostat which maintains room
temperature by controlling the operation of a heating and air conditioning
system. Batteries are not required; temperature and mode settings are preserved
with the power off.
INSTALLATION CONSIDERATIONS
The thermostat requires no batteries. The thermostat is not a power stealing
device and MUST have both R and C connected.
INSTALLATION
III.
THERMOSTAT LOCATION
Thermostat should be mounted:
- Approximately 5 ft. (1.5m) from floor.
- Close to or in a frequently used room, preferably on an inside
partitioning wall.
- On a section of wall without pipes or duct work.
Thermostat should
NOT
be mounted:
- Close to a window, on an outside wall, or next to a door leading
to the outside.
- Exposed to direct light and heat from a lamp, sun, fireplace, or
other temperature-radiating object which may cause a false reading.
- Close to or in direct airflow from supply registers and return-air grilles.
- In areas with poor air circulation, such as behind a door or in an alcove.
IV.
INSTALL THERMOSTAT
1. Turn off all power to unit.
2. If an existing thermostat is being replaced:
A. Remove existing thermostat from wall.
B. Disconnect wires from existing thermostat, one at a time. Be
careful not to allow wires to fall back into the wall.
C. As each wire is disconnected, record wire color and terminal marking.
D. Discard or recycle old thermostat.
NOTE:
Mercury is a hazardous waste and MUST be disposed of properly.
3. Separate the front and back pieces of plastic.
4. Route thermostat wires through hole in back piece of plastic. Level plastic
against wall (for aesthetic value only - thermostat need not be leveled for
proper operation) and mark wall through 2 mounting holes.
5. Drill two 3/16-in. mounting holes in wall where marked. (Note: Mounting
holes on thermostat are designed to fit on a horizontal J-box).
6. Secure back plastic to wall with 2 anchors and screws provided making sure
all wires extend through hole in plastic.
7. Connect wires to proper terminal of the connector block in the front plastic.
8. If an outdoor sensor is to be installed, run the sensor wires from the desired
outdoor location to the OD and GND terminals on the connector block.
9. Push any excess wire back into wall. Excess wire inside the thermostat
plastic case can interfere with proper air flow across the temperature sensor.
Seal hole in wall to prevent air leaks. Leaks can affect operation.
10. Snap front and back pieces of plastic together.
11. Turn on power to the unit.
WIRING DIAGRAMS
All excess wire should be pushed back into the wall as far as possible. Excess
wire inside the thermostat plastic case may interfere with the air flow across the
temperature sensor.

WARNING:
Before installing thermostat, turn off all power to unit. There
may be more than one power disconnect. Electrical shock can cause personal
injury or death.
