ADVANCED FEATURES
SAFETY CONSIDERATIONS
Improper wiring or installation may damage controller. Wiring must
conform to local and national electrical codes
INTRODUCTION
The controller is a wall mounted, 24VAC low-voltage controller 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 controller requires no batteries. The controller is not a power stealing
device and MUST have both R and C connected.
INSTALLATION
IV. CONTROLLER LOCATION
Controller 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.
Controller 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.
V. INSTALL CONTROLLER
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.
6. Secure back plastic to wall with 2 anchors and screws provided making
sure all wires extend through hole in plastic.
7. Use minimum of 22-gauge wiring, 18-gauge is recommended, for basic
controller wiring. Shielded twisted pair should be used for optional remote
indoor and outdoor sensors. Connect wires to proper terminal of the
connector block in the front plastic.
8. Push any excess wire back into wall. Excess wire inside the controller
plastic case can interfere with proper air flow across the temperature
sensor. Seal hole in wall to prevent air leaks. Leaks can affect operation.
9. Snap front and back pieces of plastic together.
10. Turn on power to the unit.
VI. INSTALLER SETTINGS
NOTE: These options are intended to be used by the installer. End users
are not advised to change or modify any of these settings. Doing so may
make your equipment stop working properly and/or may void the warranty
of the controller as well as the equipment hooked up to the controller. To
access the installer setting menu, the mode must be set to OFF. Then, press
both the up and down arrows keys at the same time for at least 5 seconds to
enter the installer screen.
