INFORMATION / ADVANCED FEATURES
SAFETY CONSIDERATIONS
Improper wiring or installation may damage thermostat. Wiring must
conform to local and national electrical codes
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
IV.
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.

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. 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.
9. Snap front and back pieces of plastic together.
10. 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.

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
thermostat as well as the equipment hooked up to the thermostat. 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.
MODEL CONFIGURATION
Options to select from:
PROGRAMMABLE / NONPROGRAMMABLE,
SINGLE STAGE/MULTI STAGE
Single Stage
– Used with heat pumps with PSC motors
Multi Stage
– Used with heat pumps with ECM motors, either Single
Speed or Dual Capacity
NORMAL/DUAL FUEL/INTELLIZONE STANDARD/ INTELLIZONE NO
DOWN STAGING
Normal
– used for normal operation
Dual Fuel
– used on dual fuel systems Needs outdoor sensor to
lockout dual fuel.
Intellizone Standard
– used with Intellizone. The ‘W’ acts like a Y3
and requires less droop. It activates 3
rd
stage with the same
time/temperature weighting as Y1 and Y2.
Intellizone No Down Staging
– used with Intellizone and if used,
SHOULD BE ONLY ON MAIN ZONE. The thermostat will hold
the deepest call encountered and should minimize compressor speed
changes.
ACCESSORIES
Each of these options has settings for Cumulative Run Time and Calendar
Time. Messages will flash at the top of the Main screen when these events are
met to alert the owner that it is time service these options.
