FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL AND SYSTEM
COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.
Introduction to Thermostat and Communicating
System
The system consists of a premium indoor furnace or air handler, an outdoor AC
condensing unit or heat pump and touchscreen thermostat that is the HVAC command
center. All these devices are linked together and communicate using ClimateTalk
language protocol. The benefi ts of ClimateTalk are auto-confi guration of the system,
the ability to share information throughout the system for enhanced diagnostics and
control, and straightforward wiring since communications requires attaching only four
wires. This ensures simple, reliable operation and an accurate installation.
WARNING
Thermostat installation and all components of the control system
shall conform to Class II circuits per the NEC code.
WARNING
To prevent electrical shock and/or equipment damage, disconnect
electric power to system at main fuse or circuit breaker box until
installation is complete.
ATTENTION: MERCURY NOTICE
This product does not contain mercury. However, this product may replace a product
that contains mercury.
Mercury and products containing mercury must not be discarded in household
trash. Do not touch any spilled mercury. Wearing non-absorbent gloves clean up any
spilled mercury and place in a sealed container. For proper disposal of a product
containing mercury or a sealed container of spilled mercury, place it in a suitable
shipping container.

This document provides information for installation of the touchscreen thermostat
only. Installation instructions of the furnace or air handler and outdoor AC
condensing unit or heat pump are provided with each of these devices.
This thermostat is designed exclusively for this Comfort Control2 SystemTM
equipment ONLY.
Battery Location
2 “AA” alkaline batteries are included
2 "AA" Batteries
in the thermostat to keep time during a
power outage. They are also required
for armchair programming.
If “LOW BATTERY” is displayed in the
scrolling area, the batteries are low and
should be replaced with fresh batteries.
For best results use premium brand
alkaline batteries, such as Duracell® or
Energizer®.
To replace batteries, set thermostat SYSTEM touch key to Off, remove thermostat
from wall by grasping the top and bottom of the thermostat and pulling straight
away from the wall. The base will remain on the wall. Install the batteries in the
rear along the top of the thermostat. Reposition the thermostat over the base
plate and gently snap into place.
Wiring Requirements
Each communicating device in the system has a four wire connection labelled (R,
C, 1, 2). Each R, C, 1, and 2 terminals must be wired consistently.

Quick Install Steps
• Determine location of thermostat installation.
• Mount thermostat base to wall.
• Connect wires to thermostat base.
• Remove battery tag to provide battery power to the thermostat.
• Attach thermostat to base.
• Turn on power to system. Allow approximately 1 minute for the system to
confi gure.
• Set the time
• Select thermostat operating options in the Thermostat Options Confi guration
Menu.
• Perform thermostat/system operation checkout.
• Program thermostat or accept factory programming.
• Touch Run Schedule.
Installing thermostat
• Pull the thermostat body off the thermostat base. Forcing or prying thermostat
will cause damage to the unit.
• Place base at installation location and mark mounting hole locations on wall
using base as a template.
• Move base out of the way. Drill mounting holes.
• Attach base snugly to wall using two mounting screws. Levelling is for
appearance only and will not affect thermostat operation.
• Connect wires to terminal block on base.
• Push excess wire into wall and plug hole with a fi re resistant material (such as
fi berglass insulation) to prevent drafts from affecting thermostat operation.
• Remove battery tag to provide battery power to thermostat.
• Carefully line the thermostat up with the base and snap into place.

Initial Power-Up Advanced Installer Confi guration Menu
Power Up
Turn on AC power to the system. The thermostat will automatically identify the
communicating components installed.
Messages at Thermostat
During power up, the thermostat will
scroll the word “SEARCHING” in
the message area, indicating that the
system is looking for components
(Air Handler, Furnace, Heat Pump,
Air Conditioner) on the Climate Talk
network. Once the components are
identifi ed the message display will
indicate the components found.
Confi rmation will be given in the
message area that the equipment
has been found with the message
(equipment) FOUND.
Note: If the thermostat display continuously shows “SEARCHING”, check the
wiring to the thermostat.
Communications Systems
The thermostat will recognize the
system devices that are connected and
the capacities to set the system up to
the operating settings. The system has
additional fl exibility which allows for the
customization of certain parameters.

the humidity %. If the current humidity
is above the selected setting, the
thermostat will send an On Demand
Dehumidifi cation request.
On Demand Dehumidifi cation improves
the comfort level in your home by
reducing the humidity level. This is
accomplished by slowing down the
