Read This Before Installing Thermostat
IMPORTANT
Read the entire installation section of this Owner’s Manual
thoroughly before you begin to install or operate your Cli-
1
mate Technology Thermostat.
INSTALLATION
All installation is normally performed at your
thermostat.
2
ARMCHAIR PROGRAMMING
You can program your thermostat before installation by in-
3
serting the batteries and following the instructions starting
on page 18. This can be done while you relax in your favorite
chair and is a very good way to familiarize yourself with all the
functions of your Climate Technology Thermostat.
SYSTEM COMPATIBILITY
Your Thermostat is designed to operate these
24-Volt systems:
4
■ Multi-stage heat pumps with auxiliary heat
■ Multi-stage systems (2 stage heat, 2 stage cool)
This thermostat will not control 120/240 Volt systems or
millivolt systems.
COMPRESSOR PROTECTION
The thermostat provides a 3.5 minute delay after shutting off
the heating or cooling system before it can be restarted.
5
This feature will prevent damage to your compressor caused
by rapid cycling.
TEMPERATURE RANGE
Your thermostat can be programmed between 45°F and 95°F
(7°C and 35°C). However, it will display room temperatures
6
from 15°F to 99°F (-9°C and 37°C). “HI” will be displayed if
the temperature is higher than 99°F (37°C), and “LO” will be
displayed if the temperature is lower than 15°F (-9°C).
AUTO RECOVERY
Your thermostat is set from the factory to gradually recover
7
the room temperature from an energy saving program to
your comfort program. Therefore, the thermostat may turn your
system on several minutes prior to your programmed time. This
operation is normal, but can be turned off. Refer to the Options
Menu information on pages 18-21.
6
7
OPERATION
This system operates on your system’s 24 Volt power supply.
The supply is monitored by the thermostat, and it will stop
8
functioning if AC power is lost. (When using backup batteries,
“No AC Pwr” will be displayed.) All system controls will remain
off until power is restored.
The INDIGLO® Night-Light will not function when
NOTE:
AC power is lost.
NOTE:
Any remote temperature sensors (if used on your
system) will not operate when AC power is lost.
BATTERY WARNING
Batteries may be used optionally to prevent the loss of your
thermostat’s clock, programs and options due to a power
9
outage. However, when the batteries become drained, a low
battery warning will appear on the display. When this message
occurs, install 2 new AAA batteries. You have approximately 30
seconds when changing the batteries to keep thermostat’s
clock and program settings.
The default system selection at power-on is HEAT.
NOTE:
Batteries are recommended to prevent an undesired system change due to a power outage.

INSTALLATION
What You Need
This thermostat includes two #8 slotted screws and two wall anchors for mounting. To install your thermostat, you should have
the following tools and materials.
Selector Switches
In order for this Climate Technology thermostat to control your
system, the system type must be specified by selector switch
on the rear inside if the thermostat. There are also other selector switches that allow you to customize the features to suit
your needs. Refer to Figure 2 for removal of wallplate.
When changing these features after installation,
NOTE:
move the power switch to OFF before removing the thermostat from the wall.
■
Slotted Screwdriver(s)■Electric drill and 3/16" bit
■
Phillips Screwdriver
■
Hammer
■
Two 1.5 V (AA) size alkaline batteries
System Selector Switches:
■
Heat Pump or Multi-Stage selector (HP-MS switch)
The factory position for this switch is in the “HP” position.
Leave it in this position if you have a heat pump system or
need emergency heat control.
If you have a conventional multi-stage system (more than 1
stage of heat or cool), then slide the switch to the “MS”
position.
The Emergency Heat Function operates both
NOTE:
stages of heat at the same time when in multi-stage
mode.

Selector Switches (continued)
■
Heating system selector (HG - HE switch)
The factory position for this switch is in the “HG” position. Leave it
in this position if you have a gas furnace or an oil burner.
If you have an electric furnace, test to see whether the Heat
and Fan come on as expected.
If Fan operation is normal, leave the switch in the “HG” position.
If the Fan does not come on within a minute of the thermo-
stat calling for Heat, change the switch position to “HE.”
This selector has no effect in the cooling mode.
“HG” position is for gas and most other systems.
NOTE:
“HE” position is for certain electric systems having a
fan relay.
NOTE:
This option is ignored when heat pump (HP) sys-
tem is selected.
■
Low Battery Warning Selector
This Climate Technology thermostat operates on your system’s
24V AC supply. Two AAA batteries may be installed to provide
clock operation and program retention during power outages.
The factory position for this switch has the Low Battery Warning Enabled. If the thermostat is to be used without batteries,
the switch can be moved to Disable. In this position, the Low
Battery Warning will not be displayed.
Climate Technology recommends that the Low Battery Warning be activated by sliding the switch to Enable, especially on
residential systems.

INSTALLATION
Remove Old Thermostat
CAUTION:
mostat before reading the instructions carefully. WIRES
MUST BE LABELED PRIOR TO REMOVAL.
■
■
If wires are not visible, they may be connected to the back of
the wallplate. Again, look for screws, tabs, etc. Some models
have doors that open to expose wires and mounting screws.
(See Figure 1).
Do not remove any wiring from existing ther-
IMPORTANT! Turn off the power to the furnace at the main
power panel or at the furnace.
Remove existing thermostat cover. See Figure 1. Some thermostats will have screws or other locking devices that must
first be removed. Once wall mounting plate is exposed, look
for wires.

Wire Labeling
■
Each wire coming from the wall to the existing thermostat is
connected to a terminal point on that thermostat. Each of
these terminal points is usually marked with a code letter as
shown in Table A below and on the next page.
■
The number of wires in your system can be as few as four
(for single-stage systems), as many as eight, or any number
in between. If you follow the labeling procedures correctly,
you do not have to be concerned about how many wires
there are.
■
IMPORTANT! BEFORE DISCONNECTING ANY WIRES, APPLY
THE SELF-ADHESIVE LABELS PROVIDED TO THE WIRE AS
TABLE A – TERMINAL DESCRIPTIONS
TERMINAL FUNCTION FUNCTION
LABELS (HEAT PUMP MODE) (MULTI-STAGE MODE) COMMENTS
R 24VAC supply 24VAC supply Hot wire of 24VAC transformer. Powers the thermostat & system.

W2 Auxiliary heating Heating stage 2 Activates when auxillary heating is required on heat pump systems.
SHOWN IN TABLE A and B ON PAGES 13-15. (For example,
attach the label marked W to the wire that goes to the W or H
terminal on your existing thermostat.) IGNORE THE COLOR OF
THE WIRES since these do not always comply with the standard.
■
After labeling wires, disconnect them from the existing thermostat terminals.
■
Remove existing wallplate. To make sure wires do not fall back
into wall opening, you may want to tape them to the wall.
■
If hole in wall is larger than necessary for wires, seal this hole
so that no hot or cold air can enter the back of the thermostat
from the wall. This air could cause a false thermostat reading.

■
Remove the wallplate from your thermostat by pressing the
release tab on the bottom of the thermostat. (See Figure 2.)
■
Position wallplate on wall and pull existing wires through
large opening. Then level for appearance. Mark holes for plastic anchors provided if your existing holes do not line up with
those on the Climate Technology wallplate.
Figure 2 Figure 3
■
Drill holes with 3/16" bit and gently tap anchors into the
holes until flush with wall.
■
Reposition wallplate to wall, pulling wires through large
opening. Insert mounting screws provided into wall anchor
and tighten. (See Figure 3.)

Connect Wires and Mount Thermostat Cover to Wallplate
■
Straighten bare end of each wire and cut or strip it to 1/4”
maximum. Insert each labeled wire into the bottom of the
maching terminal. Refer to figures 4 and 5.
■
Hold the wires in each terminal and tighten the terminal
screws securely, otherwise a loose wire could cause operational problems with your system or thermostat.
■
Push excess wire back into hole to prevent interference with
mounting of the thermostat.
■
Make sure the Power Switch is set to OFF.
■
Insert two AAA size alkaline batteries, observing the polarity
marked on the unit.
■
Insert the upper tabs on the thermostat body into the slot at
the top of the wallplate. Press bottom of the thermostat body
to snap it into the wallplate. (NOTE:
mostat onto the wallplate, as the terminal pins may be
damaged. If it does not snap properly, the thermostat
may not work.
