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 Climate Technology Thermostat.
1
INSTALLATION
All installation is normally performed at your
thermostat.
2
ARMCHAIR PROGRAMMING
You can program your thermostat before
installation by inserting the batteries and following
the instructions starting on page 16. 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.
3
OPERATION
Your Thermostat is designed to operate with
most gas, oil, electric or 2-wire hot water heating
and air conditioning systems. It will also operate
single-stage heat pumps that do not have auxiliary
or emergency heat. These have 24-volt or millivolt
control systems and represent most central heating,
air conditioning, or space heating units in use in the
United States.
4
5
This Climate Technology Thermostat will NOT
control multi-stage heat pumps or 110/220
Volt systems.
COMPRESSOR PROTECTION
The thermostat provides a 3.5 minute delay after
shutting off the heating or cooling system before
it can be restarted. This feature will prevent damage
to your compressor caused by rapid cycling. Note
that this delay also applies to the heating system
control. It does not prevent a rapid compressor restart due to short power outages.
5
TEMPERATURE RANGE
Your thermostat can be programmed between
45°F and 95°F (4°C and 35°C). However, it will
display room temperatures from 32°F to 99°F (0°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 32°F (0°C).
6
This thermostat will automatically cut off in Heat
mode if the temperature rises above 95°F (35°C),
and automatically cut off in cool mode if the temperature drops below 45°F (7°C).
Read This Before Installing Thermostat (continued)
POWER FAILURE
Whenever the main power is interrupted or fails,
the battery power retains the programs and current time.
7
AUTO RECOVERY
Your thermostat is set from the factory to gradually
recover 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 Selector
Switches information on page 24.
6
change the batteries and keep thermostat’s clock and
program settings. Once the batteries have become too
low to ensure proper operation, your system will be
turned Off, and the display will be cleared except for
the Low Battery indicator flashing on the LCD display.
8
BATTERY WARNING
Fresh alkaline batteries should provide over one
year of service. However, when the batteries become drained, the Low Battery indicator will flash on
the display. When this message occurs, install 2 new
AA batteries. You have approximately 1 minute to

ENERGY STAR® Partner
As an ENERGY STAR® Partner, Climate Technology has
determined that this programmable thermostat meets
the ENERGY STAR® guidelines for energy efficiency.
CAUTION: Once the Low Battery only display occurs, the thermostat is shut down, and your system will no longer operate. In this condition,
there is no temperature control of your dwelling.
NOTE: The INDIGLO® night-light will not function
when the thermostat is in low battery condition.

CAUTION: Do not remove any wiring from existing thermostat before reading the instructions
carefully. WIRES MUST BE LABELED PRIOR TO
REMOVAL.
TYPICAL HOME THERMOSTATS
Figure 1
■ 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.

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).
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 on the next page.
■ Note that this thermostat has multiple function
terminals that allow Single-Stage Heat Pump capability. Standard systems use: Rh, Rc, G, W.
[Single-Stage Heat Pumps use: Rh, Y1, G, and O or
B.] Table A below shows the multiple functions of
the terminals. Use the terminals that match your
system.
■ The number of wires in your system can be as few
as two (for heat only 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.
■ There is often no terminal marking on the
G Y
existing thermostat of
W
RH
two wire, heat only
RC
systems. Just connect
either of the wires to
the RH terminal, then
connect the other wire
to the W terminal to
complete the circuit.
9
■ IMPORTANT! BEFORE DISCONNECTING ANY
WIRES, APPLY THE SELF-ADHESIVE LABELS PROVIDED TO THE WIRE AS SHOWN IN TABLE A ON
THE NEXT PAGE. (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 with insulating material 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.

Connect Wires and Mount Thermostat Cover to Wall Plate
■ Match and connect the labeled wires to the appropriate coded terminal screws on the wallplate. (See
Figure 4, 5.) Ignore any wires which may be present,
but which were not connected to the old thermostat.
■ Refer to the Wiring Diagrams below to be sure your
system is wired correctly.
■ If your system is a single-stage heat pump and
uses an O or B wire, you must move the System
Selector switch inside the thermostat to the Heat
Pump position. If you have a normal furnace or
electric system, leave the switch in the Standard
position. Refer to the System Selector section on
the back for more information on this switch.
■ Be sure to tighten the terminal screws securely,
otherwise a loose wire could cause operational
problems with your system or thermostat.
■ Push excess wire back into the hole to prevent interference when installing the thermostat to the wallplate.
■ Make sure the System Switch is set to OFF, and the
Fan Switch is set to AUTO.
■ Insert the bottom tab on the thermostat body into
the slot at the bottom of the wallplate. Press the
top of the thermostat body to snap it into the
wallplate. Refer to Figure 6. (NOTE: Do not force
the thermostat onto the wallplate, as the terminal pins may be damaged. If it does not
snap properly, the thermostat may not work.)
■ Insert the two AA size alkaline batteries, observing
the polarity marked inside the battery compartment.
■ Switch on the main power at the panel or furnace.

Selector Switches
In order for this Climate Technology thermostat to
control your system, the system type must be specified by selector switches on the printed circuit board
inside the thermostat.
NOTE: When changing these features after installation, move the HEAT / COOL selector switch to
OFF before removing the thermostat from the
wall.
System Selector Switches:
■ 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 thermostat calling for Heat, change the switch
position to “HE.”
The system selector has no effect in the cooling mode.
NOTE: “HG” position is for gas and most
other systems. “HE” position is for certain
electric systems having a fan relay.
13
■ Furnace or Heat Pump selector (STD - HP switch)
The factory position for this switch is in the STD
position. Leave it in this position if you have ANY
system that uses gas, oil, electric, or hot water heating.
If you have a single-stage Heat Pump (no auxiliary
or emergency heat source), then slide the switch to
the HP position.
■ Auto Recovery selector (DISABLE / ENABLE)
Your thermostat is set from the factory with the Auto
Recovery Feature enabled, which complies with the
EPA ENERGY STAR® Program. If you prefer to use
normal recovery, slide the switch to the ALT position.
Refer to page 32 for a complete discussion of the
Auto Recovery feature.

Auto Recovery
Climate Technology’s Auto Recovery feature meets
the ENERGY STAR® guidelines for energy efficiency
by allowing the heating or cooling system to recover
gradually from an energy-saving setpoint temperature to a comfort setpoint temperature.
For example, in Heat mode, you could have the following programs:
Program #4 (Overnight)
Program #1 (Morning)
Set Temp = 60°F
Set Temp = 68°F
Time = 10pm
Time = 6am
Auto Recovery calculates how early to turn your system back On, so that the room temperature is already
comfortable by the start of the comfort temperature
program period. Auto Recovery works in both Heat
and Cool modes.
The room temperature fell to 60°F overnight. Rather
than having the thermostat turning on at 6am, Auto
Recovery would note the temperature difference between 60°F and 68°F and turn the Heat on approximately 30 minutes early. Therefore, the room temperature at 6am would be about 68°F instead of 60°F.
■ When the thermostat is in Auto Recovery mode, the display will
alternate RECO with time, and the program indicator will flash.

HEAT
TEMP
Details of Auto Recovery Operation:
■ Auto Recovery can be disabled by sliding the Recovery switch on the circuit board to the DISABLE
position. Refer to page 13.
■ Auto Recovery will not operate if Permanent hold,
Temporary hold or Home Today is in operation.
■ Auto Recovery can be canceled manually if HOLD/
RETURN is pressed during the recovery process. If a
recovery process is canceled manually then the recovery process will not start again until the next
program period starts (an exception is that if time
or program is changed then the thermostat will
check Auto Recovery conditions immediately).
33
■ Auto Recovery will be canceled and change to
Home Today mode if HOME TODAY is pressed
during the recovery process.
■ Auto Recovery will be canceled and change to
Temporary Manual Override mode if the setpoint
is adjusted during the recovery process.
■ If the system is changed between heat and cool
then the thermostat will recalculate Auto Recovery again. Setpoint temperature will be changed
to the opposite system’s comfort temperature if
the recovery entry criteria are still met. Otherwise,
the recovery process will be canceled and return
to program control mode.

SPAN Setting Mode
Your thermostat is set at the factory to cycle at
1˚F (0.5˚C) above and below the set temperature.
(Span = 2) This setting has been designed to provide a comfortable room temperature under most
all conditions. However, if you find your system
cycling too fast or too slow, then the Span can be
adjusted to modify the cycle time.
■ Press and hold BOTH for three seconds. The display
will flash, and SPAN will be displayed on the LCD.
■ Press to raise the Span to 3. This setting INCREASES
the cycle time by allowing your system to run
LONGER.
■ Press to lower the Span to 1. This setting
DECREASES the cycle time by causing your
system to run SHORTER.
The Span settings remain the same for both HEAT
and COOL.
The Span can be changed at any time, and is independent of program times or temperatures.
When batteries are installed in the thermostat, or
the Reset key is pressed, the Span is reset back to
setting 2.
Backlighting (INDIGLO® night-light)
Your thermostat has an electroluminescent lamp that
backlights the display for easy viewing in the dark.
When any key is pressed or the System Switch is
changed, the display is illuminated.
The display will remain illuminated for 5 seconds after
the last key is pressed. This allows the light to stay on
if you need to operate several keys.
35
NOTE: If the thermostat is in Low Battery warning condition, the backlight will not operate. Replace with 2 new alkaline batteries to restore the
Backlight function.
SAFETY FEATURES
36
Low Battery Warning
■ Your thermostat has a two-stage low battery warning system.
When the batteries are first detected to be weak, the first stage
low battery warning is indicated by battery symbol flashing on
the LCD display. At your earliest convenience, you need to replace
the batteries with 2 new AA alkaline batteries.
T
PM
3
HEAT
TEMP
■ When the batteries become too weak for normal operation, the
thermostat enters the second stage low battery warning which
shuts down the thermostat. In this condition, “BATT” flashes
alone on the display, and the thermostat will turn your system Off.
Your system will remain shut-off until the batteries are replaced.
NOTE: The thermostat will still keep the current time and your programs in memory until
new batteries are installed. After confirming that new batteries have been inserted, the
thermostat will return to normal operation.
Error Mode
37
■ If the thermostat is unable to control your system due to an unexpected battery problem, the thermostat will enter Error Mode. In
this condition, the thermostat flashes “Err” on the LCD display, and
shuts off your system. To correct this problem, replace the batteries
with 2 new AA alkaline batteries, even if you have recently replaced
them. Next, use a paper clip to press the RESET button next to the
keypad. You will need to reprogram your thermostat and confirm
normal operation.
■ If Error Mode returns, please call Climate Technology Technical
support at 1-800-676-7861 for further information.
Auto Cut Off
Your thermostat will automatically cut-off in Heat
mode if the room temperature rises above 95˚F (35˚C).
It will cut-off in Cool mode if the room temperature
drops below 40˚F (4˚C).
NOTE: If your system has malfunctioned and no
longer responds to thermostat controls, the Auto
Cut-Off will have no effect.
Mechanical Heat Back-Up
This thermostat includes a bi-metal switch that will
automatically turn on the Heat when the temperature
reaches about 41° F (5°C).
WARNING: This switch only activates
the Heating terminal (W). The system
itself must be capable of automatically
turning the Fan On. Without normal Fan
operation, severe damage to the heating system could result.
