Read the entire installation section of this Owner's Manual
thoroughly before you begin to install or operate your
Thermostat.

WINDOW.

INSTALLATION

All programming is normally performed at your
thermostat's location.
COMPRESSOR PROTECTION
The thermostat provides a 4-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 provide a delay
when there are power outages. You can select the function
ON or OFF during the configuration.
TEMPERATURE RANGE
This thermostat can be programmed between 45ºF and
95ºF (7ºC and 35ºC). However, it will display room tempera-
tures from 30ºF to 99ºF (0ºC and 37ºC). HI will be displayed
if the temperature is higher than 99ºF (37ºC), and LO will be
displayed if the temperature is lower than 30ºF (0ºC).This
thermostat will automatically shut down in Heat mode if the
temperature rises above 95ºF (35ºC), and automatically shut
down in cool mode if the temperature drops below 45ºF
(7ºC).
352-00021-002 Rev A
NOTE: If the thermostat measures a temperature over
99ºF(37ºC), HI will be displayed on the LCD If the tempera-
ture is below 32ºF(0ºC), LO will be displayed on the LCD.
POWER FAILURE
Whenever the main power is interrupted or fails, the
battery power retains the current time for approximately one
minute. This thermostat has permanent memory, although
you will have to reset your clock when there are power
outages of longer duration than one minute.
POWER SUPPLY
The thermostat is powered by 24 VAC, with batteries
providing backup.
BATTERY WARNING
Fresh alkaline batteries should provide about one year of
service. However, when the batteries become weak, BATT
will alternate on the display with the current time. When this
message occurs, install 2 new AA batteries. You have
approximately 1 minute to change the batteries and keep
thermostat's clock. Once the batteries have become too
weak to ensure proper operation, your system will be turned
off, and the display will be cleared except for BATT flashing
on the LCD display.
CAUTION: Once the BATT display occurs, the thermostat
is shut down, and your system will no longer
operate. In this condition, there is no temperature
control. NOTE: The backlight will not function
when the thermostat is in low battery condition.
NOTE: If you plan to be away from the premises over 30
days, we recommend that you replace the old batteries
with new alkaline batteries prior to leaving.

INSTALLATION

What You Need (Note: A fossil fuel kit is required.):
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.
• Slotted screwdriver(s) • Small Philips screwdriver •
Hammer • Electric drill, 3/16" bit • Two 1.5V (AA) size alkaline
batteries (included)

2. Remove Old Thermostat: A standard heat/cool
No
thermostat consists of three basic parts:
a. The cover, which may be either a snap-on or hinge
type.
b. The base, which is removed by loosening all screws.
c. The switching subbase, which is removed by
unscrewing the mounting screws that hold it on the
wall or adaptor plate.
3. Remove the front cover of the old thermostat. With wires
still attached, remove wall plate from the wall. If the old
thermostat has a wall mounting plate, remove the ther-
mostat and the wall mounting plate as an assembly.
4. Identify each wire attached to the old thermostat.
5. Disconnect the wires from the old thermostat one at a
time.
DO NOT LET WIRES FALL BACK INTO THE WALL.
6. Install new thermostat using the following procedures.
WARNING
Do not use on circuits exceeding specified voltage.
Higher voltage will damage the control and could cause
a shock or fire hazard. Do not short out terminals on
gas valve or primary control to test. Incorrect wiring will
damage thermostat and could cause personal injury
and/or property damage.
Selector Switches
Figure 1. Electric/Gas Switch (Fan Option)
This thermostat is configured from the factory to operate a
heat/ cool, fossil fuel (gas, oil, etc.), forced air system. It is
configured correctly for any system that DOES NOT require
the thermostat to energize the fan on a call for heat. If your
system is an electric heat or heat-pump system that
requires the thermostat to turn on the fan on a call for heat,
locate the ELEC/GAS switch on the back of the thermostat
(see Figure 1) and switch it to the ELEC position. This will
allow the thermostat to energize the fan immediately on
a call for heat. If you are unsure if the heating/cooling
system requires the thermostat to control the fan, contact a
qualified heating and air conditioning service person. When
the thermostat is configured for heat pump, the thermostat
will always power the circulator fan on a call for heat in the
HEAT mode. The ELEC/GAS switch must be set to match
the type of auxiliary heat your system uses for proper
operation in the EMERGENCY mode.
All wiring diagrams are for typical systems only. Refer to
equipment manufacturer's instructions for specific system
wiring information.
Attach Thermostat Base to Wall
1. Remove the packing material from the thermostat. Gently
pull the cover straight off the base. Forcing or prying will
cause damage to the unit.
2. Connect wires beneath terminal screws on base using
appropriate wiring schematic (see Figure 2 through 6).
3. Place base over hole in wall and mark mounting hole
locations on wall using base as a template.
4. Move base out of the way. Drill mounting holes.
5. Fasten base loosely to wall, as shown in Figure 1, using
two mounting screws. Place a level against bottom of
base, adjust until level, and then tighten screws. (Leveling
is for appearance only and will not affect thermostat
operation.) If you are using existing mounting holes, or if
holes drilled are too large and do not allow you to tighten
base snugly, use plastic screw anchors to secure base.
6. Push excess wire into wall and plug hole with a fire
resistant material (such as fiberglass insulation) to
prevent drafts from affecting thermostat operation.
