IMPORTANT
1. Read the entire installation section of this Owner's Manual thoroughly before you
begin to install or operate your Thermostat.
This thermostat can be used for conventional or heat pump systems.
Please configure the thermostat according to Configuration Menu
before operation.
REMOVE THE MYLAR LABEL FROM THE LCD DISPLAY WINDOW.
INSTALLATION
2. All installation is normally performed at your thermostat.
ARMCHAIR PROGRAMMING
3. You can program your thermostat before installation by inserting the batteries and
ollowing the instructions starting at the configuration menu. 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 thermostat.
The following time and temperature settings are pre-programmed into the thermostat:
Temperature in ˚F (˚C)
Program Number Time Heat
1 6:00 am 68˚F(20˚C)
2 8:00 am 60˚F(16˚C)
3 4:00 pm 68˚F(20˚C)
4 10:00 pm 60˚F(16˚C)
COMPRESSOR PROTECTION
4. The thermostat provides a 4 minute delay after shutting of 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 at the configuration.
TEMPERATURE RANGE
5. This thermostat can be programmed between 45˚F and 95˚F (7˚C and 35˚C).
However, it will display room temperatures from 30˚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 30˚F (0˚C). This thermostat will automatically shut off in Heat
mode if the temperature rises above 72˚F (22˚C), and automatically shut off in Cool
mode if the temperature drops below 75˚F (24˚C).
NOTE: if the thermostat measures a temperature over 99˚F(37℃), "HI" will be displayed
on the LCD. if the temperature is below 32˚F(0℃) and "LO" will be displayed on the LCD.
POWER FAILURE
6. Whenever the main power is interrupted or fails, the battery power retains the
current time. This thermostat has permanent memory, although you will have to reset
your clock when there are power outages.
POWER SUPPLY
7. The thermostat shall be powered by 24 VAC and with batteries as backup.
BATTERY WARNING
8. Fresh alkaline batteries should provide about one year of service. However, when the
batteries become drained, "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 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 "BATT" flashing on the LCD display.
CAUTION: Once only the "BATT" 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 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
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
■ Electric drill and 3/16" bit ■ Two 1.5V (AA) size alkaline batteries (included)
CAUTION:
To prevent electrical shock and/or equipment damage, disconnect electric power
to system at main fuse or circuit breaker box until installation is complete.
Before removing wires from old thermostat's switching subbase, label each wire with the
terminal designation it was removed from.
1. Shut off electricity at the main fuse box until installation is complete. Ensure that
electrical power is disconnected.
2. Remove Old Thermostat: A standard heat/cool 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 captive 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
thermostat 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
control and could cause shock or fire hazard. Do not short out terminals on gas
valve or primary control to test. Shorts or incorrect wiring will damage the
thermostat and could cause personal injury and/or property damage.

Auto Programming
Studies conducted by the Department of Energy estimate that
setting your thermostat back 10˚F (6℃) for two 8-hour periods
during winter can reduce your fuel bill by as much as 33%. By
setting your thermostat up 5˚F (3℃) for two 8-hour periods during
summer you can reduce your fuel bill up to 25%.
Your thermostat is capable of holding up to 4 separate programs
for each day of the week. You can program all weekdays, Monday
to Friday, to the same 4 programs as shown in the table, or each
weekday can have a different set of 4 programs. Similarly
weekend programs, Saturday and Sunday, can be the same 4
programs or each weekend day can have a different set of 4 programs.
Your thermostat is pre-programmed to meet the ENERGY STAR guidelines for energy
efficiency. Note that it is easier to modify these programs than it is
to program the thermostat manually.
■ Press once. During Auto Programming, the
