IMPORTANT

2, Read the entire installation section of this Owner’s Manual thoroughly

before you begin to install or operate your Thermostat.

REMOVE THE MYLAR LABEL FORM THE LCD DISPLAY WINDOW.

INSTALLATION

3, All installation is normally performed at your thermostat.

COMPRESSOR PROTECTION

4，The thermostat provides a 4 minutes 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 cutoff in Heat mode if the temperature rises

above 95˚F (35˚C), and automatically cutoff in Cool mode if the temperature

drops below 45˚F (7˚C).

NOTE: The thermostat will automatically change to the Cool mode if the

thermostat measure a temperature over 99˚F(37℃), ”HI” will be displayed on

the LCD, and the Cooling system will turn On. Similarly, the thermostat will

automatically change to the Heat mode if the temperature is below 32˚F(0℃).

and ”LO” will be displayed on the LCD, and the Heating system will turn On.

POWER FAILURE

6， Whenever the main power is interrupted or fails, the battery power

retains and 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. 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 ■ Hammer

■ Electric drill and 3/16” bit ■ Two1.5V (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. Short or incorrect

wiring will damage thermostat and could cause personal injury and/or

property damage.

Selector Switches

Electric/Gas Switch (Fan Option)

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 you 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 fig. 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

manufacturers’ 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 on the thermostat will cause damage

to the unit.

2. Connect wires beneath terminal screws on base using appropriate wiring

schematic (see figs. 2 through 4).

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 fig. 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 subbase.

6. Push excess wire into wall and plug hole with a fireresistant material (such

as fiberglass insulation) to prevent drafts from affecting thermostat operation.

Heat Pump Terminal Outputs

Refer to equipment manufacturers' instructions for specific system wiring

information. You can configure the thermostat for use with the following heat

pump system types: HEAT PUMP TYPE 1 1. Single stage compressor

system; gas or electric backup. This thermostat is designed to operate a

single-transformer system. If you have a two-transformer system, cut and

tape off one transformer. If transformer safety circuits are in only one of the

systems, remove the transformer of the system with NO safety circuits. If

required, replace remaining transformer with a 75VA Class II transformer.

After disconnecting one transformer, the two commons must be jumpered

together.

Use the terminal output information below to help you wire the thermostat

properly for your heat pump system. After wiring, see CONFIGURATION

section for proper thermostat configuration.
