Read This Before Installing Thermostat

IMPORTANT

1, 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

2, All installation is normally performed at your thermostat.

ARMCHAIR PROGRAMMING

3, You can program your thermostat before installation by inserting the batteries and following the instructions starting Feature selector switches .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 Cool

1 6:00 ˚ F(20 ˚ C) 78 ˚ F(26 ˚ C)

2 8:00 ˚ F(16 ˚ C) 85 ˚ F(29 ˚ C)

3 4:00 ˚ F(20 ˚ C) 78 ˚ F(26 ˚ C) pm ˚ F(16 ˚ C) 82 ˚ F(28 ˚ C)

OPERATION

4 ， 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.

This Thermostat will NOT control multi-stage heat pumps or 110/220Volt systems.

COMPRESSOR PROTECTION

5, 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.

Temperature Range

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

7, Whenever the main power is interrupted or fails, the battery power retains and current time.

AUTO RECOVERY

8, 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 the Selector Switches information on Selector switches

BATTERY WARNING

9,Fresh alkaline batteries should provide over 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. y Slotted Screwdriver(s) y Small Philips screwdriver y Hammer y Electric drill and 3/16” bit y Two1.5V (AA) size alkaline batteries (included)

Remove Old Thermostat

CAUTION: Do not remove any wiring from existing thermostat before reading the instructions carefully. Wires must be labeled prior to removal.

INPORTANT! Turn off the power to the furnace at the main power panel or at the furnace.

Remove existing thermostat cover and thermostat. See Figure 1. Some thermostats will have screws or other locking devices that must first be removed. Once the 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.

Wiring Labeling

Figure

1 y 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 latter as shown in Table A below. y Note that this thermostat has multiple function terminals that allow Single-Stage Heat

Pump capability. Standard systems use: Rh, Rc, G, Y, W. [Single-Stage Heat Pumps use:

R, Y, G, and O or B.] Table A below shows the multiple functions of the terminals. Use the terminals that match your system. y 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. y There is often no terminal marking on the existing thermostat of two wire, heat only systems. Just connect either of the wires to the RH terminal, then connect the other wire to the W terminal to complete the circuit. y IMPORTANT! BEFORE DISCONNECTING ANY WIRES, APPLY THE

SELFADHESIVE LABELS PROVIDED TO THE WIRE AS SHOWN IN TABLE A

BELOW. (For example, attach the label marked W to the wire that toes 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. y After labeling wires, disconnect them from the existing thermostat. y Remove existing wallplate.

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. y Insert the tabs on top of the thermostat body into the slots at the top of the wallplate.

Press the bottom of the thermostat body into the snap on the bottom of the wallplate, as the terminal pins may be damaged. If it does not snap properly, the thermostat may not work.) y Insert the two AA size alkaline batteries, observing the polarity marked inside the battery compartment. y Switch on the main power at the panel or furnace.

Selector Switches

In order for this thermostat to control your system, the system type must be specified by the selector switches on the printed circuit board inside the thermostat. There is also a selector switch for your choice of Fahrenheit or Celsius temperature display. y Heating System Selector (HG – HE switch)

The factory position for this switch is in the “HG” position. Leave 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 after installation. If the Fan operation is normal, leave it in the “HG” position. If the Fan does not come on within minute of the thermostat calling for heating, 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. y Furnace or Heat Pump selector (NORMAL-O-B switch)

T he factory position for this switch is in the

NORMAL position. Leave it in this position if you have ANY system that uses gas, oil, electric, or hot water heating.

When any key is pressed the display is illuminated.

The display will remain illuminated for 8 seconds after the last key is pressed. This allows the light to stay on if you need to operate several keys.

Note: If the thermostat is in Low Battery warning condition, the backlight will not operate.

Replace with 2 new AA alkaline batteries to restore the Backlight function.

Low Battery Warning

Your thermostat has a two-stage lower 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.

When the batteries become too week 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 Set Temperature and Filter run time in memory until new batteries are installed. After confirming that new batteries have been inserted, the thermostat will return to normal operation.

Error Mode

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 “E1”or “E2”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.

Move the battery out hold any key then place the battery again. You will need to reprogram your thermostat and confirm normal operation.

If Error Mode returns, please call us for further information.

Auto Cut Off

Your thermostat will automatically cutoff in Heat mode if the room temperature rises above 95 ˚ F (35 ˚ C). It will cutoff in Cool mode if the room temperature drops below

40 ˚ F (4 ˚ C).

Note that if your system has malfunctioned and no longer responds to thermostat

controls, the Auto Cut-Off will have no effect.
