Please read this manual for complete instructions on installing and operating your thermostat. If you require further assistance, please feel free to contact us

IMPORTANT INFORMATION

1. This thermostat is designed to work on the following systems:

y Gas – Standing Pilot y Oil – Fired Furnace y Gas – Electronic Ignition y Single Stage Heat Pumps –

y Gas – Fired Boilers y Electric Air Conditioning y Gas – Millivolt Systems y Electric Furnace y Oil – Fired Boilers

This thermostat will NOT control multistage heat pumps or 110/220V baseboard electric heating systems.

2. 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 displaye d 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).

3. Compressor Protection

This thermostat provides a 4 minutes delay after shutting off the cooling system before it can be restarted. This feature will prevent damage to your compressor caused b y rapid cycling. It does not prevent a rapid compressor restart due to short power outages.

4. Battery Warning

Two fresh AA alkaline batteries should provide well over one year of service. However, when the batteries become drained, the Low Battery Indicator will flas h on the display. When this message occurs, install new alkaline batteries. You have approximately 1 minute to change the batteries and keep the thermos tat’s clock and program settings. Once the batteries have become too low to ensure prope r operation, your system will be turned off, and the display will be cleared except for flashing Lo w Battery Indicator on the LCD display.

CAUTION: When only the Low Battery icon flashes on the display, 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.

SPAN Setting

Your thermostat is set at the factory to cycle at 2˚F (1˚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. y Press and hold BOTH (up and down keys) for three seconds.

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 re

store the Backlight function.

In this condition, “BATT” flashes alone on the display, and the thermostat will turn your system off. remain shut-off until the batteries are replaced.

Note: The thermostat will still keep the c urrent Set Temperature an memory until new batteries are installed. After confirming that new batte inserted, the thermostat will return to normal operation.

Auto Recovery

Auto Recovery calculates how early to turn you s ystem back on, so that the room temperature is already comfortable by the start of the comfort temperature program period. Auto Recovery work’s in both Heat and Cool modes. yWhen the thermostat is in Auto Recovery mode, the display will alternate “RECO” with time, and the program indicator will flash. yAuto Recovery can be disabled by sliding the Recover y switch on the circuit board to disable. yAuto Recovery will not operate if Permanent hold or Temporary hold is in operation. yAuto Recovery can be canceled manually if Hold/RETURN is pressed durin g the recovery process. yAuto Recovery will be canceled and change to next period.

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 hol 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 45˚F (7˚C).

Mechanical Heat Backup

This thermostat includes a bimetal switch that will automatically turn on the Heat when the tem

perature reaches about 41˚F (5˚C).

Selector Switches

In order for this thermostat to control your system, the s ystem type must be s pecified 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 F˚ / C˚ selector (Fahrenheit / Celsius) Your thermostat is set for F˚ mode from the factory. In order to ch slide the switch to C˚ and Move the battery out and wait for about 1 minute the n place the batteries ..

NOTE: Unless press any key about 2 seconds without the battery, then place the battery again. the thermostat will not change temperature mode. All programs an settings will be lost .

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 furna

ce 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 a minute of the thermostat calling for he

ating, 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 System Selector (STANDARD – HEAT PUMP 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. Be sure the reversing valve wire is connected to the correct terminal for your heat pump (Y/O) or (W/B).

y 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 DISABLE position.

NOTE: 5- Wire Systems

If your thermostat has one wire marked R or Rh (2, 3, or 4-wire system), then leave the jumper wire between the Rh and Rc terminals on the wall plate. Otherwise, if you have separate Rh and Rc wires (5-wire system), then remo ve the jumper wire bet ween the Rh and Rc terminals.

Connect Wires and Mo

y 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 note connected to the old thermostat.

y Refer to the Wiring Diagrams below to be sure your system is wired correctly. y If your system is a single stage heat pump and uses an O or B wire, you m ust 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. y Be sure to tighten the terminal screw operational problems with your system or thermostat. y Push excess wires back into the hole to prevent interfere nce when installing the thermostat to the wallplate.

y Make sure the System Switch is set to OFF, and the Fan Switch is set to AUTO. y Insert the bottom tabs on the thermostat body into the slo ts at the bottom of the
