should touch another metal object before the unit to avoid potential loss of programs.

SETTING THE TIME OF DAY

Open the drop down door on the front of the thermostat. Rotate the dial to the SET DAY/TIME position. You should see the display pictured above with a day of the week flashing. When you are finished setting the day and time, rotate the dial to RUN to return to normal operation or to another position to continue programming.

C A U T I O N

•Your thermostat is a precision instrument. Please handle it with care.

•Turn off electricity to the appliance before installing or servicing thermostat or any part of the system. Do not turn electricity back on until work is completed.

•Do not short (jumper) across electric terminals at control on furnace or air conditioner to test the system. This will damage the thermostat and void your warranty.

•All wiring must conform to local codes and ordinances.

•This thermostat is designed for use with 24 volt and millivolt systems. The thermostat should be limited to a maximum of 1.0 amps; higher amperage may cause damage to the thermostat. If you are in doubt, call your utility company.

On replacement installations, mount the

new thermostat in place of the old one unless the conditions listed below suggest otherwise. On new installations, follow the guidelines listed below.

1.Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the floor, and in a room that is used often.

2.Do not install it where there are unusual heating conditions, such as: in direct

sunlight; near a lamp, radio, television, radiator, register, or fireplace; near hot water pipes in a wall; near a stove on the other side of a wall.

3.Do not locate in unusual cooling conditions, such as: on a wall separating an unheated room; or in a draft from a stairwell, door, or window.

4.Do not locate in a damp area. This can lead to corrosion that will shorten thermostat life.

5.Do not locate where air circulation is poor, such as: in a corner or an alcove; or behind an open door.

6.Do not install the unit until all construction work and painting has been completed.

7.This thermostat does not require leveling.

Installation is now complete. Be sure to turn the power

back on to your heating and /or air conditioning system. If this is the first time you are installing batteries, the thermostat will display “SUN 12:00 AM”. Within 90 seconds the thermostat will begin to display the room temperature alternately with the time. To correct the display, see “Setting the TIME and DAY,” after you set the programs.

OPERATION

The Unit alternately displays the current time and the room temperature. It also displays the day of the week and the currently active pro-

gram period that is controlling the temperature: MORN, DAY, EVE, or NIght.

The set point temperature will appear in the right side of the display. In the winter, set the system switch to HEAT to control your heating system. In the summer, set the switch to COOL to control your air conditioner. In spring and fall or when windows are open, you can set the system switch OFF.

TEMPERATURE SWING

A thermostat works by turning your heating or cooling system on and off whenever the room temperature varies a certain number of degrees from the set-point temperature. This variation is the “swing.” Your system should cycle on about 3 to 6 times per hour. A smaller swing number increases the number of cycles, so room temperature is more constant. A larger swing number decreases the number of cycles, to save energy in most cases.

•Press the reset key on the front of the thermostat for changes to take effect.

•Reprogram as necessary.

SMART RECOVERY

Your thermostat has the capability to turn the HEAT and AIR CONDITIONING ON in your home so that it reaches your desired comfort temperature at the time you have programmed. For instance, if you have pro- grammed your thermostat for 70° at 5:00pm, normally the thermostat will begin to heat your home at 5:00pm. With SMART RECOVERY on, the thermostat will calculate the best time to turn the heat on so that the temper- ature in your home reaches 70° by 5:00pm. It calculates the amount of time through experience and will get more accurate as time goes by. To enable SMART RECOVERY, remove J4 on the back of the thermostat. Press the small reset button on the front of the thermostat. IN RECOVERY will appear in the display when this feature is bringing your home to temperature.
