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.
TYPICAL SINGLE-STAGE HEAT PUMP HOOKUP
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.

REMOVING THE OLD THERMOSTAT
Switch electricity to the furnace and air conditioner OFF; then proceed with the following steps. 1. Remove cover from old thermostat. Most are snap-on types and simply pull off. Some have locking screws on the side. These must be loosened. 2. Note the letters printed near the terminals. Attach labels (enclosed) to each wire for identification. Remove and label wires one at a time. Make sure the wires do not fall back inside the wall. 3. Loosen all screws on the old thermostat and remove it from the wall.
Read instructions carefully before removing any wiring from existing thermostat. Wires must be labeled before they are removed. When removing wires from their terminals, ignore the color of the wires since these may not comply with the standard.

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.

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 programmed 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 temperature 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.
