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.

●Do not locate in a damp area. This can lead to corro- sion that will shorten thermostat life.

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

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

●Do not install it where there are unusual heating condi- tions, such as: in direct sunlight; near a lamp, radio, tele- vision, radiator, register, or fireplace; near hot water pipes in a wall; near a stove on the other side of a wall.

●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.

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

3.3. REMOVAL OF OLD UNIT

CAUTION: 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 they may not comply with any standard.

●Switch electricity to the furnace and air conditioner OFF; then proceed with the following steps.

●Remove cover from old thermostat. Most are snap-on types and simply pull off. Some have locking screws on the on the side. These must be loosened.

●Note the letters printed near the terminals. Attach labels (enclosed) to each wire for identification. Label and remove wires one at a time. Make sure the wires do not fall back inside the wall.

●Loosen all screws on the old thermostat and remove it from the wall.

3.4. MOUNTING

CAUTION: Be careful not to drop the unit or disturb electronic parts.

●Strip insulation 3/8 in. (9.5mm) from wire ends and clean off any corrosion.

●Fill wall opening with non-combustible insulation to prevent drafts from affecting the thermostat.

●With each thumb on a release tab at the bottom of the body, and fingers over the top of the unit. Release the unit from its base plate by squeezing the tabs into the body.

●Separate the unit from its base plate by pulling the body outward from the bottom.

NOTE: If you are mounting the base to a soft material like plasterboard or if you are using the old mounting holes, the screws may not hold. Drill a 3/16-in. (4.8mm) hole at each screw location, and insert the plastic anchors provided. Then mount the base as described below.

●Route the wires through the open areas in the base plate above the terminals. Hold the base against the wall, with the wires coming through. Position the base for the best appearance (to hide any marks from an old thermo- stat). Attach the base to the wall with the two screws pro- vided.

1.G The fan terminal is live at any time the thermostat attempts to turn the system fan or blower on.

2.O This terminal is live at any time the unit is in Cool mode.

3.Y2 Activation of this terminal signifies that the thermostat is calling for a second stage of cooling. This terminal will remain inactive unless a second stage compressor has been specified in the installer setup menu.

4.Y1 Activation of this terminal signifies that the thermostat is calling for a first compressor stage. This terminal will remain inactive unless at least one compressor stage has been specified in the installer setup menu.

5.RC This terminal provides power to the cooling and fan terminals.

6.C Use of this terminal allows the unit to be

system powered rather than battery powered. Note that the display backlight is battery powered only.

7RH This terminal provides power to the heating terminals.

8.W1 This terminal is active when the thermostat is calling for the first available stage of furnace or electric heat. It will remain inactive unless at least one stage of furnace type heat has been specified in the installer setup menu.
