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.

■Slotted Screwdriver(s) ■ Electric drill and 3/16" bit

■Phillips Screwdriver ■ Two 1.5 V (AA) size alkaline batteries

■Hammer

Remove Old Thermostat

CAUTION: Do not remove any wiring from existing thermostat before reading the instructions carefully. WIRES MUST BE LABELED PRIOR TO REMOVAL.

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

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

Figure 2

■Drill holes with 3/16" bit and gently tap anchors into the holes until flush with wall.

■Reposition wallplate to wall, pulling wires through large opening. Insert mounting screws provided into wall anchor and tighten. (See Figure 3.)

Connect Wires and Mount Thermostat to Wallplate

15

■Straighten bare end of each wire and cut or strip it to 1/4” maximum. Insert each labeled wire into the bottom of the maching terminal. Refer to figures 4 and 5.

■Hold the wires in each terminal and tighten the terminal screws securely, otherwise a loose wire could cause operational problems with your system or thermostat.

■Push excess wire back into hole to prevent interference with mounting of the thermostat.

■Make sure the Power Switch is set to OFF.

■Insert two AAA size alkaline batteries, observing the polarity marked on the unit.

■Insert the upper tabs on the thermostat body into the slot at the top of the wallplate. Press bottom of the thermostat body to snap it into the wallplate. (NOTE: Do not force the thermostat onto the wallplate, as the terminal pins may be damaged. If it does not snap properly, the thermostat may not work.)

■Switch on the main power at the panel or furnace.
