INSTALLATION 10-11 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) ■ Phillips Screwdriver ■ Hammer ■ Electric drill and 3/16" bit ■ Two 1.5 V (AA) size alkaline batteries Remove Old Thermostat CAUTION: Do not remove any wiring from existing thermostat before reading the instructions carefully. WIRES MUST BE LABELED PRIOR TO REMOVAL.
Wire Labeling ■ Each wire coming from the wall to the existing thermostat is connected to a terminal point on that thermostat. Each of these terminal points is usually marked with a code letter as shown in Table A on this page. ■ The number of wires in your system can be as few as two (for heat only systems), as many as eight, or any number in between. If you follow the labeling procedures correctly, you do not have to be concerned about how many wires there are.
INSTALLATION 12-13 Mount Wallplate and Thermostat ■ Remove the wallplate from your thermostat by pressing the release tab on the bottom of the thermostat. (See Figure 2.) ■ Position wallplate on wall and pull existing wires through large opening. Then level for appearance. Mark holes for plastic anchors provided if your existing holes do not line up with those on the Hunter wallplate. ■ Drill holes with 3/16” bit and gently tap anchors into the holes until flush with wall.
B99A p1-19 2/7/03 9:58 AM Page 13 Connect Wires and Mount Thermostat Cover to Wall Plate ■ Match and connect the labeled wires to the appropriate coded terminal screws on the mounting plate. (See Figure 4, 5.) Ignore any wires which may be present, but which were not connected to the old thermostat. ■ Be sure to tighten the terminal screws securely, otherwise a loose wire could cause operational problems with your system or thermostat.
