[. . . ] T8095A/191108AJ/Q682B Heating, Cooling and Heating/Cooling Thermostat, Wallplate, and Subbase; TS8095A/191108AC Heating-Only Thermostat and Wallplate Installation Instructions for the Trained Service Technician. Preparation Check thermostat and subbase (if used) suitability for the heating, cooling, or heating/cooling system. Assemble tools required: flat bladed screwdriver, hand or power drill with 3/16-in. drill bit, wire cutter/stripper or sharp knife, bubble level or plumb bob and line. Assure power is off to the heating, cooling, or heating/ cooling system at the main fuse panel. [. . . ] NOTE: If wiring a dual transformer system, only the O or the B terminal may be used. Plug the hole in wall with nonhardening caulk, putty, or nonflammable insulation to prevent drafts from affecting thermostat operation. Fig. 5--Methods of connecting terminals. FOR STRAIGHT CONNECTION-- STRIP 5/16 in. [8 mm] Hang the thermostat base on the wallplate or subbase. Insert the two captive mounting screws located in the bottom corners of the base (Fig. INSERT CLOCK BATTERIES Power is supplied to the clock by the 24-Vac transformer. Backup batteries (not included) may be installed to supply power to the clock if power is interrupted. Install the batteries in the thermostat (Fig. Once a year or when batteries are dead, replace with two new AAA alkaline batteries. We recommend Energizer® batteries. Fig. 6--Thermostat mounting.

PROGRAM DIAL MINUTE HAND TIME INDICATOR ARROW SET HEAT ANTICIPATOR Adjust the heat anticipator lever to match the current rating of the primary control for the proper cycle rate (Fig. Adjustable anticipation must be set for total current of heat and fan control. [. . . ] If the thermometer reading and the high temperature lever position are approximately the same at the instant the mercury moves to the other end, no recalibration is needed. If calibration is necessary, proceed as follows: 1. Place open-end calibration wrench, part no. 104994A (ordered separately), on the hex nut under the bimetallic coil controlled by the red lever (Fig. [. . . ]
