Use the drill and 3/1. Then, with the hammer, tap the supplied anchors into the mounting holes. With the anchors in place on the wall, align the base of the thermostat with the anchors and place the control wires through the wire opening. Use the screws included with your package to mount the thermostat base to the anchors. Insert the stripped, labeled wires into their matching wire terminals. Do not allow exposed wires to touch other wires. Tighten the screws on the terminal block with a screwdriver, then seal the hole for the wires behind the thermostat with nonflammable insulation or putty.
Set the "Gas/Electric" switch to match your system: "Gas" for oil or gas systems, "Electric" for heat pumps or electric heat systems. Insert two AA batteries into the thermostat, then snap the thermostat cover into place over the mounted base. Reactivate the power by replacing the fuse or switching the appropriate circuit breaker back to the "On" position.
