ATTACHING THERMOSTAT
1.Remove cover from thermostat by gripping the base in one hand. Use the other hand to pull gently at the top or bottom of the cover.
2.Carefully remove the shipping protective packing from the switch.
3.Pull wires through the opening in the thermostat base and connect wires beneath the terminal screws (see Fig. 2 & 3).
4.Push excess wiring back into wall and plug hole with fire resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation.
5.Position thermostat base over hole in wall and mark mounting hole location on wall.
6.Drill mounting hole.
7.Fasten base loosely to wall using mounting screws. Place a level against the top of the thermostat base, adjust until level, and tighten mounting screws to
secure base. If holes in wall are too large and do not allow you to tighten the mounting screws securely, use plastic expansion plugs.
8.Snap cover on the thermostat base and set tempera- ture lever to desired setpoint.
9.Turn on electrical power to system.
