MOUNTING AND WIRING

WARNING: Hazard of Electrical Shock. Disconnect all power before wiring or servicing this control.

1.Electric wiring to heater must be installed in accordance with Local and National Electrical Codes.

WARNING: Use copper conductors only.

2.Pull thermostat wires through large opening in center of wall mounting plate and fasten wires beneath proper terminal screws as follows:

A. Connect to 4 and 5 as shown.

3.Push excess wire into wall or switch box and plug up hole to prevent drafts from affecting thermostat operations.

4.Thermostat must be level to assure optimum performance. Place level on top of wall mounting plate and mark hole loca- tions for mounting screws. Attach plate loosely to wall with the two screws provided. Again, place level on top of plate to be sure it is level. Then, tighten mounting screws.

5.Remove cover from thermostat by pulling outward. Remove and discard pad (shipping protection for switch). Place ther- mostat base onto wall mounting plate and securely tighten all three screws (four for heating-cooling models). Then, snap on thermostat cover.
