ATTACH THERMOSTAT TO SUBBASE

1.Remove cover from thermostat base 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.Attach thermostat base to subbase, being sure that all captive screws are tightened snugly, since they serve as electrical connections between thermostat and subbase (see fig. 4).

4.Snap cover on thermostat and set switches and tem- perature lever to desired setpoint (see OPERATION section).

5.Turn on power to the system.

This thermostat is easy to operate. Fig. 5 shows how the heating/cooling system and fan operate when the switches are in various positions. Use the system switch to select either heating or cooling, or to turn the heating/cooling system off. Use the fan switch to control fan operation. When the fan switch is in the AUTO position, the fan will cycle with the heating or cooling system (the fan will not run if the system switch is in the OFF position and the fan switch is in the AUTO posi- tion). When the fan switch is in the ON position, the fan will run continuously, regardless of system switch position (even if the system switch is set to OFF, the fan will run if the fan switch is in the ON position).
