Heating Mode: stage 1 calling. Fan relay,

compressor contactor, and reversing valve (B)

energized by thermostat.

Heating Mode: both stages calling. Fan relay,

compressor contactor, reversing valve (B),

and auxiliary heat relay are energized.

Emergency Heat Mode: aux heat, fan relay *,

and reversing valve (B) are energized.

Compressor locked out.

Cooling Mode: Fan relay, compressor

contactor and reversing valve (O) energized.

Fan On: Energizes fan relay regardless

of system switch position.

Indicates switch position on thermostat subbase and system function in operation.

* In Emergency Heat Mode, fan may be disabled, if required, by cutting jumper W7 (see fig 3).

This thermostat is easy to operate. The above table shows how the system will operate when the FAN and SYSTEM switches are in different positions.

To set the switches, open the door on the left side of the thermostat (see fig 6). Move the FAN and SYSTEM switches up or down to select desired system operation. To set the temperature, move the temperature selection knob (on the right side of the thermostat) until the desired temperature is shown in the window.

ANTICIPATION ADJUSTMENT

The anticipation setting on this thermostat is adjustable. Any anticipation setting (including the factory setting) will work with any system for which this thermostat is intended for use. However, the user may be more comfortable with a particular setting. If the system is turning on and off too often (short cycles) or not often enough (long cycles) for the user’s comfort, follow these steps to adjust the antici- pation.

First Stage Heat & Cool Second Stage & Emergency Heat

1.	Turn off power to the thermostat.
2.	Remove the thermostat cover.
3.	Find the anticipation adjustment switches (see fig. 3).
4.	Using a pencil or small screwdriver, move the switches
	to the desired setting (see figs. 7 and 8).
5.	Carefully snap the cover onto the thermostat base.
