LEGEND	Potentiometer Defaults Settings:
DCV— Demand Controlled Ventilation	Power Exhaust	Middle
	Minimum Pos.	Fully Closed
IAQ — Indoor Air Quality
	DCV Max.	Middle
LA — Low Ambient Lockout Device
	DCV Set	Middle
OAT — Outdoor-Air Temperature
	Enthalpy	C Setting
POT — Potentiometer

RAT — Return-Air Temperature

NOTES:

1.620 ohm, 1 watt 5% resistor should be removed only when using differential enthalpy or dry bulb.

2.If a separate field-supplied 24 v transformer is used for the IAQ sensor power supply, it cannot have the secondary of the transformer grounded.

3.For field-installed remote minimum position POT, remove black wire jumper between P and P1 and set control minimum position POT to the minimum position.
