AIN4	1.9 volts (100°F) - 3.6 volts (40°F)
Outdoor Air Temp	Typical is 2.5 volts @ 77°F
AIN5	If the input is OPEN, the voltage will be greater than 5.0 volts
Manual Reset	If the input is CLOSED, the voltage will be less than 0.5 volts
AIN7	If the input is OPEN, the voltage will be greater than 5.0 volts
Phase Loss	If the input is CLOSED, the voltage will be less than 0.5 volts
AIN1-Exp. Bd.	If the input is OPEN, the voltage will be greater than 5.0 volts
Fire Alarm	If the input is CLOSED, the voltage will be less than 0.5 volts
	Caution: AIN1 – Fire/Smoke input must be connected
	to the AIN1- GND terminal. If it is not used, a jumper must be
	installed, since this is a normally closed contact input. If this
	is not done the system will not operate.
AIN2-Exp. Bd.	If the input is OPEN, the voltage will be greater than 5.0 volts
Request to Run	If the input is CLOSED, the voltage will be less than 0.5 volts
