General Purpose D01 Digital output
control mode set point.
EXAMPLE: If this Parameter is set
% to 10%, then the dead-
band in Fahrenheit would
be (DO Temperature Set
Point * 10 /100).
For delay on or delay off.
GP3 Digital Out Control Mode = X + 32*Y
+ 16*Z
Input Sources X:
• 0 = None.
• 1 = Compressor 1 duty cycle.
(Compressor crankcase heater
function)

temperature is < = Parameter
369 and > = P 371 seconds

1 off.
> Off when outdoor air

+ 3°F (fixed dead-band) or
compressor 1 is turned on.
• 2 = On when Occupied
• 3 = On when blower on.
• 4 = On when heating demand
• 5 = On when cooling demand
• 6 = On when heating or cooling

demand
• 7 = System RH (use Parameter 368)
• 8 = System IAQ (use Parameter
367)
• 9 = System OAT (use Parameter
369)
• 10 = On based on GP3 Temperature
Sensor 1 (use Parameter 369)
• 11 = On based on GP3 Temperature
Sensor 2 (use Parameter 369)
• 12 = On based on GP3 AI1 (use
Parameter 366)
• 13 = On based on GP3 AI2 (use
Parameter 366)
• 14 = On based on GP3 AO1 (use
Parameter 366)
• 15 = On based on GP3 AO2 (use
Parameter 366)
