Description
GP1 Digital Out Mode = X + 32*Y + 16*Z
Input source= X:
0− None.
1− Compressor 1 duty cycle. (Compressor crankcase heater func-
tion.) On when OAT <= ECTO 3.22 and >= ECTO 3.23 seconds
have passed with compressor 1 off. Off when OAT > ECTO3.22
+ 3ºF (fixed deadband) or < ECTO 3.23 sec have passed with
compressor 1 off
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 (A55_P298_5 RH)
8− System IAQ. (A55_P298_3 IAQ)
9− System OAT (A55_P267_1/2 OAT)
7− System RH (Either A55_ P114−10 or network RH)
11− AI2 (A133_P194−7) (SP and DB set with ECTO3.22 & 3.23)
12− AI3 (A133_P194−8) (SP and DB set with ECTO3.22 & 3.23)
13− AI4 (A133_P194−9) (SP and DB set with ECTO3.22 & 3.23)
14− AO1 (A133_P194−11)
15− AO2 (A133_P194−12)
Algorithm Y for input sources 7−15:
0− Hysteresis loop
On when input >= ECTO 3.22
Off when input < ECTO 3.22−ECTO 3.23
1 Window
On when input is in range; >= ECTO 3.22
and <= ECTO 3.22 + ECTO 3.23
(Fixed 3−count hysteresis loop on rising and
falling edges of window.)
2− Delayed−on.
On when input is >= ECTO 3.22
for >= ECTO 3.23 seconds.
Off when input is < ECTO 3.22 − 3.
(Fixed 3−count hysteresis loop on edge.)
3− Delayed−off.
On when input is >= ECTO 3.22.
Off when input is < ECTO 3.22 −3
for >= ECTO 3.23 seconds.
(Fixed 3−count hysteresis loop on edge.)
Inversion Z:
0 − Output not inverted.
1 − Output inverted.
