0 0 127 Option
A133 (w/DIP set to VAV) Digital Out Mode = X + 32*Y + 16*Z
Input source= X:
0− None. Output enables exhaust fan stage 2.
1− Compressor 1 duty cycle. (Compressor crankcase heater func-
tion.) On when OAT <= ECTO 0.24 and >= ECTO 0.25 seconds
have passed with compressor 1 off. Off when OAT > ECTO 0.24
+ 3 deg F (fixed deadband) or < ECTO 0.25 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)
10− AI1. (A133_P194−6).
11− AI2. (A133_P194−7).
12− AI3. (A133_P194−8).
13− AI4. (A133_P194−9).
14− AO1. (A133_P194−11).
15 AO2. (A133_P194−12).
Algorithm Y for input sources 7−15:
0− Hysteresis loop
On when input >= ECTO 0.24
Off when input < ECTO 0.24−ECTO 0.25
1− Window
On when input is in range; >= ECTO 0.24
and <= ECTO 0.24 + ECTO 0.25
(Fixed 3−count hysteresis loop on rising
and falling edges of window.)
2− Delayed−on.
On when input is >= ECTO 0.24
for >= ECTO 0.25 seconds.
Off when input is < ECTO 0.24 − 3.
(Fixed 3−count hysteresis loop on edge.)
3− Delayed−off.
On when input is >= ECTO 0.24.
Off when input is < ECTO 0.24 − 3
for >= ECTO 0.25 seconds.
(Fixed 3−count hysteresis loop on edge.)
Inversion Z:
0 − Output not inverted.
1 − Output inverted.
