A55 Service Output Control Mode = X + 32*Y + 16*Z
Input source = X:
0− None. Standard Service Output based on alarms.
1− Compressor 1 duty cycle. (Compressor crankcase heater func-
tion.)
On when OAT < = ECTO 7.23 and >= ECTO 7.24 seconds have
passed with compressor 1 off. Off when OAT > ECTO 7.23 + 3
deg F (fixed deadband) or < ECTO 7.24 seconds 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− Energy Recovery System (ERS) option.
11− SCR option for electric heat. DO−1 on with blower but off with
cooling.
Algorithm Y for input sources 7−9:
0− Hysteresis loop
On when input >= ECTO 7.23
Off when input < ECTO 7.23−ECTO 7.24
1− Window
On when input is in range; >= ECTO
7.25
and <= ECTO 7.23 + ECTO 7.24
(Fixed 3−count hysteresis loop on rising
and falling edges of window.)
2− Delayed−on
On when input is >= ECTO 7.23
for >= ECTO 7.24 seconds.
Off when input is < ECTO 7.23−3.
(Fixed 3−count hysteresis loop on edge.)
3− Delayed−off
On when input is >= ECTO 7.23.
Off when input is < ECTO7.23 − 3
for >= ECTO 7.24 seconds.
(Fixed 3−count hysteresis loop on edge.)
Inversion Z:
0 − Output not inverted.
1 − Output inverted.
