17. Electronic Configure To Order (ECTO) Control Parameters
Description
GP1 Digital Out Control 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 9.24 and >= ECTO 9.25 seconds
have passed with compressor 1 off. Off when OAT > ECTO 9.24
+ 3 deg F (fixed deadband) or < ECTO 9.25 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− On base on AI1. (A133_P194−6)
11− On based on AI2. (A133_P194−7)
12− On based on AI3. (A133_P194−8)
13− On based on AI4. (A133_P194−9)
14− On based on AO1. (A133_P194−11)
15− On based on AO2. (A133_P194−12)
Algorithm Y for input sources 7−15:
0− Hysteresis loop
On when input >= ECTO 9.24
Off when input < ECTO 9.24−ECTO 9.25
1− Window
On when input is in range; >= ECTO 9.24
and <= ECTO 9.24 + ECTO 9.25
(Fixed 3−count hysteresis loop on rising
and falling edges of window.)
2− Delayed−on.
On when input is >= ECTO 9.24
for >= ECTO 9.25 seconds.
Off when input is < ECTO 9.24 − 3.
(Fixed 3−count hysteresis loop on edge.)
3− Delayed−off.
On when input is >= ECTO 9.24.
Off when input is < ECTO 9.24 − 3
for >= ECTO 9.25 seconds.
(Fixed 3−count hysteresis loop on edge.)
Inversion Z:
0 − Output not inverted.
1 − Output inverted.
