17. Electronic Configure To Order (ECTO) Control Parameters
Units Description
Counts Time delay before a lower stage turns off following a higher stage
F: Sec termination. Used in zone sensor applications.
Modulating Gas Valve Mode
0− A133 (GP1) not installed.
1− A133 (GP1 w/DIP set to MGV) installed, but no MGV. Data log-
ging only.
2− Two−stage fire; min. or 100% (with or without low−fire FAH)
3− 2 + modulating FAH
4− Direct mode.
Option
AI1 (A133_P194−11) scaled to 0−100% and output on AO1.
AI2 (A133_P194_12)scaled to 0−100% and output on AO2.
5− DACH control; min. to maximum (with or without lo−fire FAH)
6− 5 + modulating FAH
Lighting sequence is followed for all modes; 2−6. See ECTO 3.14 and
3.15.
Modulating gas startup delay. At startup, run burners on low stage
main gas valves(s) with MGV(s) at 100% for ECTO 3.05 seconds.
Counts
Increase burners to high stage of main gas valve(s) with MGV(s)
A: Sec.
opened to ECTO 3.15 for ECTO 3.14 seconds. Begin PID or staged
control of MGV(s).
Counts
Modulating gas valve maximum.
P:%
Counts
Modulating gas valve minimum.
P:%
Counts
Modulating gas valve PID manual reset value.
P:%
Counts Modulating gas valve PID proportional constant.
Counts Modulating gas valve PID integral constant.
Counts Modulating gas valve PID derivative constant.
