17. Electronic Configure To Order (ECTO) Control Parameters
Units Description
Cool down tine delay. Time that Y2 is ignored during cool down period
Counts
(when first occupied + cool demand) This delay is only used if an
D:Sec.
economizer is used and the outdoor air is suitable.
Counts Blower on delay. The time before the blower turns on after a cooling
B:Sec. demand.
Counts Blower off delay. The time the blower stays on after the cooling de-
B:Sec. mand is lost.
Service output activation and compressor lockout. Maximum Freeze
Stat occurrences stored before service relay is energized and com-
Counts pressor is locked−out. If value (4 or 5) is set, service output is dis-
abled and compressor is not locked−out. If value 5 is set, alarms are
not stored, but only displayed as they occur.
Counts Low ambient anti−windmilling condenser fan delay. The time period
A:Sec. that the last operating fan is turned off before starting the next fan.
Low ambient outdoor air limit temp. 1. Parameters 4.06 and 4.07 are
Counts
used to shed fans. See Operation section. Temperature setting must
Y:DegF
be < or = 4.07.
Low ambient outdoor air limit temp. 2. Parameters 4.06 and 4.07 are
Counts
used to shed fans. See Operation section. Temperature setting must
be > or = 4.06.
Low ambient lockout for compressor 1.
Counts
A value of 255 (−31°F) will disable low ambient lockout function.
Temperature setting must be < or = 4.09.
Low ambient lockout for compressor 2.
Counts
A value of 255 (−31F) will disable low ambient lockout function.
Temperature setting must be > or = 4.08 AND < or = 4.10.
Low ambient lockout for compressor 3.
Counts
A value of 255(−31F) will disable low ambient lockout function.
Temperature setting must be > or = 4.09 AND < or = 4.11.
Low ambient lockout for compressor 4.
Counts
A value of 255 (−31F) will disable low ambient lockout function.
Temperature setting must be > or = 4.10.
Counts
Compressor minimum off delay. Used on 1 PH units.
A:Sec.
Counts
Compressor minimum run time. Used on 3 PH units.
A:Sec.
Maximum High Pressure occurrences that are stored before control
locks off compressor stage and energizes the service output. If max
Counts
value is set, lockout and service output features are disabled.
Maximum Low Pressure occurrences that are stored before control
Counts locks off compressor stage and energizes the service relay. If max
value is set, lockout and service output features are disabled.
Counts
Condenser fan delay. Used only on 6 fan units.
A:Sec.
Stage 2 latch option. Used in zone sensor applications.
Option 0: Latch Disabled
1: Latch Enabled
Stage 3 latch option. Used in zone sensor applications.
0: Latch Disabled
Option
1: Latch Enabled
Stage 4 latch option. Used in zone sensor applications.
Option 0: Latch Disabled
1: Latch Enabled
Stage 2 stage up timer. The maximum time that cooling stage 1 runs
Counts
before calling cooling stage 2. Used in zone sensor applications.
F:Sec
Disabled if set to 0.
Stage 3 stage up timer. The maximum time that cooling stage 2 runs
Counts
before calling cooling stage 3. Used in zone sensor applications.
F:Sec
Disabled if set to 0.
Stage 4 stage up timer. The maximum time that cooling stage 3 runs
Counts
before calling cooling stage 4. Used in zone sensor applications.
F:Sec
Disabled if set to 0.
Counts Time delay before a lower stage turns off following a higher stage
F:Sec termination. Used in zone sensor applications.
