Units Description
Warm−up time delay. The time that the supplemental heat is held off
Counts
during the first demand of warm−up. This parameter is only used if the
D:Sec.
parameter 1.17 is set to option 1.
Counts Blower on delay. The time before the blower turns on after a heating
B:Secs demand.
Counts Blower off delay. The time the blower stays on after the heating de-
B:Secs mand is lost
Service output activation. Maximum Primary and Secondary Limit
occurrences stored before service relay is energized. If max value
Counts
is set, service output is disabled.
Note: Heating stage is not locked out.
Counts
Time delay between 1 & 2 stage of supplemental heat.
B:Secs
Temperature setpoint for lockout for the second bank of supplemental
Counts
heat.
Note: Temperature must be < or = to ECTO 1.07.
Counts Temperature setpoint for lockout of first bank of supplemental heat.
Y: Deg. Note: Temperature must be = to or > ECTO1.06.
Low ambient lockout for compressor 1. 254 value equals −30 ºF (−34ºC).
Counts
A value of 255 (−31ºF) will disable low ambient lockout function.
Y: Deg.
Note: This lockout is for heating only. Temperature must be < or = 1.09.
Low ambient lockout for compressor 2. 254 value equals −30 ºF (−34ºC).
Counts
A value of 255 (−31ºF) will disable low ambient lockout function.
Y: Deg.
Note: This lockout is for heating only. Temperature must be > or = 1.08.
Counts Compressor minimum off delay. Used on 1 PH units. Also used on all
A:Sec units after an alarm occurs.
Counts
Compressor minimum run time. Used on 3 PH units.

Maximum defrost time allowed.
Min
Warm−up mode option.
0− Supplemental heat may be used during warm−up. Use depends
on outdoor temperature. See ECTO 1.06 and 1.07.
Option 1− For the first demand cycle, lockout supplemental heat for the
first 30 minutes (default). Time is adjustable by changing the
parameter WARM−UP DLY # 1.01.
2− For future use.
Supplemental heat stage 1 differential. Used in zone sensor applica-

tions.
Note: Differential temperature must be = to or > ECTO 1.18
