Night Setback: This defines the
start and end times when the
setback parameters are active.
These times must be given in
24-hour format (e.g., 6:00 p.m. is
written as 18:00.)
Warmup Setup: This defines how warmup is
performed to ready the space for daytime
temperatures. If the temperature outside is below
either temperature in the T outside boxes, warmup
will take place. Warmup will begin at the number of
minutes before the end of night setback given in the
Delay box. See example below.
Cooling Setpoints: This
area defines when cooling is
activated during night
setback.

Auxiliary Setpoints: This defines

Dehum. Setpoints: This defines when
dehumidification is used during night
setback.
Available during night set back: Placing a check in the
box will make the dehumidification and auxiliary heat
outputs available during night setback. Removing the
check will prevent dehumidification or auxiliary heat
during night setback times.
