Heating – (Occupied or Unoccupied, depending on mode) The current programmed
Heating setpoint adjusted by any offset that may be in effect.
R:
0 to 120°F
(-17.7 to 48.9°C)
Cooling – (Occupied or Unoccupied, depending on mode) The current programmed
Cooling setpoint adjusted by any offset that may be in effect.
R:
0 to 120°F
(-17.7 to 48.9°C)
Learned cooling capacity – The cooling capacity learned by Learning Adaptive Optimal
Start that is required to bring the space temperature down to the occupied cooling
setpoint prior to the occupied time.
R:
_°F/C
Learned heating capacity – The heating capacity learned by Learning Adaptive Optimal
Start that is required to bring the space temperature up to the occupied heating
setpoint prior to the occupied time.
R:
_°F/C
Optimal Start – The number of hours prior to occupancy, at which the Optimal Start
function may begin to adjust the effective setpoints to achieve the occupied setpoints
by the time scheduled occupancy begins. Enter 0 to disable Optimal Start.
NOTE Optimal Start is automatically disabled when Properties > Control Program >
Maintenance > Occupancy > BAS On/Off is set to either Unoccupied or Occupied.

Optimal Start Type – The method used to change from unoccupied to occupied
setpoint.
Options:
None* – Unit will not change to occupied setpoint until the scheduled time or the unit
goes into an occupied mode. Setpoints do not ramp, but change immediately from
unoccupied to occupied values.
Temp Compensated* – Unit changes to occupied setpoints at a variable time prior to
the occupied time, which is calculated by the current difference between space
temperature and the appropriate heating or cooling setpoint. At that time, the setpoints
do not ramp, but change immediately from unoccupied to occupied values.
Learning Adaptive Start – Unit gradually changes to occupied setpoints by adjusting the
unoccupied setpoints over a specified period of time to achieve the occupied setpoint
by the time scheduled occupancy begins.
