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.
