Effective Setpoints
The Effective Setpoints graph shows the current occupied or unoccupied setpoints. If occupied, these values are the current
programmed setpoints plus the offset of any setpoint adjustment that may be in effect. If unoccupied, the values are the
programmed unoccupied setpoints.
Point Name/Description Default/Range
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
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
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.
