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
Min Setpoint Separation
– Minimum separation that must be maintained between the
heating and cooling setpoints.
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 occupancy is controlled by a
network write to the controller's keypad_ovrde variable. (Display name:
