 – 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.

 – 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 
 – Minimum separation that must be maintained between the heating 
and cooling setpoints.
 
R:  _°F/C 
 – 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. 
 Optimal Start is automatically disabled when occupancy is controlled by a network write to 
the controller's keypad_ovrde variable. (Display name:
