If the indoor temperature is less than the desired temperature, then the optimum stop time is:

OE + ((10 * CR * d)/f) + AE

Where:

OE

=

Occupancy end time from SSTO command.

CR

=

Cooling retention coefficient in hours (ccoef2) from SSTOCO command.

d

=

Indoor temperature minus the desired temperature.

f

=

Outdoor temperature minus the desired temperature.

AE

=

Adjust end time from SSTO command.

If the indoor temperature is greater than or equal to the desired temperature, the optimum stop time is LE:

Where:

LE

=

Latest end time from SSTO command.
