If the indoor temperature is less than the desired temperature, then the optimum stop time is LE:
Where:
LE | = | Latest end time from SSTO command. |
If the indoor temperature is greater than or equal to the desired temperature, then the optimum stop time is:
OE - ((25 * HR * d) / f) + AE
Where:
OE | = | Occupancy end time from SSTO command. |
HR | = | Heating retention coefficient (hcoef2) from SSTOCO command. |
d | = | Indoor temperature minus the desired temperature. |
f | = | Outdoor temperature minus the desired temperature. |
AE | = | Adjust end time from SSTO command. |
