If the indoor temperature is less than the desired temperature, then the optimum start time is LB.
Where:
LB | = | Latest begin time defined in the SSTO command. |
If the indoor temperature is greater than or equal to the desired temperature, then the optimum start time is:
OB - (d * CC) - (d * f * (CT/10)) + AB
Where:
OB | = | Occupancy begin time from SSTO command. |
d | = | Indoor temperature minus the desired temperature. |
CC | = | Cooling coefficient (ccoef1) from SSTOCO command. |
f | = | Outdoor temperature minus the desired temperature. |
CT | = | Cooling transfer coefficient (ccoef3) from SSTOCO command. |
AB | = | Adjust begin time from SSTO command. |
