If the indoor temperature is greater than the desired temperature plus one degree, then:

AB = AB + HA

Where:

AB

=

Adjust begin time from SSTO command.

HA

=

Heating auto-tune coefficient (hcoef4) from SSTOCO command.

If the indoor temperature is less than desired the temperature minus one degree, then:

AB = AB - HA

Where:

AB

=

Adjust begin time from SSTO command.

HA

=

Heating auto-tune coefficient (hcoef4) from SSTOCO command.
