Heat/Cool Minimum On-times

Words 6 and 8 for channel 1

These values determine the minimum cycle time after which loop

TPO bits will turn ON. They are used to allow contactors time to close

or pull in. If the contactor is energized for less than this value, the

contactor will not close, but the attempt will count as a cycle.

For example, suppose you set the TPO period for 10 seconds and the

minimum ON time to 1 second. Then if the module calculates a CV%

of 10% or less, the TPO bit for that zone will not turn ON.

Heat/Cool TPO Period

Words 7 and 9 for Channel 1

When CV loop output is time–proportioned (TPO), use this value to

set the interval between successive turn–ONs. For less than a 100%

output level, the output goes OFF for the balance of the interval.
