CoolTime is the amount of time within CycleTime that the cool output is to be
turned on.
If CoolTime < MinCoolTime, set CoolTime = 0.
If CoolTime > MaxCoolTime, limit CoolTime = MaxCoolTime.
CoolTimePercent is the percentage of CycleTime that the CoolOut pulse is true.
The instruction controls heat and cool outputs using these rules:
•
Set HeatOut to true if HeatTime
Clear HeatOut to false when the internal cycle timer > HeatTime.
•
Set CoolOut to true if CoolTime
Clear CoolOut to false if the internal cycle timer > CoolTime.
•
Clear HeatOut and CoolOut to false if CycleTime = 0.
