On all previous software, the Heat Limit Switch would lockout both heating and cooling operation. An option to allow cooling operation while the Heat Limit Switch is in Alarm would allow the unit to cool as needed without risk to heat fault behaviors.

A user configuration option has been added which allows cooling functionality to ignore the Heat Limit Switch.

Enable Point Cooling Allowed During Heat Limit (CoolDuringHeatLimit).
