Comfort Cooling (Id10)
When comfort cooling is on, the indoor unit cooling coil target superheat value is
increased in steps as the space temperature approaches the setpoint temperature (rate
of outdoor temperature change and humidity influence the superheat adjustment). This
results in warmer chilled air coming from the indoor unit. The function extends cooling
operation run time. Comfort Cooling must be set on an indoor unit to indoor unit basis
unless the apply to all option is selected.
For use on both heat pump and heat recovery systems.
