5.3.5 Group 5 Comfort Settings

Enable Dehumidification

[Enable], Disable

When dehumidification is enabled, the control will reduce system 
airflow by 30% (variable speed indoor units only) anytime the indoor 
humidity is higher than the cooling target humidity setpoint and the 
indoor temperature is within 2°F of cooling setpoint. All fan off delays 
will also be cancelled.

Dehumidification Overcooling Limit - Degrees

[0°] - 3°F

Select the maximum amount of overcooling allowed when the indoor 
humidity exceeds the cooling target humidity setpoint. To accomplish 
the overcooling the control will artificially create additional load by 
increasing the sensed indoor temperature by 1/10th of a degree for 
every 1% of a percent of humidity error, up to the overcooling limit 
selected. The displayed indoor temperature will remain the same, but 
the adjusted indoor temperature will control cooling operation.

Control Response Rate

[Normal], Fast

Select how quickly the control builds load value (Selecting Fast will 
cause the control to build load value faster than normal operation)

Aggressive Recovery > 2° Setpoint Change

Enable, [Disable]

Select whether the 10-minute staging inhibit is disabled (heating or 
cooling mode) with a setpoint change greater than 2°F (Change can 
be manual or scheduled)

Heating Aggressive Recovery

Enable, [Disable]

Select whether the 10-minute staging inhibit is disabled during heating 
mode when the outdoor temperature falls below the selected outdoor 
temperature  (Outdoor temperature sensor must be connected and 
enabled to allow this setting to be selected)

Warm Air Discharge

Enable, [Disable]

When enabled the indoor blower speed will be limited to 80% on a call 
for heat pump heating. This only applies to heat pump heating with no 
call for aux heat (An indoor unit with variable speed blower is required)
