This feature prevents the compressor from being short cycled
any time the compressor is turned "OFF". The range is 60 -
300 seconds. Default is 300 seconds and with an incremental
adjustment of 60 seconds. When the system initiates a compressor
Compressor Short short cycle delay, the outdoor unit control's seven segment display
Cycle Delay will show the delay in minutes from 1 to 5 minutes. The sequence is
time (minutes) remaining and a dash, and will repeat that cycle (5,
4, 3, 2 and 1) until the count down is complete. If the delay timer is
change for example to 180 seconds, then the countdown will start
at 3 (minutes).
Dehumidification airflow = "HUMID" Mode CFM table value for a
given thermostat demand + dehumidification adjustment adder
Dehum Airflow (High Normal Cooling Airflow CFM x Dehumidification Airflow
Adjustment Adder Adjustment Adder in percentage. Both these values are in the
installer set up under System Device/Air Conditioner/High Normal
Cooling Airflow).
A unique name can be assigned to this component. Name can be

Table 12. PureAir S Parameters
Parameter Description
Equipment PureAir Filter
Default: ON. Options are either ON or OFF.
This parameter turns on and off the filter life and UV lamp life
reporting. When set to off, the control will continue to calculate
the remaining filter life through continuous sampling, but will not
use filter tests to determine filter life. The control will:
• Perform a filter calibration upon indication of a filter change
regardless of the value of this parameter.
Dirty Filter
• Perform a UVA lamp calibration upon indication of a lamp
Detection and UV
change regardless of the value of this parameter.
Life Detection
• Calculate UVA lamp life remaining regardless of the value of
this parameter.
Alarms 504 and 503 will not be sent while this parameter is set
to "Off"
The Diagnostics screen on the thermostat will continue to show
values for both filter life and UV lamp life regardless of the value
of this parameter.
