Compressor Short
Cycle Delay
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
short cycle delay, the outdoor unit control’s seven segment display
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).
Dehum Airow
Adjustment Adder
Dehumidication airow = “HUMID” Mode CFM table value for a
given thermostat demand + dehumidication adjustment adder
(High Normal Cooling Airow CFM x Dehumidication Airow
Adjustment Adder in percentage. Both these values are in the
installer set up under System Device/Air Conditioner/High Normal
Cooling Airow).
Equipment Name
A unique name can be assigned to this component. Name can be
up to 29 characters. Name can consist of letters, numbers, special
characters and spaces.
High Normal
Cooling Airow
(Lennox Variable
Capacity Air
Conditioners Only)
The range is 450 - 2150 CFM. Default is dependent on unit
capacity with an incremental adjustment of 25 CFM.
Thermostat values shown are defaults. This value can be adjusted
up or down to meet each application requirements.
Low Normal
Cooling Airow
(Lennox Variable
Capacity Air
Conditioners Only)
The range is 450 - 2150 CFM. Default is dependent on unit
capacity with an incremental adjustment of 25 CFM.
Thermostat values shown are defaults. This value can be adjusted
up or down to meet each application requirements.
Reset Air
Conditioner
Any installer modications under the air conditioner tab will be
reset back to the factory defaults if the reset air conditioner option
is used.
Zoning Control

Parameter Description
About
This provides information on unit code, language supported,
equipment type name, control software revision, control model
number, control serial number, control hardware revision, protocol
revision number, device product level, 24VAC average power
consumption, 24VAC peak power consumption, compatible devices
list, application code memory size, micro-controller part number,
max number of zones, supported damper types, number of damper
positions, zone temp sensor 1, zone temp sensor 2, zone temp
sensor 3 and zone temp sensor 4.
Equipment Name
A unique name can be assigned to this component. Name can be
up to 29 characters. Name can consist of letters, numbers, special
characters and spaces.
Zones 1 through
4 Temp Reading
Calibration
Allows adjustment to temperature reading displayed on zone
thermostat.
Reset Zoning
Control
Any installer modications under the zoning control tab will be reset
back to the factory defaults if the reset zoning control option is
used.
PureAir S
Table 12. PureAir S Parameters
Parameter Description
Equipment PureAir Filter
Dirty Filter
Detection and UV
Life Detection
Default: ON. Options are either ON or OFF.
This parameter turns on and off the lter life and UV lamp life
reporting. When set to off, the control will continue to calculate
the remaining lter life through continuous sampling, but will not
use lter tests to determine lter life. The control will:
• Perform a lter calibration upon indication of a lter change
regardless of the value of this parameter.
• Perform a UVA lamp calibration upon indication of a lamp
change regardless of the value of this parameter.
• 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 lter life and UV lamp life regardless of the value
of this parameter.
