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.
