During the initial or rerunning the commissioning of the
system using the iComfort S30 Ultra Smart thermostat, the
system will auto-detect the presence of the
PureAir
S
unit.
Follow the instructions provided with the thermostat for the
system commissioning process. If the PureAir
S
component
is successfully detected, it will appear on the found
equipment screen.
NOTE:
During commissioning the blower will turn on and
run at three different CFM settings for the PCO
filter calibration to take place. This may be well in
advanced before the display is fully up and running.
This is a normal process. The blower may run as
long as 90 seconds at each CFM setting to complete
the filter calibration .
