CONFIGURATION | CONFIRMATION
Once paired, ensure that the sensor is reading accurately. To do this
you will go to the Central Control Unit (CCU), or the 75F installer app
on your iPhone or Android device to look at the pressure value. On
the CCU go to the Zones tab and see the Pressure reading in
“W.C.
Check that the value is not maxed out in either direction, +0.25wc or
-0.25wc.
To look at the summary page on the CCU tap on the 75F logo in the
upper left 4 times and a new tab will appear titled Summary.
In the Summary tab look at the Pressure Sensor section and check
that there are rational values being displayed for the differential
pressure. Typical differential pressure values under static conditions
should be 0.0
inches’
water column, +/- 0.05 is acceptable under
static conditions. If there are no values, check that the Pressure
Sensor Controller is paired correctly, and check that the connections
to the sensor are color coded correctly and are firmly plugged in to
their terminals. Hide the Summary tab again by pressing the logo
until it disappears.
