Description
Set AI1 (duct sensor) input signal:
Display shows
humidity sensor .
If duct sensor is not installed select the default setting, OFF .
To configure the duct sensor as the primary control sensor (installed in the return
duct) select EHS.0 .
To configure the duct sensor as the high humidity limit sensor (installed in the
supply duct) Select HIL.0 .
If you have selected OFF or SPS, go directly to Step 20.

NOTE: If SPS is selected, the dehumidify set point will be disabled .
External humidity sensor offset calibration:
(If EHS.0, EHS.2, HIL.0 or HIL.2 has been selected at Step 17 . )
Display shows

percentage read by duct humidity sensor . Humidify symbol is also displayed .
If the sensor is not connected or short circuited, the display shows Eror .
You can adjust the calibration of the sensor by comparison with a known
humidistat .
Adjust high limit set point:
(If HIL.0 or HIL.2 has been selected at Step 17 . )
Display shows
