Changing Jumper Positions (Averaging reading from Remote Sensor)
If using multiple Remote Temperature/Humidity sensors in your application, refer to the
photos showing the need to change the jumper locations internal to the control board on each
remote sensor (up to 3 maximum).
For the control to average all of the sensors utilized (if more than
one), the jumper must be in different positions on the pins.
As you can see, there are three pin settings. To access the
jumper:
1. Remove the two-set screws holding on the plastic cover. This procedure allows the control to
go to each remote sensor in sequence to average. Failure to perform this procedure will
result in the system reading only one sensor and not the average of multiple sensors.
NOTE: If multiple sensors control the WG unit, change factory default in configuration
setting 10 to “averaging.” You will need access code from Air Innovations service to use
in configuration 8 to reach configuration 10.
