Digital Input to Initiate Remote Calibration Unit
The digital input connections on the
Wiring
board allow you to initiate a
calibration from a remote location. For this option to work, you must have a
remote calibration unit. The system monitors the digital input, and when the
switch closes, it sends the system into an automatic calibration. The switch you
connect to this digital input must be a normally open switch.
