Unison Sohrana Troubleshooting
Unison Sohrana Sensor are simple 120/277 line level standalone sensors. They are configured with dip switches and dials. If you are having 0-10v control issues you should follow standard 0-10v troubleshooting. Some drivers can send some high voltage AC current (leakage) down the 0-10v wires. This can typically be seen between each 0-10v wire and ground.
