Add a connection to a valve operator in Settings, under the
Connection tab.
Before connecting to a valve operator, turn its power on.
1. Tap the Vitals Mobile-TC Settings icon. The Connection
tab appears by default.

2. Tap the icon for MANAGE EQUIPMENT to display available
valve operators (both paired and unpaired). Make
sure the valve operator is turned on.

3. Tap the PAIR button for the valve operator you want to
connect to. A Scanning... message appears on the MY
CONNECTION and MY EQUIPMENT sections while the
connections are updated.

4. The updated connections are listed. To change the
active connection, select the new valve operator under
MY EQUIPMENT.

Vitals Mobile will try to connect only to the device listed under MY CONNECTION. If different machine is desired it will need to be moved to the MY CONNECTION section by selecting it from the MY EQUIPMENT section (if it was already paired, otherwise pair first under MANAGE EQUIPMENT).
Go to the controller screen and it should connect to the machine.
