For problems that fall into the second category, find out what has changed because these factors might provide
some insight or a place to start looking for solutions.
Repairing Device Assignments and Addresses
This process searches for and verifies communication with each of the devices on the two-wire.
Note: Baseline recommends that you back up your controller data before you run this process. Refer to Backing Up
Your System on page 71.
The Verify and Repair ALL process does not check the valve current or biSensor readings, and it does not repair any
faulty wiring or electrical connections. However, if it finds discrepancies in assignments or addressing between the
controller and the devices, it will attempt to repair those discrepancies in the following order:
• Repair valve biCoder to zone number assignments
• Repair biSensor addressing
• Repair pause device addressing
• Repair air temperature sensor addressing
1. Turn the dial to the Self-Test position.
2. Press the NEXT or PREV button to select Verify and Repair ALL, and
then press the ENTR button. The Verify and Repair ALL process begins.
When the Verify and Repair ALL process is finished, the controller
displays the Self-Test menu.
3. When you have finished viewing the test results, return the dial to the
Auto Run position.
Troubleshooting the Two-Wire: High Current or Shorted
The first step in troubleshooting the two-wire is to isolate what works from what does not work. A complex system
with many branches in the two-wire path can be difficult to troubleshoot while everything is interconnected.
When a short can be isolated to a single segment of the two-wire system, or to a single component, it becomes
much easier to fix the problem.
In order to isolate the short, you must physically disconnect two-wire segments and components from the system
in a logical manner. Then you can add the two-wire segments and components one at a time in order to isolate the
problem.
• Begin by disconnecting half of the two-wire.
• Next, determine whether the system is running properly with just half of the two-wire connected. If it is, you
know that the short is in the other half of the two-wire. If the system does not run properly, you know that the
problem is in the half of the two-wire that is connected.
• After you have isolated the short to a half of the two-wire, you can start breaking connections, one at a time,
in order to isolate exactly where the problem is.
• After you isolate the short, you need to find out what changed recently that may have caused the problem.
