Refer to Backing UpYour System on page 71.The Verify and Repair ALL process does not check the valve current or biSensor readings, and it does not repair anyfaulty wiring or electrical connections. However, if it finds discrepancies in assignments or addressing between thecontroller 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 addressing1. Turn the dial to the Self-Test position.2. Press the NEXT or PREV button to select Verify and Repair ALL, andthen press the ENTR button. The Verify and Repair ALL process begins.When the Verify and Repair ALL process is finished, the controllerdisplays the Self-Test menu.3. When you have finished viewing the test results, return the dial to theAuto Run position.Troubleshooting the Two-Wire: High Current or ShortedThe first step in troubleshooting the two-wire is to isolate what works from what does not work. A complex systemwith 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 becomesmuch easier to fix the problem.In order to isolate the short, you must physically disconnect two-wire segments and components from the systemin a logical manner. Then you can add the two-wire segments and components one at a time in order to isolate theproblem.• 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, youknow that the short is in the other half of the two-wire. If the system does not run properly, you know that theproblem 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.
