HPZC10*33-00360EF—05 6TROUBLESHOOTINGValve Fuse ProtectionThe Hydronic Zone Valve panels come equipped withautomatically resettable fuses on each valve output. Thisfuse will trip when a load of 3.7 Amps or higher is applied.Should one of the valves in a system fail shorted, thepanel’s Power Transformer Fuse will be protected and allother zones in the system will remain operational.It is recommended that power be removed from theHydronic Zone Valve Panel, before replacing a faulty zonevalve. This will accelerate the time required for the fuse toautomatically reset and return fully to its initial state.The following steps can be used to detect if a valve faulthas occurred:• Open panel cover• Slide Priority Switch position to OFF• Jumper terminals 3 and 4 on the suspect zone valveoutput• Give zone thermostat a call for heat• If the thermostat LED is ON and Valve LED is OFF, thepanel’s fuse has tripped (valve fault – short).• Slide the Priority Switch position back to its initialposition.NOTE: Before replacing a faulty valve, remember toremove power from the zone panel.Status LabelFig. 16.This panel provides a status indicator label which isavailable both when the panel cover is in place andremoved.
