TROUBLESHOOTING

Valve Fuse Protection

The Hydronic Zone Valve panels come equipped with
automatically resettable fuses on each valve output. This
fuse will trip when a load of 3.7 Amps or higher is applied.
Should one of the valves in a system fail shorted, the
panel's Power Transformer Fuse will be protected and all
other zones in the system will remain operational.
It is recommended that power be removed from the
Hydronic Zone Valve Panel, before replacing a faulty zone
valve. This will accelerate the time required for the fuse to
automatically reset and return fully to its initial state.
The following steps can be used to detect if a valve fault
has occurred:
• Open panel cover
• Slide Priority Switch position to OFF
• Jumper terminals 3 and 4 on the suspect zone valve
output
• Give zone thermostat a call for heat
• If the thermostat LED is ON and Valve LED is OFF, the
panel's fuse has tripped (valve fault – short).
• Slide the Priority Switch position back to its initial
position.
NOTE: Before replacing a faulty valve, remember to
remove power from the zone panel.
