Taco®, ZVC404-4, Zone Valve Control, Series: ZVC, 4 Zones, 120 VAC, 1/6 hp Power, DPDT Contact Form, For Use With: System Pump, 7 in Height, 10-3/4 in Width, 2-3/4 in Depth, Domestic
Taco Zone Valve Controls work with two-, three-, or four-wire zone valves. Fully fuse protected, they also include two isolated end switches and a built-in priority switch. The contractor friendly PC board layout eliminates the problems caused by incorrect wiring and the unfinished look of conventional zone valve installations. The sturdy screw connections add additional reliability, while the external indicator lights provide instant diagnostic feedback, reducing installation time. All Taco Zone Valve Controls are UL and CSA listed and carry an extended 3 year warranty.
- Operation/external diagnostics - when any thermostat calls for heat, the appropriate zone valve is energized and the yellow light goes on
- When the zone valve is fully open, the red light goes on and energizes the end switch relay
- The green light should always be on, indicating that power is connected
- Priority operation - when zone 4 is switched to the priority setting and is actuated, all other zones will stop operation until zone 4 is satisfied
- When a circulator is used on the priority zone instead of a zone valve, jumper 3 and 4 of the priority zone
- Priority protection operation - when the priority zone calls continuously for more than one hour, power is returned to all the other zones, allowing each zone to function independently
- Once the priority zone is satisfied, the control's auto-reset is activated and the priority zone is again allowed to have priority for up to one hour starting from when it calls next
- External Indicator Lights
- Switchable Priority
- Simplified Wiring
- Works with 2, 3, or 4-Wire Zone Valves
- Compact Design
- Fuse Protected
- 100% Factory Tested
- Two Isolated End Switches
- Extra Set of Dry Contacts
