6-Zone Valve Control w/ Priority, Expandable
Brand: Taco
Part#: ZVC406-EXP-4
Taco ZVC406-EXP-4 is a 6-Zone Valve Control (Expandable up to 20 Zones). This model works with 2, 3 or 4-wire zone valves, is fully fuse protected and includes two isolated end switches and a built-in priority switch. The easy to read PC board layout of the Taco ZVC406-EXP model eliminates problems with incorrect wiring and the “unfinished” look of conventional zone valve installations.
