Taco Zone Valve Controls work with two-, three-, or four-wire zone valves. All are fuse protected; it also includes two isolated end switches and a built-in priority switch. The contractor friendly PC board layout eliminates incorrect wiring and the "unfinished" look of conventional zone valve installations. The sturdy screw connections add even more reliability, while the external indicator lights provide instant diagnostic feedback to reduce installation time and troubleshooting. For those larger jobs, the -EXP controls can be expanded up to 120 zones with priority. All Taco Zone Valve Controls are UL listed and are available in three, four, five, and six zones. External Diagnostics: The indicator lights show full functionality of the products wired to the zone valve control. The green light indicates power is connected. When the thermostat calls for heat, both the appropriate zone valve and yellow indicating light are energized. When the zone valve is fully opened, the end switch relay and red indicating light are then energized. The Taco Priority Zoning Circulator can be used in conjunction with other circulators or zone valves, and is ideal for indirect hot water heaters, adding another zone, zoning with circulators, and for prioritizing under-sized zones.
