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 3, 4, 5 and 6 zones.
