The Powered Four and Six zone Controllers feature transformers for low-voltage operations and relays to operate line-voltage controls. Fully fuse-protected, they also include an isolated end switch and built-in DHW priority switch. The indicator lights show full functionality of the products wired to the Powered Zone Controllers. The green light indicates power is connected. When the thermostat calls for heat, both the appropriate zone valve and yellow indicator light are energized. When the zone valve is fully open, the end switch relay and red indicator light are energized. A 3 amp delay fuse protects the Powered Four-zone Controller. A 7 amp delay fuse protects the Powered Six-zone Controller
