Zone Controls for Pumps and Valves
August 15, 2017 | By HPAC Magazine
Caleffi Z-one Zone Controls for pumps, valves or both, have ample room for terminations, large screw terminals, automatic resettable fuse and snap-in transformers. These controls are compatible with two-, three- and four-wire zone valves and thermostats and have configurable pump logic. Application versatility is enhanced by three selectable 120 VAC auxiliary switches for enabling pumps and boilers, dedicated pump outputs and unlimited zone expansion. The single-zone pump control mounts to a 4 in. by 4 in. junction box.
