Electro Industries 4 Zone Controller with Enclosure

The zone controls are designed to simplify wiring and enhance system performance by communicating zone information to the TS Series boilers. With unique “dial a BTU” switch, adjusting the BTU’s required for each zone is easy and allows the boiler to quickly adapt to the changing flow rates of different size zones. Optional Zone 1 priority allows heat to Zone 1 only. When two different water temperatures are desired for your system, switch to high temp priority and the boiler will increase output temperature to 155 degrees or 180 degrees for Zone 1. This allows you to direct pipe to radiant floor manifolds and a baseboard, radiator zone, or indirect domestic hot water tank. This can eliminate temperature mixing valves and simplify system piping.

Features:

• For applications of up to 4 zones, designed to control zone valves only
