Boiler Control- One tN4, Four Modulating Boiler & DHW/Setpoint


The boiler control 275 is designed to stage up to four condensing or non-condensing, modulating or on-off boilers using P.I.D. staging to accurately maintain temperature. Water temperature is controlled by outdoor temperature reset for space heating applications or a fixed setpoint for domestic hot water (DHW) tank heating or industrial process heating applications. The control will also accept an analog 0-10 V (dc) signal from an energy management system (EMS) to control the water temperature. Boiler equal run time rotation, pump exercising and stand-by system pump operation increase boiler plant reliability. The control is tekmarNet® communication compatible allowing for internet connectivity using an optional Gateway 483.
