Tekmar 275 | Boiler Control - One tN4, Four Modulating Boiler & Dhw / Setpoint

Tekmar 275 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.
