Tekmar Boiler Control-One tN4, Four Modulating Boiler & DHW/ Setpoint
Tekmar 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. The
275 can control mixed boiler plants that contain both condensing and
non-condensing
boilers.
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.
