Multiple Boiler Control

If the demand is for space heating the controller typically determines its target temperature using outdoor reset logic.

Multiple boiler control.

A tekmar 275 should do fine. Select your level of control classic stage multiple heat sources to provide outdoor temperature reset for hydronic heating and domestic hot water generation. Performance use tekmarnet communication to stage multiple heat sources optimize system operation and provide remote monitoring and alerts capability. Selecting multiple boilers maximizes your energy savings and provides.

Modern microprocessor based controls for multiple boiler systems often perform several functions. Master and central control of multiple boilers for overall system load control reduces boiler on off cycling due to system load management incorporates lead lag or unison modulation for steam or hot water boiler systems. The utica boilers multiple boiler control mbc operates up to four boilers and resets the heating system water temperature based on outdoor air temperatures. It can be used in applications ranging from a single zone of baseboard multiple baseboard and fan coil zones to dedicated domestic hot water heating in commercial buildings.

You can then use outdoor reset and indoor reset. There are numerous bus architectures available. With a multiple boiler programmable controller such as the merley sequence controller the appropriate number of boilers can be set up to fire and modulate together to accurately respond to variations in demand in the most efficient manner in this way we can increase overall plant efficiency with improved load matching of the entire boiler plant to the building s. Boiler staging if you use a tekmar control that should do the job.

Complex boiler control systems may involve multiple digital control systems e g. In multiple parallel boiler arrangements the plant master must output to each boiler s combustion controls. I like indoor reset over outdoor reset for multiple reasons. That control will also rotate the boilers.

The communication data bus passes significant data between the digital control systems in a serial format. Alternate supply of the multiple boiler sequencer is the ems using modbus or 4 20ma as discussed above or a third party device such as manufactured by tekmar or heat timer. Dcs plc or computer controlled smart instruments linked together by a communication data bus. For starters they automatically calculate the proper supply water temperature to the system.

The boiler control 274 is designed to stage multiple boilers using outdoor temperature reset.
