I am gathering from the replies that using a package multiple boiler controller has had more success than letting the temperature controls contractor provide the boiler controls.
Multiple steam boiler controls.
Multiple boiler control mbc amb4bub amb4bub the utica boilers multiple boiler control mbc operates up to four boilers and resets the heating system water temperature based on outdoor air temperatures.
In this case each boiler has its own boiler master which is an auto manual station that accepts the plant master s output applies a ratio and bias and sends the result out as the demand signal to the combustion controls.
In multiple parallel boiler arrangements the plant master must output to each boiler s combustion controls.
Tekmar is a great control but.
Modern microprocessor based controls for multiple boiler systems often perform several functions.
The three elements are water flow airflow and fuel flow.
If the demand is for space heating the controller typically determines its target temperature using outdoor reset logic.
All boilers require control of three basic elements to operate safely and efficiently.
For starters they automatically calculate the proper supply water temperature to the system.
The mpc or mpcq platinum are steam cycling controls for single boiler or multiple boiler steam heated buildings.
