For starters they automatically calculate the proper supply water temperature to the system.
Multiple steam boiler controls.
The three elements are water flow airflow and fuel flow.
The mpc or mpcq platinum are steam cycling controls for single boiler or multiple boiler steam heated buildings.
Tekmar is a great control but.
All boilers require control of three basic elements to operate safely and efficiently.
For steam boilers water flow is used to maintain the drum level.
Modern microprocessor based controls for multiple boiler systems often perform several functions.
They run steam cycles which are normally 60 minutes long the length of the cycle depends on the type of radiation in the system.
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.
This is a project for a high school and the controls have to tie into their existing bacnet temperature control system.
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.
