They run steam cycles which are normally 60 minutes long the length of the cycle depends on the type of radiation in the system.
Multiple steam boiler controls.
For starters they automatically calculate the proper supply water temperature to the system.
If the demand is for space heating the controller typically determines its target temperature using outdoor reset logic.
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.
In multiple parallel boiler arrangements the plant master must output to each boiler s combustion controls.
This is a project for a high school and the controls have to tie into their existing bacnet temperature control system.
Tekmar is a great control but.
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.
All boilers require control of three basic elements to operate safely and efficiently.
Modern microprocessor based controls for multiple boiler systems often perform several functions.
