The MPC will work with virtually any non-vacuum steam heated system. The MPC can control a boiler directly to create steam. For systems where a central plant provides steam, the MPC opens or closes a motorized valve, to allow or prevent steam from entering the heating system. The MPC will also work with one or two-pipe steam systems.
