Multi-Boiler Rotation

Our newest controller firmware release now offers boiler rotation logic that you can use to control the firing sequence of heating systems that use more than one identical boiler.

Multiple boilers are normally fired sequentially, as the heating demand increases. For example, Boiler No. 1 might be programmed to turn on when the total heating demand is less than 15 percent. Boiler No. 2 might be programmed to turn on when the heating demand ranges between 15 percent and 30 percent and so on. This sequence is often fixed. The new Multi-Boiler Rotation program allows you to manually or automatically rotate the boiler firing sequence to achieve even wear on your system components. In addition, individual boilers can be taken out of service for maintenance without major changes to your control configuration. Up to 24 individual boilers can be operated as a single managed group. Each boiler can control a circulation pump and up to 4 managed stages or firing levels.

If you require multi-boiler rotation control, call your Argus reseller or Argus.
