The Mini-MOD-CNC lets owners effectively and efficiently control a boiler system that utilizes both condensing and noncondensing boilers. It automatically mixes and matches noncondensing boiler operation and condensing boiler operation to optimize efficiency of a combined system. According to the manufacturer, the control also allows for mixed control of modulating and staging boilers since condensing boilers typically have modulating burners and noncondensing boilers typically have staging or on-off burners. The control automatically switches to high mass boilers when the building heat requirements approach design loads, so high-mass boilers operate when they are most efficient (at peak loads) and condensing boilers operate when they are most efficient (at part load).
