Heat-Timer’s HYBRID Mini-MOD-CNC control lets owners efficiently control condensing and noncondensing boilers simultaneously. The CNC automatically stages and/or modulates noncondensing and condensing boiler operation to optimize the efficiency of a combined system. Return on investment is faster due to the control automatically switching to high-mass boilers when the building heat requirements approach design loads. An extension module can be added for six additional stages (two extension modules can be added to one CNC for a total of 16 stages).
