Control module's function

SMO 20 is a simple control module, which, together with an
NIBE air/water heat pump, accumulator/water heater and
additional heating (e.g. electric/gas boiler), creates a com-
plete installation. Among other things, it controls the heat
pump, circulation pumps, reversing valves and step-con-
trolled additional heat to supply your home with environment-
ally friendly heating in the most efficient way.
