Functions
■ Electronic maximum and minimum temperature limit
■ Demand-dependent shutdown of the heat pump and the pumps for
the primary and secondary circuits
■ Adjustment of a variable heating and cooling limit
■ Pump anti-seizing protection
■ Monitoring frost protection of system components
■ Integral diagnostic system
■ Cylinder temperature controller with priority control
■ Auxiliary function for DHW heating (short-term heating to a higher
temperature)
■ Control of a heating water buffer cylinder
■ Screed drying program
■ External hook-ups: Mixer OPEN, mixer CLOSE, changeover of
operating mode (with external EA1 extension, accessories)
■ External demand (adjustable set flow temperature) and heat pump
blocking, specifying the set flow temperature via an external 0 to
10 V signal (with external EA1 extension, accessories)
■ Function check of controlled components, e.g. circulation pumps
■ Optimised utilisation of power generated by the photovoltaic sys-
tem (on-site power consumption)
■ Control and operation of compatible Viessmann ventilation units
