Programming unit:
■ Display
■ Keys:
– Program selection
– Boiler water temperature
– DHW temperature
Functions
■ Constant control of the boiler water temperature
■ Electronic maximum and minimum temperature limit
■ Integral diagnostic system
■ Cylinder temperature control unit with priority control (heating circuit
pump OFF).
According to the [German] Energy Savings Order, a weather-com-
pensated or room temperature-dependent control unit with time pro-
gramming for reduced operation must be installed downstream of the
boiler (see Viessmann pricelist register 18 "Heating circuit control
units").
Control characteristics
■ P-characteristics with two-point output
■ Thermostat for limiting the max. boiler water temperature:
75 °C, adjustable to 87 °C or 95 °C
■ Adjusting the high limit safety cut-out:
110 °C, adjustable to 100 °C
Boiler coding card
For matching to the boiler (supplied with the boiler).
