"Ext. 0-10 V"
(external output signal)
■ The set value for the heating water buffer cylinder and heating circuits is specified
by an external analogue signal (0 V = -10 °C, 10 V = 73 °C or lower if the maximum
flow temperature for the selected heat pump is below this).
"External heating"
■ Optional external heating is switched on if the heat pump does not reach a certain
minimum flow temperature.
■ It is adjusted in the detailed system view of the booster heater.
"Heating zone 1-3"
■ Here you can set the number of heating circuits installed.
■ Each installed heating circuit appears in the system view. Adjustments to the
circuit are made one by one.
"Regulated"
■ A mixer must be installed for every regulated heating circuit.
■ The heating circuit has its own heating curve or its own set value.
■ If a circuit can also provide cooling, a choice between cooling or heating is
offered; it is not possible to select both.
