1) Low temperature heating
maximum flow temperature 50 °C,
minimum flow temperature 20 °C,
average operating temperature (50 + 20) : 2 = 35 °C;
The operating point of the operating characteristic curve is to
be set at 35 °C.
2) Ventilation and air conditioning systems:
maximum supply temperature 40 °C
minimum supply temperature 20 °C
average operating temperature (40 + 20) : 2 = 30 °C
The operating point of the operating characteristic curve
is to be set at 30 °C.
3) Mixing chamber:

When using separated temperature sensors and target va -
lue setting devices (TW 21...23), the function selector on
the back of the control unit S2 is to be set always on 1 .
These target value setting devices are gaged in °C.
