M2
r
Heating circuit pump of the heating
circuit with mixer M2/HC2
Connect a temperature limiter in series to restrict the
maximum temperature of underfloor heating circuit (if
installed).
Note
In systems without heating water buffer cylinder the
temperature limiter is connected to X3.2/X3.14 at the
luster terminals: See chapter "Temperature limiter to re-
strict the maximum temperature of underfloor heating
circuit".
