Heat Request 0..10 V - Siemens Synco living QAX913 Mounting And Commissioning

Heat request 0..10 V

To be able to transmit a temperature request (for space heating and DHW) to
a heat demand controller by means of a 0..10 V signal, the temperature set-
point at 0 V and 10 V must be predefined for the central apartment unit. The
values in between are interpolated in a linear way.
Temperature requests below the selected temperature request threshold are
not forwarded to the heat demand controller (0 V).
