Temperature 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 setpoint at 0 V and 10 V must be predefined for the
central apartment unit. The values in between is interpolated in a
linear way. Temperature requests below the selected temperature
request threshold is not forwarded to the heat demand controller (0 V).
