Refrigeration request 0..10 V
To be able to transmit a temperature request (for room cooling) to a refrigera-
tion request 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 are interpolated in a linear way.
Temperature requests above the selected temperature request threshold are
not forwarded to the heat demand controller (0 V).
