- the dotted lines show the signal exchanges between the control device 70 and the various elements of the system:
- the device 70 notably receives a plurality of temperature and pressure measurement signals coming from the different probes TT, PT, HT, etc., and The device transmits instructions back to the valves 36, 37, 44, 47, to the compressor 42, to the circulator 33, and so on.
