Annex B
Fig. B1. 4-wire connection method for temperature sensors
T1 … T5
-
temperature sensors V1 …
V5 - flow sensors p1 ... p2 -pressure sensors
F1…Fi –
pulse outputs
Remarks: 1. Only required for selected measurement scheme sensors should be connected
2. Pressure sensors presented in this diagram are powered from separate power source.
Other options are presented in Fig. B3.
3.
Flow sensor V2 connection diagram for energy measurement algorithm “3
– winter / summer” is presented in Fig. B5. In this case flow sensor V4 not available.
4
. Diagram for connecting the regulating valve is presented in Fig. B4.
