* - For these diagrams it is provided tariffing (and measurement of energy for cooling) function.
In this case it is possible to apply to the second heating system only the scheme U0.

First heating system U1, U2, U3, A1, A2, A3, A4 V1, V2 T1, T2, T5
Second heating system U0, U1, U2 V3, V4, V5 T3, T4
Note: Pressure sensors (p1,p2) are intended for the application in any heating system
Measurement diagrams and energy calculation formulas are provided in the Table 1. Flow,
temperature and pressure measurement channels that are not used for heat energy measurement can be
used to monitor other parameters. Measured volume can be converted into weight expression, using
practically measured flow temperature.
