7.3.1 E1 and E3
402 operates with 4 different energy formulas, E1, E3, E8 and E9, which are all calculated parallel with
each integration no matter how the meter is configured. E8 and E9 solely form the basis of the calculation of
average temperatures in forward and return pipes, whereas E1 and E3 are used for heat and cooling measurement
respectively.
Energy types E1and E3 are described by application examples below.
402-Vxxxxxx2xx or 402-Wxxxxxx2xx
Application A
Closed heating system with 1 flow sensor
Heat energy: E1 = V1(T1-T2)k
T1:Forward or T2:Return
Flow sensor V1 is placed in flow or return as
selected during PROG.
(Heat meter with MID marking and
Pt100 or Pt500 sensor inputs)
402-Txxxxxx5xx
Closed cooling system with 1 flow sensor
Application B
Cooling energy: E3 = V1(T2-T1)k
T1:Forward or T2:Return
Flow sensor V1 is placed in flow or return as
selected during PROG.
(Cooling meter with condensation protection and
Pt500 sensor inputs)
402-Txxxxxx6xx
Closed heat/cooling system with 1 flow sensor
Application C
Heat energy: E1 = V1(T1-T2)k
T1:Forward or T2:Return
Cooling energy: E3 = V1(T2-T1)k
T1:Forward or T2:Return
Flow sensor V1 is placed in flow or return as
selected during PROG.
(Heat/cooling meter with condensation
protection and Pt500 sensor inputs)
