7.6 Tariff functions
MULTICAL
401 has two extra energy registers TA2 and TA3, which accumulates energy parallel to the main
register on the basis of an entered tariff condition. TA2 and TA3 always have the same measuring unit as the main
register (kWh, MWh or GJ), however, except from E=4
m
3
C.
Irrespective of the selected tariff, the unit field always indicates TA2 and TA3.
As it is considered legal accounting register, the main register is always accumulated irrespective of the selected
tariff function. The tariff conditions TL2 and TL3 are checked before each integration. When the tariff conditions
are fulfilled, the thermal energy used is accumulated in either TA2 or TA3 parallel to the main register.
Each tariff function has two connected tariff conditions, TL2 and TL3, which are always used in the same tariff
type. Therefore, it is imposible to ”mix” two tariff types.
Below table indicates, which tariff types MULTICAL
401 can be configured into:
E= Tariff type Function
0 No tariff active No function
1 Power tariff Energy will be accumulated in TA2 and TA3 based on the power limits in TL2 and TL3
2 Flow tariff Energy will be accumulated in TA2 and TA3 based on the flow limits in TL2 and TL3
3 Cooling tariff
Energy will be accumulated in TA2 and TA3 based on the t-limits in TL2 and TL3
