Tariff control (optional)
Note:
The tariffs can only be parameterized using the service
software.
Note:
The summation of quantity of energy and volume in the
standard registers is performed independently of the tariff situa-
tion.
The following options are available for tariff control:
Threshold value tariff (tariff T1 - T5, T9
– T13)
The thresholds S1, S2 and S3 can be derived from:
•
flow rate (tariff T1, T9),
•
power (tariff T2, T10),
•
temperature cold side (tariff T3, T11),
•
temperature hot side (tariff T4, T12) or
•
temperature difference (tariff T5, T13)
For the tariffs T1 - T5, the energy is added to the tariff registers while for the
tariffs T9 - T13 the same is done for the volume.
Fig. 13: Threshold value tariffs
Summation in the relevant tariff register is only performed if the relevant
threshold is exceeded.
•
Threshold 1 exceeded: Summation in tariff register 1
•
Threshold 1 and 2 exceeded: Summation in tariff register 2
•
Threshold 1, 2 and 3 exceeded: Summation in tariff register 3
Supplied quantity of energy (tariff T6)
In tariff register 1, the energy is summated up, which is calculated from the
temperature hot side and the reference temperature.
Returned quantity of energy (tariff T6)
In tariff register 1, the energy is summated up, which is calculated from the
temperature cold side and the reference temperature.
Heat / cooling meter (tariff T7)
In tariff register 1, the measured quantity of cold; in tariff register 2, the meas-
ured quantity of heat is summated. In both cases a threshold can be defined
via the temperature hot side (“cold threshold”, “heat threshold”).
