Tariff control (optional)

10 Tariff control (optional)

Threshold value tariff (tariffs T2, T3, T4, T5, T6)

W
V
Tariff situations "T2", "T3", "T4", "T5", "T6"

Supplied quantity of energy (tariff T7)

Returned quantity of energy (tariff T8)

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 situation.
The following options are available for tariff control:
The threshold value tariff can be derived from

the flowrate (tariff T2),

the power (tariff T3),

the temperature cold side (tariff T4),

the temperature warm side (tariff T5) or

the temperature difference (tariff T6).
The total heat quantity and the total volume are always summed. But the heat
quantity or the volume can also be acquired dependently from threshold value
in up to 3 tariff register.
Each tariff threshold is assigned its own tariff register.
Accumulated measured value:
W or V
Standard registers:
Heat quantity
Volume
Measured quantities for threshold values:
Q / P / TV / TR / TDiff
Summation in the relevant tariff register is only performed if the relevant
threshold is exceeded.

Threshold 1 exceeded: Summation in tariff register 1

Thresholds 1 and 2 exceeded: Summation in tariff register 2

Thresholds 1, 2 and 3 exceeded: Summation in tariff register 3
In tariff register 1, a quantity of energy is summated that is calculated from the
temperature warm side (instead of from the temperature difference).
In tariff register 1, a quantity of energy is summated that is calculated from the
temperature cold side (instead of from the temperature difference).
Tariff registers:
Threshold 1
TR1
Threshold 2
TR2
Threshold 3
TR3
34/49
Summation is performed, if:
Threshold 1 < Meas. value < threshold 2
Threshold 2 < Meas. value < threshold 3
Threshold 3 < Meas. value
