EE=12 Flow-controlled tariff
If the current water flow (Q) exceeds TL2, but is lower than or equal to TL3, energy is counted in TA2 parallel to the
main register. If the current water flow exceeds TL3, but is lower than or equal to TL4, energy is counted in TA3
parallel to the main register. If the current water flow exceeds TL4, energy is counted in TA4 parallel to the main
register.

Setting up data, TL3 must be higher than TL2 and TL4 must be higher than TL3.
The flow-controlled tariff is e.g. used as a basis for the individual heat consumer’s connection fee. Furthermore, this
tariff type can provide valuable statistical data if the heating plant considers new construction activities.
When either power or flow tariff is used, you obtain an overview of the total consumption compared to the part of
the consumption used above tariff limits.
EE=13 t1-t2 tariff (
∆
Θ
)
If the current t1-t2 (
∆
Θ) is lower
than TL2, but exceeds or is equal to TL3, heat energy is counted in TA2 parallel to
the main register. If the current cooling becomes lower than TL3, but is higher than or equal to TL4, energy is
counted in TA3 parallel to the main register. If the current t1-t2 (
∆
Θ) is lower than TL4, energy is counted in TA4
parallel to the main register.

Setting up tariff limits, TL3 must be lower than TL2 and TL4 must be lower than TL3.
The t1-t2 tariff can be used as a basis for weighted user charge. Low
∆
Θ (small difference between inlet and outlet
temperatures) is uneconomical for the heat supplier.
