EE=13 T1-T2 tariff (
∆
t)
If the current T1-T2 (
∆
t) is lower than TL2 but exceeds TL3, the energy is counted in TA2 parallel to the main
register. If current cooling falls below or is equal to TL3, the energy is counted in TA3 parallel with the main
register.

Setting up tariff limits TL3 must always include a higher value than TL2.
The T1-T2 tariff can be used as a basis for weighted user charge. Low
∆
t (small difference between forward and
return temperatures) is uneconomical for the heat supplier.
E=14 Forward temperature tariff
If the current forward temperature (T1) exceeds TL2 but is lower than or equal to TL3, the energy is counted in TA2
parallel to the main register. If the current forward temperature exceeds TL3, the energy is counted in TA3 parallel
to the main register.

Setting up data TL3 must always include a higher value than TL2.
The forward temperature tariff can be used as a basis for billing consumers who are guaranteed a certain forward
temperature. If the “guaranteed” minimum temperature is entered as TL3, the payable consumption is
accumulated in TA3.
EE=15 Return temperature tariff
If the current return temperature (T2) exceeds TL2 but is lower than or equal to TL3, the energy is counted in TA2
parallel to the main register. If the current return temperature exceeds TL3, the energy is counted in TA3 parallel to
the main register.

The return temperature tariff can be used as a basis for weighted user charge. A high return temperature indicates
insufficient heat utilization which is uneconomical for the heat supplier.
