Surcharge Quantity Tariff By Means Of Return Temperature (Tariff T8); Volume-Weighted Temperature (Tarif T14) - Landis+Gyr ULTRAHEAT T450 Technical Description

Tariff control (optional)

Surcharge quantity tariff by means of return temperature (tariff T8)

Volume-weighted temperature (Tarif T14)

•
Temperature above "heat threshold" and temperature difference > +0.2 K
→ quantity of heat is acquired
• Temperature below "cold threshold" and temperature difference < -0.2 K →
quantity of cold is acquired
The quantity of energy is summated depending on the temperature cold side
in tariff registers 1 or 2.
The summated quantity of energy is calculated from the difference of the tem-
perature cold side from the defined return temperature threshold (instead of
from the temperature difference).
•
Above return threshold: T1 is summated
•
Below return threshold: T2 is summated
The result of multiplying the volume by the temperature of the warm side is
added to tariff register 1. The result of multiplying the volume by the tempera-
ture of the cold side is added to tariff register 2.
