Shows the current actual flow temperature.
Displays the current pressure in the heating circuit.
Displays values for the energy consumption for the following time
periods: Today, Yesterday, Last month, Last year, Total.
The display shows an estimation of the values for the installation.
The values are influenced by the following, for example: Installa-

vironmental conditions, tolerances and components.
External components, such as external heating pumps or valves,
and other consumers and appliances in the household are still not
taken into consideration.
