5 Operating and display functions
–
You can use this function to set the desired set-back
temperature for the zone.
Set-back temp. heat. is the temperature that you want to
have in the rooms during the night or when you are away
from home (night mode).
Menu → Information → System status → Room temperat-
ure
–
If the controller is installed outside of the heat generator,
you can read the current room temperature.
The controller has an integrated temperature sensor, which
determines the room temperature.
5.1.1.3 Ventilation
Menu → Information → System status → Air quality
sensor 1/2
–
You can use this function to read the measured values
from the air quality sensor.
Menu → Information → System status → Exhaust air hu-
midity
–
You can use this function to read the exhaust air humidity
in the ventilation unit's ventilation shaft.
5.1.2 Display of energy consumption and energy
yield
In the display and in the app that can also be used, the con-
trol displays values for the energy consumption and/or the
energy yield.
The control displays an estimation of the values for the in-
stallation. Among other things, the values are influenced by
the following:
–
The installation/design of the heating installation
–
User behaviour
–
Seasonal environmental conditions
–
Tolerances and components
External components, such as external heating pumps or
valves, and other consumers and appliances in the house-
hold are still not taken into consideration.
The deviations between the energy consumption or energy
yield that is displayed and the actual energy consumption or
energy yield may be significant.
The specifications for the energy consumption or energy
yield are not suitable to be used to create or compare energy
billing.
5.1.2.1 Consumption
Some components do not support the calculation of con-
sumption, the total of which is shown on the display. In the
instructions for the components, you can find out if and how
the individual components determine the consumption.
Menu → Information → Consumption → Current month →
Heating → Electricity
–
You can use this function to read the total electrical con-
sumption for heating in the current month.
Menu → Information → Consumption → Current month →
Heating → Fuel
–
You can use this function to read the total fuel consump-
tion in kWh for heating in the current month.

tion in kWh for hot water since start-up.
5.1.2.2 Diagram: Reading the solar yield
Menu → Information → Solar yield
–
The diagram under Solar yield shows a comparison of
the monthly solar yields between the previous and the
current year.
The total yield is displayed on the bottom right. The highest
value achieved in one month for the last two years is dis-
played in the top right.
