the heating installation.
Menu →Information →System status →System status
–You can use this function to read the heating installa-
tion's operating mode.
–Standby: The heating installation has no energy require-
ment and is in standby.

Menu →Information →System status →Collector temp
–You can use this function to read the current temperature
on the collector temperature sensor.
Menu →Information →System status →Solar yield
–You can use this function to read the total solar yield.
Menu →Information →System status →Reset solar yield
–If you select the setting Yes under the Reset solar yield
function and press the right-hand selection button OK,
you reset the previously totalled solar yield to 0 kWh.
Menu →Information →System status →Environment
yield
–You can use this function to read the total environment
yield.
Menu →Information →System status →Reset environ-
ment yield
–If you select the setting Yes under the function Reset en-
vironment yield and press the right-hand selection but-
ton OK, you reset the previously totalled environmental
yield to 0 kWh.
Menu →Information →System status →Curr. room air
humidity
–You can use this function to read the current room air
humidity. The room air humidity sensor is installed in the
controller.
Menu →Information →System status →Current dew
point
–You can use this function to read the current dew point.
The dew point indicates the temperature at which the
water vapour in the air condenses and settles on objects.
Menu →Information →System status →triVAI
–You can use this function to read whether the heat pump
or the auxiliary heater (gas, oil or electricity) is currently
covering the energy requirement. The energy manager
uses the triVAI and the comfort criteria to decide which
heat generator to use.
If the value that is read is greater than 1, the heat pump is
better at covering the energy requirement than the auxiliary
boiler.
5.1.1.2 ZONE1
Menu →Information →System status →Day temp. heat-
ing
–You can use this function to set the desired day temper-
ature for the zone.
Day temp. heating is the temperature that you want in the
rooms during the day or when you are at home (Comfort
mode).
Menu →Information →System status →Day temp. cool-
ing
–You can use this function to set the desired day temper-
ature for the zone.

rooms during the day or when you are at home (Comfort
mode).
Menu →Information →System status →Set-back temp.
heat.
–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 in
the rooms during the night or when you are away from home
(Set-back 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 1/2/3
–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 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
