5.9.4 Using weather-dependent curves
Configure weather-dependent curves as following:
To define the setpoint mode
To use the weather-dependent curve, you need to define the correct
setpoint mode:
Go to setpoint mode … Set the setpoint mode to …
Main zone – Heating
[2.4] EN20190625 > Setpoint
mode
WD heating, fixed cooling
OR Weather dependent
Main zone – Cooling
[2.4] EN20190625 > Setpoint
mode
Weather dependent
Additional zone – Heating
[3.4] Additional zone >
Setpoint mode
WD heating, fixed cooling
OR Weather dependent
Additional zone – Cooling
[3.4] Additional zone >
Setpoint mode
Weather dependent
Tank
[5.B] Tank > Setpoint mode Restriction: Only available to
installers.
Weather dependent
To change the type of weather-dependent curve
To change the type for all zones (main + additional) and for the tank,
go to [2.E]
EN20190625 > WD curve type .
Viewing which type is selected is also possible via:
▪ [3.C]
Additional zone
>
WD curve type
▪ [5.E] Tank > WD curve type
Restriction: Only available to installers.

Zone Go to …
Main zone – Heating [2.5] EN20190625 > Heating WD
curve
Main zone – Cooling [2.6] EN20190625 > Cooling WD
curve
Additional zone – Heating [3.5] Additional zone >
Heating WD curve
Additional zone – Cooling [3.6] Additional zone >
Cooling WD curve
Tank Restriction: Only available to
installers.
[5.C] Tank > WD curve
INFORMATION
Maximum and minimum setpoints
You cannot configure the curve with temperatures that are
higher or lower than the set maximum and minimum
setpoints for that zone or for the tank. When the maximum
or minimum setpoint is reached, the curve flattens out.
To fine-tune the weather-dependent curve: slope-offset curve
The following table describes how to fine-tune the weather-
dependent curve of a zone or tank:

offset:

6 Energy saving tips
Tips about room temperature
▪ Make sure the desired room temperature is NEVER too high (in
heating mode) or too low (in cooling mode), but ALWAYS
according to your actual needs. Each saved degree can save up
to 6% of heating/cooling costs.
▪ Do NOT increase/decrease the desired room temperature to
speed up space heating/cooling. The space will NOT heat up/cool
down faster.
▪ When your system layout contains slow heat emitters (example:
underfloor heating), avoid large fluctuation of the desired room
temperature and do NOT let the room temperature drop too low/
rise too high. It will take more time and energy to heat up/cool
down the room again.
▪ Use a weekly schedule for your normal space heating or cooling
needs. If necessary, you can easily deviate from the schedule:
▪ For shorter periods: You can overrule the scheduled room
temperature until the next scheduled action. Example: When
you have a party, or when you are leaving for a couple of hours.
▪ For longer periods: You can use the holiday mode.
Tips about DHW temperature
▪ Make sure the desired DHW temperature, reflected by storage
tank temperature, is NOT too high. Example: After installation,
lower the tank temperature daily by 1°C and check if you still have
enough hot water.
