Configuration Wizard: Additional Zone; Detailed Screen With Weather-Dependent Curve - Daikin Altherma 3 R F Installation Manual

5 Configuration
# Code
[2.4] N/A Setpoint mode:
▪ Fixed
▪ WD heating, fixed cooling
▪ Weather dependent
When weather dependent operation is active, low outdoor
temperatures will result in warmer water and vice versa. During
weather dependent operation, the user can shift the water
temperature up or down by a maximum of 10°C.
Schedule
Indicates if the desired leaving water temperature is according to a
schedule. Influence of the LWT setpoint mode [2.4] is as follows:
▪ In Fixed LWT setpoint mode, the scheduled actions consist of
desired leaving water temperatures, either preset or custom.
▪ In Weather dependent LWT setpoint mode, the scheduled
actions consist of desired shift actions, either preset or custom.

5.2.7 Detailed screen with weather-dependent
curve
When weather-dependent (WD) operation is active the desired
leaving water or tank temperature is determined automatically
depending on the averaged outdoor temperature. When the outdoor
temperature is lower the leaving water or tank temperature will need
to be higher as the water pipes will be colder and vice versa.
Slope and offset
Define the weather-dependent curve by its slope and offset:
▪ Change the slope to differently increase or decrease the
temperature of the leaving
temperatures. For example, if leaving water temperature is in
general fine but at low ambient temperatures too cold, raise the
slope so that leaving water temperature is heated increasingly
more at decreasingly lower ambient temperatures.
▪ Change the offset to equally increase or decrease the
temperature of the leaving
temperatures. For example, if leaving water temperature is always
a bit too cold at different ambient temperatures, shift the offset up
to equally increase the leaving water temperature for all ambient
temperatures.
