2 Turn on multiple set point 1: [7-03]=0
Turn on multiple set point 2: [7-04]=0
3 Enter the temperature multiple set point 1: [A-03] (see below)
Enter the temperature multiple set point 2: [A-04] (see below)
Configuration example:

Space 1 45°C [A-03]
Space 2 35°C [A-04]
Resulting heat pump water
Pattern B can also be used to do some primary multi zoning (if all set
point temperatures are selected the same, no temperature reducing
device ( ) is required).
Multiple thermo ON signals for 3 rooms can be generated. Thermo
OFF signals are only valid if all requests are OFF.
NOTE Leaving water control is not allowed for pattern B.
It is the installers responsibility to make sure no
unwanted situations can occur (e.g. too high
water temperatures towards floor heating loops,
etc.).
It is the installers responsibility to make sure the
water circuit is well balanced (e.g. when a
domestic hot water request occurs, there will be
sufficient flow towards other appliances as well,
etc.)
Daikin does not offer any temperature reducing
device (
possibility to use multiple set points.
When space 0 is in thermo OFF, but space 1 or 2
are active, space 0 will be fed with water at a
temperature equal to the highest set point of
spaces 1 and 2.
This can lead to unwanted heating of space 0.
