Preferential power supply contact (on the domestic hot
water tank)
INFORMATION
For the exact position of connectors X6Y, X6YA, and X6YB
in the switch box, see the service manual.
INFORMATION
In case of preferential kWh rate power supply, the
necessity of a separate normal kWh rate power supply to
the hydro part of the outdoor unit X3M/5+6 depends on the
type of preferential kWh rate power supply.
A separate connection to the hydro part of the outdoor unit
is required:
▪ if preferential kWh rate power supply is interrupted
when active, OR
▪ if no power consumption by the hydro part of the
outdoor unit is allowed at the preferential kWh rate
power supply when active.

INFORMATION
Shut-off valve usage example.
In case of one LWT zone,
and a combination of underfloor heating and heat pump
convectors, install a shut-off valve before the underfloor
heating to prevent condensation on the floor during cooling
operation. For more information, see the installer reference
guide.

Commissioning
NOTICE
General
commissioning
checklist.
Next
to
the
commissioning instructions in this chapter, a general
commissioning checklist is also available on the Daikin
Business Portal (authentication required).
The general commissioning checklist is complementary to
the instructions in this chapter and can be used as a
guideline and reporting template during the commissioning
and hand-over to the user.
7.1
Overview: Commissioning
This chapter describes what you have to do and know to
commission the system after it is installed and configured.
Typical workflow
Commissioning typically consists of the following stages:
1
Checking the "Checklist before commissioning".
2
Performing an air purge.
3
Performing a test run for the system.
4
If necessary, performing a test run for one or more actuators.
5
If necessary, performing an underfloor heating screed dryout.
7.2
Precautions when commissioning
INFORMATION
During the first running period of the unit, the required
power may be higher than stated on the nameplate of the
unit. This phenomenon is caused by the compressor, that
needs a continuous run time of 50 hours before reaching
smooth operation and stable power consumption.
