Preferential kWh rate power supply

General rule
▪ Power meter 1: Measures the refrigerant part of the outdoor unit.
▪ Power meter 2: Measures the rest (i.e. the hydro part of the
outdoor unit, control box
EK2CB07CAV3, the backup heater kit, and the optional booster
heater).
Setup
▪ Connect power meter 1 to X2M/7 and X2M/8 of option box
EK2CB07CAV3.
▪ Connect power meter 2 to X2M/9 and X2M/10 of option box
EK2CB07CAV3.
Power meter types
▪ Power meter 1: Single-phase or three-phase power meter.
▪ Power meter 2: Single-phase power meter.

5.5 Setting up an external temperature
sensor
You can connect one external temperature sensor. It can measure
the indoor or outdoor ambient temperature. Daikin recommends to
use an external temperature sensor in the following cases:
Indoor ambient temperature
▪ In room thermostat control, the user interface is used as room
thermostat and it measures the indoor ambient temperature.
Therefore, the user interface must be installed on a location:
▪ Where the average temperature in the room can be detected
▪ That is NOT exposed to direct sunlight
▪ That is NOT near a heat source
▪ That is NOT affected by outside air or air draught because of,
for example, door opening/closing

box
▪ For installation instructions, see the installation manual of the
remote indoor sensor and the addendum book for optional
equipment.
Configuration: Select room sensor [A.2.2.F.5].
Outdoor ambient temperature
▪ In the outdoor unit, the outdoor ambient temperature is measured.
Therefore, the outdoor unit must be installed on a location:
▪ At the north side of the house or at the side of the house where
the most heat emitters are located
▪ That is NOT exposed to direct sunlight
▪ If this is NOT possible, Daikin recommends to connect a remote
outdoor sensor (option EKRSCA1).
▪ Setup: For installation instructions, see the installation manual of
the remote outdoor sensor and the addendum book for optional
equipment.
▪ Configuration: Select outdoor sensor [A.2.2.B].
▪ If the desired leaving water temperature is weather dependent, the
full time outdoor temperature measurement is important. This is
another reason to install the optional outdoor ambient temperature
sensor.
INFORMATION
The external outdoor ambient sensor data (either averaged
or instantaneous) is used in the weather-dependent control
curves and in the automatic heating/cooling changeover
logic. To protect the outdoor unit, the internal sensor of the
outdoor unit is always used.

Preparation

6.1

Overview: Preparation

This chapter describes what you have to do and know before going
on-site.
It contains information about:

▪ Preparing the installation site

▪ Preparing the water piping
▪ Preparing the electrical wiring
6.2 Preparing the installation site
Do NOT install the unit in places often used as work place. In case
of construction works (e.g. grinding works) where a lot of dust is
created, the unit MUST be covered.
Choose an installation location with sufficient space for carrying the
unit in and out of the site.
6.2.1 Installation site requirements of the
outdoor unit
INFORMATION
Also read the precautions and requirements in the
"General safety precautions" chapter.
Mind the following spacing guidelines (see "Service space: Outdoor
unit" in the chapter "Technical data").
