5.7 Setting up an external temperature
sensor
Indoor ambient temperature
You can connect one external temperature sensor. It can measure
the indoor ambient temperature. Daikin recommends to use an
external temperature sensor in the following cases:
▪ 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
▪ If this is NOT possible, Daikin recommends to connect a remote
indoor sensor (option KRCS01-1).
▪ Setup: For installation instructions, see the installation manual of
the remote indoor sensor.
▪ Configuration: Select room sensor [A.2.2.B].
Outdoor ambient temperature
The remote outdoor sensor (delivered as accessory) measures the
outdoor ambient temperature.
▪ Setup:
▪ To install the remote outdoor sensor outside, see the
installation manual of the sensor (delivered as accessory).
▪ To connect the remote outdoor sensor to the indoor unit, see
"7.6.7 To connect the remote outdoor sensor" on
▪ Configuration: None.

Preparing 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 the installation location with sufficient place for carrying the
unit in and out of the site.
6.2.1 Installation site requirements of the
indoor unit
INFORMATION
Also read the precautions and requirements in the
"General safety precautions" chapter.
▪ Mind the following spacing installation guidelines:
≥50 ≥50
(mm)
Do NOT install the unit in places such as:
▪ In places where a mineral oil mist, spray or vapour may be
present in the atmosphere. Plastic parts may deteriorate and fall
off or cause water leakage.
▪ Sound sensitive areas (e.g. near a bedroom and the like), so that
the operation noise will cause no trouble.
▪ The foundation must be strong enough to bear the weight of the
unit. Take the weight of the unit with a domestic hot water tank full
of water into account.
Make sure, in the event of a water leak, water cannot cause any
damage to the installation space and surroundings.
▪ In places with high humidity (max. RH=85%), for example a
bathroom.
▪ In places where frost is possible. Ambient temperature around the
indoor unit should be >5°C.
▪ The indoor unit is designed for indoor installation only and for
ambient temperatures ranging from 5~30°C.

Preparing piping

6.3.1

Circuit requirements

INFORMATION
Also read the precautions and requirements in the
"General safety precautions" chapter.
Circuit types. Except for the refrigerant circuit, inside the unit 2
other circuits are included. For future references: the circuit
connected to the bore hole is referred to as the brine circuit, the
other circuit connected to the heating emitters is referred to as the
space heating circuit.
▪ Connecting piping – Legislation. Make all piping connections in
accordance with the applicable legislation and the instructions in
the "Installation" chapter, respecting the water inlet and outlet.
