EKRTETS Room thermostat Installation manual
Read this manual attentively before starting up the unit.
Do not throw it away. Keep it in your files for future
reference.
Improper installation or attachment of equipment or
accessories could result in electric shock, short-circuit,
leaks, fire or other damage to the equipment. Be sure
only to use accessories made by Daikin which are
specifically designed for the use with the equipment and
have them installed by a professional.
If unsure of installation procedures or use, always
contact your dealer for advice and information.

EKRTR + EKRTETS
Room thermostat

1. Introduction
The room thermostat EKRTR can be used to control the Daikin
system (radiator heating and floor heating/cooling applications).
It is typically connected to the Daikin unit. Refer to the "Typical
application examples" in the Installation manual of the Daikin
unit.
■ In case of floor heating-only applications the room
thermostat can also be connected to the individual motorized
valve of the floor heating loop.
■ If a floor heating-only application is used in combination with
fan coil units each fan coil unit should have its dedicated fan
coil thermostat.
Optionally, an external temperature sensor EKRTETS can be
connected to the thermostat and used as:
■ external ambient temperature sensor to control the room
temperature (instead of the temperature sensor inside the
thermostat). In that case, install the temperature sensor
where you want to control the ambient temperature.
■ floor temperature sensor (only for floor heating/cooling
applications) to protect the floor temperature or to prevent
dew on the floor (in case of floor cooling). In that case, install
the temperature sensor in the floor (refer to "Installation of
EKRTETS as floor temperature sensor (only for floor
heating/cooling applications)" on page 3).
In case of extreme or sudden changes in weather
conditions, despite the dew prevention function,
condensation on the floor could occur.
To avoid reoccurrence, we suggest changing the
field settings (refer to "Set-up floor temperature
protection and dew prevention function (only for
floor heating/cooling applications)" on page 15.
In case the conditions are so extreme that this
countermeasure is not adequate, we suggest not
to use floor cooling.

2. Installation of EKRTETS as floor
temperature sensor (only for floor heating/
cooling applications)
As it should be integrated into the floor, the installation of the
temperature sensor EKRTETS should be planned and
performed in advance.
If EKRTETS is installed as floor temperature sensor, the
thermostat EKRTR should be wall-mounted. Refer to "Wall-
mounted installation" on page 6.
1 Take the installation suggestions for the thermostat into
account when selecting the installation location.
Refer to figure 3.
NOTE
The below procedure only serves as an example.
Your actual situation may differ from what is
represented here.

2 Integrate the EKRTETS temperature sensor in an electrical
conduit ( ∅ 16 mm maximum) in the floor construction as
shown below.
Make sure to seal the temperature sensor electrical conduit
to protect the thermostat from hot air currents and to allow
the replacement of the temperature sensor.

3 Pass the temperature sensor cable through the conduit until
it reaches the seal.

3. Installation of the EKRTR
You can mount the EKRTR thermostat on the wall or use it as
table-top model.
3.1. Wall-mounted installation
The EKRTR thermostat can be wall-mounted, with supplied
screws and plugs. Refer to figure 1.
This is the case when you want to install the optional EKRTETS
as external temperature sensor.
1 At the left of the thermostat, gently push the lid.
2 Remove the front cover by pulling it towards you.
3 Optionally for the EKRTETS, unscrew the screw of the cable
holder in the bottom left corner of the back part of the
thermostat and remove the transparent cable protection.
4 Remove the battery insulator.
5 Drill holes in the wall taking the dimensions of the thermostat
into account and insert the supplied plugs in the holes.
Refer to figure 4 (unit of measurement: mm).

6 Optionally, pass the temperature sensor wiring (EKRTETS)
through the back of the thermostat and wire it as shown
below.
7 Fasten the thermostat with the supplied screws.
8 Optionally for the EKRTETS, put the transparent cable
protection back into place and fix the cable protection with
the screw.
9 Close the thermostat cover.
10 Remove the protective film from the LCD.
3.2. Table-top installation of the thermostat
Only if the optional temperature sensor
EKRTETS is not installed as external
temperature sensor, the EKRTR can be
used as a table-top model.
In that case, no particular installation
for the thermostat is needed. The
thermostat functions as a complete
wireless unit and can be put anywhere
in the house into its table holder.
Remove the battery insulator and the protective film from the
LCD, as described in "Wall-mounted installation" on page 6.
Be careful not to pinch the wiring when fastening.

3.3. Installation of the receiver
The receiver needs to be installed indoors, typically close to the
unit.
Recommendations for an optimum signal
reception
Take the installation suggestions for the receiver into account
when selecting the installation location and follow the
recommendations below.
■ Do not install the receiver inside a metal box.
■ Mount the receiver vertically, and minimum 10 cm away
from the unit.
■ Mount the receiver minimum 10 cm away from any vertical
metal pipe or vertical electric circuit.
■ Mount the receiver at least 1.5 m above the ground.
Before obtaining access to terminals, all power
supply circuits must be interrupted.

5 According your application, perform the wiring.
5a When connected to the unit, refer to the wiring diagram of
the unit.
For heating-only applications, wire connection to C is not to
be installed.
Use wire size 0.75~1.50 mm
2
.
5b When connected to the motorized valve, wire the motorized
valve and the receiver as shown below (for heating-only
applications).
The output relays (H and C are voltage-free contacts) can
handle a maximum load of 4 A - 230 VAC.
All field wiring and components must be installed by
a licensed electrician and must comply with relevant
European and national regulations.

Receiver-thermostat radio configuration
You need to configure the radio connection between the receiver
and the thermostat in order to make communication possible.
1 Put the receiver in radio configuration mode by pressing
è
during 4 seconds.
The
!
LED lights up green and the receiver is now waiting for
a thermostat configuration address.
If needed, you can simply exit this mode by pressing
è
again.
2 Send the configuration address by going to code 5® 03 ( ®ƒ ‡≈î‹ )
in the installer menu on the thermostat.
Refer to “Setting up codes in the installer menu” on page 14.
The thermostat will now send radio signals. On the LCD the
icon
j
flashes.
3 Verify that the radio signals are correctly received by the
receiver.
If the configuration is OK, the
!
LED blinks green at each
radio signal received from the thermostat.
This also means that the receiver has left the radio
configuration mode.
4 On the thermostat, exit the installer menu by pressing
>
till
the "
/
" code is displayed and then pressing
=
.
5 Verify if the receiver is in thermostat mode and not in manual
mode by checking if the
è LED is off.
Refer to "LED overview" on page 12.
Make sure to protect the power supply with a fuse of
3 A (X2M).
Select the power cable in accordance with relevant
local and national regulations.
A main switch or other means for disconnection,
having a contact separation in all poles, must be
incorporated in the fixed wiring in accordance with
relevant local and national legislation.

used to manage and thus protect the floor temperature. Refer to
"Installation of EKRTETS as floor temperature sensor (only for
floor heating/cooling applications)" on page 3. When this function
is active the icon
U flashes below the ambient temperature.
In cooling mode, the dew prevention function will make sure
there will be no condensation on the floor. The dew point is
calculated based on room temperature and room humidity.
When the floor temperature drops below the dew point the
cooling demand will be temporarily stopped and the icon
