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.

The below procedure only serves as an example.

NOTE

Your actual situation may differ from what is
represented here.

1

Ta ke the installation suggestions for the thermostat into
account when selecting the installation location.

Refer to figure 3.

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.

Connect the temperature sensor cable to the thermostat as
described in "Wall-mounted installation" on page 6.

Install the temperature sensor as close as possible

NOTE

to the floor loop inlet and as close as possible to the
floor surface as shown in the figure on page 4.

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).

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.

Be careful not to pinch the wiring when fastening.

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.
