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.

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.

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.

Installation manual

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.

ﬁgure1

Pass the temperature sensor cable through the conduit until

it reaches the seal.

Installation manual

Connect the temperature sensor cable to the thermostat as

described in "Wall-mounted installation" on page 6.

NOTE

Install the temperature sensor as close as possible

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.

At the left of the thermostat, gently push the lid.

Remove the front cover by pulling it towards you.

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.

Remove the battery insulator.

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).

Installation manual

Optionally, pass the temperature sensor wiring (EKRTETS)

through the back of the thermostat and wire it as shown

below.

Fasten the thermostat with the supplied screws.

Optionally for the EKRTETS, put the transparent cable

protection back into place and ﬁx the cable protection with

the screw.

Close the thermostat cover.

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.
