The output relays (H and C are voltage-free contacts) can handle a
maximum load of 5 A — 230 V. For heating only application, wire
connection C is not to be installed.
WARNING
Protect the power supply with a fuse of 0.065 A (X2M) and
select a power cable that is in accordance with applicable
legislation.
WARNING
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 applicable legislation.

Put the cable bracket back in place and tighten the screws.
8
Put the receiver cover back in place and tighten the screws.
INFORMATION
To fully complete the installation of the receiver, configure
the radio connection between the receiver and the room
thermostat.
See
NOTICE
To ensure access, keep the front of the receiver clear at all
times.
6.3
To install the external temperature
sensor as floor temperature sensor
As it should be integrated into the floor, the installation of EKRTETS
should be planned and performed in advance. When EKRTETS is
installed as a floor temperature sensor, the room thermostat must be
mounted to the wall. See
"6.1 To install the room thermostat"
3] for
more information.
INFORMATION
The following procedure only serves as an example. Your
actual situation may differ from what is represented here.
Prerequisite:
You have considered the site requirements for the
room thermostat when selecting the installation location. See
"5.1 Installation site requirements"
3] for more information.

Integrate the temperature sensor in an electrical conduit
(Ø16 mm maximum) in the floor construction.

Pass the temperature sensor cable through the conduit until it
reaches the seal.
3
Connect the temperature sensor wiring to the room thermostat
as described in
"6.1 To install the room thermostat"
4
On the room thermostat, set the value for parameter 20 (rEGU)
to FLR in the installer menu. For more information about the
installer menu, see
6].
NOTICE
Properly seal the temperature sensor electrical conduit in
order to protect the room thermostat from hot air currents
and to allow for possible future replacement of the
temperature sensor.

(b)
If enabled, this function will activate the installation in advance
(up to a maximum of 2 hours) to ensure that the desired setpoint
is reached at the appropriate time according to the set program.
With every program change, the room thermostat measures the
time taken by the installation to reach the setpoint to compensate
for any temperature differences that may be present at different
times. This allows you to make program changes without needing
to adjust the temperature in advance, because the room
thermostat does this automatically.
