7.2. LED indicators on underfloor heat-
ing controller
The LEDs on the underfloor heating controller indicate the
operating mode of the Underfloor Heating controller and the
installed temperature zones.
Meaning of the 3 LEDs (see fold-out page, Fig. 3 (1,2,3)):
LED Display
POWER (green) Lights up Normal mode
Lights up Group alarm

7.3. Checking the signal strength of the
radio transmission
The signal strength of the radio transmission can be
checked for the transmitter and the receiver. Refer to Sec-
tion "Checking radio transmission
" on Page 11.
7.4. Operating modes of the Underfloor
Heating controller
7.4.1.

Normal mode

In normal mode the LEDs 1...8 show the position of the
actuators, see Fig. 3 (7) on the fold-out page:
Green Thermal drive opened
Off Thermal drive closed
7.4.2.

Fault mode

The various faults are indicated by the zone LEDs in fault
mode. Refer to Section "Displaying faults" on Page 12.
7.4.3.

Installation mode

In installation mode temperature zones are assigned to
the setpoint adjusters and the Hometronic Manager. Re-
fer to Section "Assigning zones and allocating room
names (teach-in)" on Page 9.
7.4.4.

Device display

The device display shows which devices are assigned to
the underfloor heating controller. Refer to Section
"Checking the configuration" on Page 11.
7.5.

Cooling function

If the underfloor heating controller is used as a cooling regu-
lator, this function has to be activated once during installa-
tion.
7.5.1.

Activating the cooling function

► Keep the Mode button pressed for at least 4 seconds.
The shows whether heating or cooling mode is
LED
activated:
LED lights up green Cooling mode active
LED lights up red
► Change the setting by pressing the installation button
Meaning
Antenna fault display
No device installed
Heating mode active

Assigning zones and allocating room names (teach-in)

The underfloor heating controller switches back
to normal mode automatically after 60 seconds.
You can also exit the installation mode by press-
ing the Mode button.
7.5.2. Switching between heating and
cooling
Switching between heating and cooling is carried
out via the changeover contacts 3 and 4.
► In order to activate the cool-
ing function connect the
changeover contacts 3
and 4, (see fold-out page,
Fig. 4 (9)), e.g. through an
external switch.
7.5.3.

Assigning room names

► Enter the room names in the zoning plan.
► Press the installation button
flashes.
The LED of zone 1 flashes red.
► Allocate the setpoint adjuster.
► Press the installation button
The LED of zone 1 flashes green.
► Allocate a time program for Heating.
► Press the installation button
The LED of zone 1 flashes yellow.
► Allocate a time program for Cooling.
Repeat the steps until two room names are assigned to all
the temperature zones.
8. Assigning zones and allocat-
ing room names (teach-in)
The following section explains how you can assign the vari-
ous components to a temperature zone and allocate room
names if a Hometronic Manager is used.
Only one setpoint adjuster can be assigned to a
temperature zone. If a room temperature sensor
HCF 82 is combined with a remote setpoint ad-
juster HCW 82, i.e. assigned to the same zone,
first assign the remote setpoint adjuster and then
the room temperature sensor.
If the installation button
ing controller is not pressed for 4 minutes, the
underfloor heating controller reverts automatically
to normal mode.
8.1. Allocating the setpoint adjuster
HCW 82, room temperature sensor
HCF 82
In the following example the setpoint adjuster HCW 82 is
assigned to Zone 1. Subsequently the room name "Living" is
assigned to Zone 1 in the time program of the Hometronic
Manager.
► Keep the zoning plan at hand.
► Keep the installation button
. controller pressed for 2 seconds.
The LED lights up. The LED of Zone 1 flashes red.
