-
Radio frequency (RF) thermostat (868
MHz) specially designed for water floor
heating systems. Each thermostat pos-
sesses with an own personal code. Thus
a clear allocation to the receiver is en-
sured.
-
Equipped with a LCD display to select
Comfort (
), Night reduction (
) or Off
mode.
-
Temperature indication for desired value
and actual value (room temperature)
-
This thermostat can be used only with the
1 channel receiver or with the radio re-
ceiver (TIMER) of the manufacturer.
START UP
Use the switch on the right side of the ther-
mostat to power on or power off the heating.
Be careful! In mode OFF, your installation can
freeze.
The setting temperatures are kept in memory
indefinitely.

RADIO CONFIGURATION MODE
-
Position that/ those radio room thermostat/s in the proximity of the radio
Receiver (TIMER or 1 channel receiver)
-
For the allocation of the RF thermostat to a receiver, you must put the receiver in “RF init”
mode (please refer to the receiver leaflet).
-
After you just h
ave to press “
Ok
” key during 5 sec. If the display ( “rF “)
is indicated, the thermostat sends its configuration address by radio signal.
-
When the receiver is configured, press “
Ok
” key to return to user menu. The desired
room temperature can be adjusted.
Use
“
Ok
” key to change the mode in the
Operating mode menu
COMFORT operating mode:
Force comfort temperature operation indefi-
nitely. By pr/- keys the comfort tem-
perature starts to blink and can be adjusted.
The measured temperature reappears
after a few seconds.
REDUCTION operating mode:
Force reduced temperature operation indefi-
nitely. By pr/- keys the comfort tem-
perature starts to blink and can be adjusted.
The measured temperature reappears after
a few seconds.
DISPLAY
Press the (
OK)
key during 5 seconds. The display switches at first in the radio initialization mode "rF".
Then use
+
or
-
keys to select and adjust the installation parameter. Press
OK
to toggle the parameter setting or edit the value. If the
value starts to blink you can use
+
/
-
keys to adjust this value. Once you have adjusted the value press
OK
to validate
this parameter value.
When you have finished, use
+
or
-
keys to go to ‘rF’ display and then press
OK
key to exit installa-
tion parameter menu. Without an input, the display switches after 30 seconds in the normal operation mode. The
changed parameters thereby are saved. Press + & - keys at the same time to reset this value to the factory default value.
