NOVASTAT RF DIGITAL (RT-RFD)
USER GUIDE
MODES DESCRIPTION
-
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 have 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.
Switch on and switch off the thermostat
Use "Ok" key to change the mode in the
Operating mode menu
COMFORT operating mode:
Force comfort temperature operation indefi-
nitely. By pressing +/- 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 pressing +/- keys the comfort tem-
perature starts to blink and can be adjusted.
The measured
temperature reappears after
a few seconds.

INSTALLATION PARAMETERS MENUS
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.
