USE, CLEANING AND MAINTENANCE
Press the keys with your fingers. The use of sharp objects may cause damage to
the device.
To clean the display use a soft, slightly damp and lint-free cloth, without using
excessive force.
Attention: the keys are active only if the device is hooked to the base
Switch off
Normal operation
Note: in heating mode (winter), if the Thalos RF is off, it regulates the antifreeze
Toff
temperature in order to prevent freezing of the system.
Toff
can have values from 1 to 10° C or be excluded; in this case any minimum
temperature is guaranteed.
Replace the batteries as soon as
possible! Dispose of the
batteries in the appropriate

In this case the Thalos RF activates the receiver for 10
minutes every 4 hours (if the antifreeze temperature

active)
Occurs for the following values of measured tempera-
ture:
t < 0°C
t >50°C
Unhook and re-hook the thermostat from the base. Press the keys for at least 3 seconds during the flashing.
The advanced programming menu is divided into two parts: programming of operating parameters (
PR
) and test of the radiofrequency transmission (
RF
).
To access it, press simultaneously the keys and for at least 3 seconds until

appears. At this point choose which menu to access with the keys or .
You will enter the selected menu after 3 seconds without pressing any key.

THALOS RF
Thalos RF is an electronic touch screen thermostat to regulate the ambient
temperature both in heating and in cooling to control a remote actuator through
radiofrequency signal.
Powered by two batteries of AAA type, Thalos Rf doesn’t need any wiring.
This allows to install the thermostat anywhere inside your room, without any
intervention of masonry.
The wide touch screen display with backlighting on by pressing a key allows a
clear view even in the dark.

SAFETY WARNINGS
During product installation and operation it is necessary to observe the
following instructions:
1) The device must be installed by a qualified person, in strict compliance with the
connection diagrams.
2) Do not power the device if any part of it is damaged
3) The device must be installed and activated in compliance with current electric
system standards
4) Do not use the device for purposes different from the one specified.
5) In case of malfunction do not perform repairs and contact immediately the
technical support.
6) The device can be used in environments with category of measurement III and
pollution degree 2.
TECHNICAL CHARACTERISTICS
• Power supply: 2 alkaline batteries from 1.5V ( AAA type)
• Battery life: about 1 year
• Wall-mounting installation or to cover the 503 box
• Summer (cooling) / winter (heating) / off (with antifreeze) operating mode
• Regulation type:
- on/off with settable differential (0.1 ÷ 1°C)
- P8 proportional with 0.8°C band (-0.3 ÷ +0.5°C) and period 8 minutes
- P15 proportional with 1.5°C band (-0.7 ÷ +0.8°C) and period 15 minutes
- tP proportional by opening modulation (only if associated with valves for
radiators)
• Measurement precision: ±0.5°C
• Measurement temperature resolution: 0.1°C
• Settable setpoint range: 2°C ÷ 35°C
• Operating temperature: 0°C ÷ +50°C
• Storage temperature: -10°C ÷ +65°C
• Operating humidity: 10% ÷ 90% non condensing
• Touch screen display with backlighting on with a key touch
• Password protected lock keypad
• Communication with the actuator through a radiofrequency signal 433.92 MHz
• Maximum distance between thermostat and actuator: 50 m in free field
• Protection degree: IP40
• Association between Thalos RF and remote actuator
Because the Thalos RF and a remote actuator can communicate correctly, it’s
necessary to perform a procedure called “self-learning”, during which the remote
actuator recognizes and stores the identity of Thalos RF.
To perform the self-learning proceed as follows:
1. Activate the channel configuration of the remote actuator (see the
instructions). The actuator remains in configuration mode for a pre-set time,
within which it must receive the configuration string from Thalos RF.
2. Insert the batteries in the Thalos RF, respecting the polarity indicated on the
device (to access the batteries compartment it’s
necessary to unhook the thermostat from the base
by pressing the tab at the bottom of the device).
After about 3 seconds the Thalos RF initiates the
configuration procedure (indicated by
[NF
on the
display) followed by a short test procedure (indicated
by
TST
on the display) where Thalos RF sends the
sequence on-off-on-off to the actuator.
3. Upon receipt of the configuration string, the remote actuator is configured
and resumes the normal operation while the Thalos RF displays the ambient
temperature (the programming keys will be active only after you have hooked
the thermostat at the base).
• Indications for placement
The Thalos RF is designed for wall-mounting installation or to cover the 503 box.

2
Fix the base on the wall
using the screws supplied.
Attach the thermostat to the base, at first
mating teeth first placed on the upper side.
Place the thermostat at a height at about 1.5 m above the floor, away
from direct sunlight, away from doors, windows, heat sources, locations
with excess or total lack of aeration.
The actuator is usually placed near the boiler to pilot.
Attention: the maximum distance between Thalos RF and remote actuator is about
50 m in free field. This value is reduced if there are obstacles in the middle (for
example, reinforced concrete walls).
During normal operation the Thalos RF displays the value of the measured temperature and the possible activation command to the remote actuator is indicated by the
symbol
(heating mode) or by the symbol
(cooling mode).

= (to be used only if associated with valves for radiators) allows the valve
to work by opening modulation, i.e. it opens in proportional way to the
difference between the setpoint and the measured temperature
Differential -
d0.3
- (only for on/off regulation)
Differential (or hysteresis) for temperature regulation
Settable values: 0.1 ÷ 1°C
Password for keypad lock -

to disable the lock.
If the keypad lock is active, pressing one key
LoC
appears and
the password is required. If it’s properly inserted the keyboard
is unlocked for the next 30 seconds.
Note: if you do not press any key within 10
seconds the instrument exits the menu
showing
END
.
Test -
tSt
The test is used to verify the correct
communication between Thalos RF and
the actuator and it can last 10 minutes
the maximum. To activate the test,
press the key for at least 3 seconds
until
TST
will stop flashing. During the
test the commands of on and off are
sent to the actuator every 10 seconds.
To stop the test, press the key for at
least 3 seconds.
Note: to associate a second remote actuator, activate the configuration of the actuator
channel and, while this last is in configuration mode, remove the thermostat from the
base and re-put it (the thermostat starts the configuration procedure to which follows
the testing procedure).
