SATEL ART-200 5
Radio communication
The thermostat connects to the controller at regular time intervals to provide information
about its state (periodical communication). Additional communication takes place when the
ART-200 thermostat is sending to the controller the settings adjusted manually.
Energy saving mode (ECO)
If you want to prolong the battery life, you can enable the “ECO” option in the device. When
the “ECO” option is enabled, the periodical communication takes place every 3 minutes.
This will prolong the battery life.
Battery status control
When the battery voltage is below 2.3 V, information about low battery will be sent during
each transmission and the symbol will be flashing on the display. When the voltage drops
below 2.1 V, the thermostat will disable the valve control in order to protect the battery from
complete discharge. The message F03 will be displayed and the valve will be 25% open.
Operating modes
Comfort temperature –thermostat is to maintain room temperature at a comfortable level.
This mode can be enabled remotely or manually.
Economy temperature –thermostat is to maintain room temperature at an energy-efficient
level (e.g. when household members are at work or asleep at night). This mode can be
enabled remotely or manually.
Manual setting of the valve position / temperature –radiator valve is set in a given
position / thermostat is to maintain the set temperature. This mode can be enabled
remotely or manually but the valve position / temperature can only be set manually.
The “Manual setting of the valve position / temperature” can be enabled remotely if the
controller is connected to a SATEL alarm control panel. If the operating mode has
been enabled remotely, the thermostat can only be controlled manually. Remote
control is possible only after the mode is disabled remotely.
Thermostat calibration
When calibrating, the thermostat adjusts its actuator stroke to the radiator valve stroke.
During calibration, the thermostat operating range is defined (the valve end positions, where:
0% = valve fully closed, 100% = valve fully open). The thermostat must be calibrated after it
is installed on the valve and each time after batteries are replaced. The CAL message will be
displayed when calibration is required.
Thermostat adaptation
After it is started, the thermostat will find the optimal valve position to reach and maintain the
set temperature in the room. When the valve is open insufficiently, the room takes too long to
heat up. When the valve is open too much, the room heats up fast but the temperature
continues to rise beyond the set value and the room is too hot. The adaptation is repeated
whenever the thermostat detects that the conditions in the room have changed in a way that
can affect its operation. When the adaptation is in progress, the ADPT message and the
temperature will be displayed alternately.
You can disable the adaptation function (see: “Edit the advanced settings” p. 11). When this
function is disabled, the temperature will be regulated using the thermostat manufacturer
settings.

6 ART-200 SATEL
Boost Heat
If the room temperature is too low and uncomfortable, you can enable the Boost Heat
function to heat the room faster. The valve will then be fully open for a set time (by default: 15
minutes). The remaining time of the Boost Heat function will be displayed.
You can turn off the function yourself (see: “Keys” p. 4). If you do, the preset operating mode
will be enabled.
The Boost Heat function has the highest priority. When it is enabled, other functions
and settings are ignored.
Anti-scale protection
Scale can build up inside the valve when it remains unused for a long time. To prevent it,
the thermostat will fully open the valve once every two weeks.
Open window detection
The thermostat can detect a sudden drop in temperature, e.g. caused by open window.
The radiator valve will then be closed for a set time (by default: 30 minutes) or until the
thermostat detects a rise in temperature. The symbol will be flashing when the valve is
closed as a result of open window detection.
You can restore the thermostat to the normal operating mode manually (see: “Edit the
advanced settings” p. 11).
Anti-freeze protection
When temperature drops below 5°C, the thermostat will open the valve to prevent the
radiator from freezing. The valve will remain open until the thermostat operating mode is
changed or temperature rises to 8°C. When the anti-freeze protection is activated, the A-FR
message will be displayed alternately with temperature registered by the sensor (labelled as
). When the protection is activated, this information is sent to the controller during
periodical communication.
Temperature measurement correction
The thermostat can correct the temperature information provided by the internal sensor.
The correction can be made in the range of ±3,5°C.
Child lock
You can disable the thermostat keys to prevent the settings from being accidentally changed
(e.g. by children at play). The keys can be disabled manually or remotely. You cannot enable
the keys manually if they have been disabled remotely. The LOC message will be displayed
for 20 seconds after disabling the keys and each time any key is pressed. If you enable the
keys, information about the currently selected operating mode will be displayed.
3 Installation
There is a danger of battery explosion when using a different battery than
recommended by the manufacturer, or handling the battery improperly. Do not
crush the battery, cut it or expose it to high temperatures (throw it into the fire,
put it in the oven, etc.).
Do not expose the battery to very low pressure due to the risk of battery
explosion or leakage of flammable liquid or gas.

SATEL ART-200 7
Be particularly careful during installation and replacement of the battery.
The manufacturer is not liable for the consequences of incorrect installation of
the battery.
The used batteries must not be discarded, but should be disposed of in
accordance with the existing rules for environment protection.
The device is designed for indoor installation. When in use, the ART-200 thermostat must be
located within the radio range of the ABAX 2 controller. Thick walls, metal partitions, etc. will
reduce the range of the radio signal. Use the ARF-200 tester to check the level of radio
signal. Place the tester close to the valve on which you want to install the thermostat. If the
radio signal level indicated by the tester is higher than 40%, you can install the thermostat
there.
The thermostat is fitted for radiator valves with the M30 x 1.5 mm threaded connection. It is
compatible with most radiator valves on the market. In order to install the thermostat on the
Danfoss RA valve, use the supplied adapter.
You do not need any special tools to install the thermostat. Disconnecting the heating
system is not required.
1. Use your fingers to press down the symbols on both sides of the battery cover (gray
element on Fig. 4). Pull to remove the cover.
2. Install two 1,5 V LR6 AA alkaline batteries (they are not supplied with the thermostat).
When the batteries are installed, the CAL message will be displayed. The actuator rod will
be completely withheld inside the thermostat cover so that it is possible to install the
thermostat on the valve.
3. Add the thermostat to the wireless system (see the ABAX 2 controller manual). For that,
you need the thermostat serial number. You will find it on a sticker inside the battery
cover.
4. Replace the battery cover.
5. Install the thermostat on the valve (see: “Installation on M30x1.5 mm valve” or “Installation
on Danfoss RA valve”). If the actuator rod (labelled as on Fig. 7) is not completely
withheld inside the thermostat cover, remove the batteries before installation, insert them
back and wait until the rod hides inside the cover.
Before you remove the old thermostatic head, make sure to turn it several times from
minimum to maximum position and back. Unscrew the old thermostat when it is in the
maximum position. When the thermostat is removed, the valve pin should be fully
extended.
