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.
