V. External temperature sensor
ST-292v2 room regulator may optionally be equipped with an external temperature sensor. The
sensor should be mounted in a shaded place so that it is not affected by the weather conditions.
The current temperature value will be sent to the room regulator every few minutes and it will be
displayed on the main screen.
The external sensor communicates with the room regulator via radio signal. Both the room
regulator and the external sensor are pre-configured to operate on channel “35”, but the user
may easily change the channel (if the current channel is used by other devices).
How to change communication channel:
In order to change the channel, press and hold the channel change button. After the control light
on the sensor flashes, the process of channel change has been initiated. Hold the button and wait
until the light starts flashing again. The number of flashes corresponds to the first digit of the
desired channel number.
Release the button after the desired number of flashes and press it again to set the second digit
of the channel number – the control light flashes quickly twice. Hold the button and wait until the
light flashes the desired number of times. When the button is released, the control light flashes
twice – the new communication channel has been set.
NOTE: In case of a one-digit channel number (channels 0÷9) set 0 as the first digit.
Example 1:
28 is the desired communication channel. In order to select this channel, set the first digit - 2,
and the second digit – 8.
Press and hold the channel change button - the control light flashes quickly once - the process of
channel change has been initiated. Hold the button and wait until the light flashes two more times
(the first digit of the channel number – 28).
Release the button and press it again – the control light flashes quickly twice – the process of
setting the second digit has been initiated. Hold the button and wait until the light flashes 8 times.
When the button is released, the control light flashes quickly twice – the new communication
channel has been successfully set.
Example 2:
7 is the desired communication channel. In order to select this channel, set the first digit - 0, and
the second digit – 7.
Press and hold the channel change button - the control light flashes quickly once - the process of
channel change has been initiated. As the first digit is 0, release the button before the control
light flashes again. Press the button again – the control light flashes quickly twice – the process
of setting the second digit has been initiated. Hold the button and wait until the light flashes 7
times (the second digit of the desired number). When the button is released, the control light
flashes quickly twice – the new communication channel has been successfully set.
In case of errors in the channel change process, the control light goes on for ca. 2 seconds. In
such a case the channel will not be changed.
