10.3. TYPE OF SENSOR

The controller has a built-in sensor but is is also possible to use an additional wireless sensor. Such a sensor must be
registered using one of the options: <Wireless sensor> or <Registration>. Next, press the communication button on the
sensor within 30 seconds. If the registration process has been successful, the controller will display a message to confirm.
If an additional sensor has been registered, the main display will show information about WiFi signal and battery level.
NOTE
If the battery is flat or there is no communication between the sensor and the controller, the controller will use
the built-in sensor.

10.4. SENSOR CALIBRATION

Sensor calibration should be performed during installation or after a longer period of using the regulator when the room
temperature (room sensor) or external temperature (external sensor) measured by the sensor is different from actual
temperature. Range of regulation is -10 to +10 ⁰C with the accuracy of 0,1°C.
