MULTIBETON Symondo Digital Room Thermostats Sensor
Product Information
The Symondo Sensor is a digital room thermostat designed for surface heating and cooling systems. It is equipped with a built-in multi-sensor and digital communication via a 1-Wire bus in conjunction with a current version of the Symondo Box. The sensor features intuitive operation via integrated touch areas and LEDs, and it is capable of monitoring air quality via colored status LED. The device has a power supply of 5V DC ( +/- 10 %) and power consumption of 0.6 W. It has an IP20 protection class and dimensions of 80 mm x 80 mm. The sensor housing is made of plastic pure white, and it is designed for surface /flush-mounted installation.

Product Usage Instructions Symondo Sensor
Wall Mounting and Electrical Connection
- Select a suitable location for the sensor, avoiding direct sunlight, sources of heat and cold.
- Attach the mounting frame (2) to the switch box.
- Make the electrical connection by connecting the sensor to a 5V DC power supply. GND = Grey, DQ= Orange, VCC= Red.
- Insert the element by holding the cover frame (1 – not included in the scope of delivery) against the mounting frame (2).
- Press the Symondo Sensor (3) with the mounting frame until it engages in the frame.
- Each sensor has a unique 1-Wire ID required for sensor room assignment in the Symondo Box. You will find the ID on the small sticker supplied.
Mounting on plastic wall socket
Attach the mounting frame (2) to the switch box. Make the electrical
connection as described below.
Electrical connection

Hold the cover frame (1 – not included in the scope of delivery) against the
mounting frame (2). Symondo Sensor (3) with the mounting frame and press it in
until it engages in the frame.
Operation
Standby Screen
IAQ ok
Touching the touch areas activates “Display”.
Measuring unit and measured value display
The first touch of the touch area shows the temperature. Repeated touching
changes to other measured values and first shows the unit and after a short
time the measured value. 
Setpoint adjustment
The set temperature can be reduced or increased by touching the blue and red
touch areas.
The Symondo Sensor has an intuitive operation via integrated touch areas and LEDs. The first touch of the touch area shows the temperature. Repeated touching changes to other measured values and first shows the unit and after a short time the measured value. The set temperature can be reduced or increased by touching the blue and red touch areas. There are two ways to assign the Symondo Sensor to a room:
- Using the 1-Wire ID via the Symondo Controller menu ‘Expert -> Settings -> Room’.
- By Touch-To-Assign function (T2A) via the Symondo Controller menu and on the Symondo Sensor.
To assign the sensor:
- Go to Expert > Settings > Rooms on the Symondo Controller menu.
- Select or add a room and select sensor type Temp./Humidity.
- Touch the Symondo Sensor on one of the three touch areas to assign it to the selected room.
LED
In the first few days after installation, the Symondo Sensor goes through a
calibration phase during which fluctuating measurements and major deviations
may occur.
Set room setpoint
- Activate the room setpoint menu (1) by touching the touch area (1). Reduce (2) or raise (3) the room setpoint by touching the touch areas.
After 20 seconds, the display returns to the standby screen.
The set room setpoint is valid until the next change via Symondo Controller timer or manually.
Symondo Sensor with Symondo Box
The 1-Wire system must be realized with 3 wires (5VDC, DQ, GND). The total cable length can be up to 100m. Use a suitable twisted pair cable and ensure sufficient wire cross-section, e.g. with LIYCY 2 x 2 x 0.75mm², to avoid impermissible voltage drop at the Symondo Sensor below U min = 4.5VDC.
