Available versions of the device:
NXW299.4 Temperature Sensor Module TUKAN (flush-mounted)
NXW299.5 Temperature Sensor Module TUKAN (hermetic)
An element of the Nexo system responsible for temperature measurement. It is most commonly used for coordinating the operation of heating, air conditioning, ventilation, and controlling other devices with a temperature-dependent operating parameter in the range of -30/110 degrees Celsius.
KEY PRODUCT FEATURES:
The small housing makes it very easy to install the sensor in a junction box. The rectangular housing allows the sensor to be placed among numerous wires without difficulty when mounting under a traditional switch.
The indicator LED informs whether the device has received the correct bus status and if communication with the system is proceeding correctly.
The miniature probe allows for easy and discreet installation of the sensor under a switch or in another location designated for temperature measurement.

Window connectors ensure 100% quality of the bus wiring installation.
Easy bus addressing – The appropriately recessed switch allows easy code setting of the address. Its placement and design prevent accidental address switching during installation along with the wires.
● Module adapted for installation in an electrical junction box under a switch or socket
● Precise temperature sensor placed on an additional measurement wire
● Sensor with a long measurement wire (optional when ordering)
● NTC thermistor enabling extension of the probe with the sensor
● Sensor in a hermetic version for embedding in the floor (optional when ordering)
● Temperature correction function
● Heating inertia hysteresis function
● 7 programmable thermostats
● Bus communication (bus wires output from the device)

TWO SENSOR VERSIONS TO CHOOSE FROM
The product is available in two versions.
- With a miniature probe, which allows easy and discreet installation of the sensor under a switch or in another location designated for temperature measurement
- With a hermetic probe, which allows temperature measurement in outdoor conditions and in a floor screed for underfloor heating purposes.
Colors you love…
DIVE INTO THE COLORS OF THE RAINBOW
The pool lighting can take on a color depending on the temperature. The warmer the water, the warmer the color, or perhaps you’d prefer the opposite?


THE WARMTH OF THE HOME FIRESIDE
Nexo, through control of electrovalves in heating loops based on temperature sensor readings placed in various parts of the house, ensures that the temperature in the rooms is maintained at the desired level.
When dealing with a floor structure sensitive to elevated temperatures, it is reasonable to use a hermetic temperature sensor embedded in the floor. This will stop the heating at the right moment, thus protecting the floor from deformation.
YOU NEED TO KNOW THIS
You’re spending your winter break with your family abroad, and the temperature in the house is rapidly dropping? A heater malfunction during a cold spell should not be ignored. Nexo will notify you via SMS to take the necessary action.


A Slippery Situation…
Winter is a time when injuries are easy to come by. The anti-icing system can often save you from spraining an ankle, but its proper operation is essential. The temperature sensor’s indication will ensure its correct functioning, eliminating the risk of an unfortunate accident.
