IMMAX NEO LITE Nexa Smart for electric underfloor heating 16A, Zigbee
The IMMAX NEO LITE Nexa Smart thermostat with Zigbee for 16A electric underfloor heating regulates the temperature in electric underfloor heating systems. The device operates on the Zigbee 3.0 wireless protocol with a frequency of 2,400MHz to 2,483.5MHz and communicates with mobile apps for remote setup. A mechanical rotary knob changes the set temperature values directly on the wall without a touch screen. The device measures temperatures in a range of +5°C to 99°C in 0.5°C increments and switches an operating load of up to 16A. The 80 × 80 × 60mm unit has an IP20 rating and a mains standby power of 1.5W.
Key Features of the IMMAX NEO LITE Nexa Smart Thermostat for 16A Electric Underfloor Heating, Zigbee

- The colour TFT display shows the current weather, outdoor temperature, and air humidity
- Adjustable screen backlighting offers the option to turn it off completely during the night
- An external NTC temperature sensor with a 3m length accurately measures the floor temperature
- Weekly scheduling offers modes with six time changes during the day
Thermostat Integration
The device connects to smart home systems via the Zigbee 3.0 communication protocol. It requires a central hub to operate, which facilitates the connection with other elements of the network. The IMMAX NEO PRO or TUYA Smart Life mobile apps provide remote control and temperature changes from anywhere. This allows users to monitor the current heating status even when away from home.
Display and Data Visualisation
The device has a colour TFT display that shows the current room temperature and time. The screen also displays additional information such as the current weather, outdoor temperature, and air humidity. The screen backlighting can be adjusted by the user or turned off completely for undisturbed night-time operation. The display brightness thus adapts to the light conditions in the room.
Scheduling Options
The device supports weekly and daily schedules for energy saving. Users can set 5 + 2, 6 + 1, or 7-day modes with different temperatures. Each day includes up to six separate time slots for precise operational customisation. The programme mode changes the temperature according to the set schedule without the need for manual intervention.
External Temperature Sensor
The package includes an external NTC temperature sensor with a 3m cable length. This sensor measures the temperature directly in the floor and prevents it from overheating. The floor sensor has parameters of B = 3380 and R25 = 10kΩ +/- 1%. The thermostat evaluates data from both the internal and external sensors to regulate the heating. The measurement accuracy shows deviations of +/- 1°C in the range of +5°C to 99°C. The temperature correction is +/- 9°C with an adjustable hysteresis in the range of 1 to 5°C.
Wireless Connection
The wireless signal has a range of 30m in open spaces and 5m in built-up interiors. The device also functions as a signal repeater in the Zigbee network. The integrated repeater extends the range for other smart devices throughout the home. Data transmission occurs on a frequency of 2,400MHz to 2,483.5MHz with a high RF output power in the range of 10–19dBm. The system operates with a supply voltage of AC 100–230V, and the mains standby power is 1.5W.
Voice Control and Compatibility
The device supports integration with Amazon Alexa, Google Assistant, and Siri voice assistants. The temperature in the house can be changed with voice commands. The mobile app supports iOS and Android operating systems for compatibility with phones. The settings and accompanying app are available in Czech, Slovak, English, German, Hungarian, and Polish. The system works with Apple Siri shortcuts, Tuya, Smartlife, Lidl Home, and TESLA Smart platforms.
