Xtend Home Thermostatic head/ radiator/ Zigbee/ Tuya/ side display/ white

The smart thermostatic head is used to automatically control the radiator valve.

It controls the valve according to the current ambient temperature and according to the daily schedule you set. Thanks to the PID control and the combination with the daily schedule , you will achieve interesting savings in heat consumption.

The head is designed for the Tuya Smart app. It also supports third party apps such as Alexa voice assistant, Google Assistant, SmartThings, Yandex etc.

Remote control is done via your mobile phone or tablet from anywhere you connect to the internet. You can create schedules that determine what room temperature to maintain at a given time of day. It works with Tuya's Scenes app, so you can control the heating in a room according to the weather forecast for the day, for example. Internet outages do not affect the functionality of the head. All settings are stored in the head and the head synchronises with Tuya Smart if necessary.

However, the head also has controls on the body. It has an LED display with capacitive touch elements on its side cover. You can easily control the local temperature by touching the illuminated plus and minus symbols. Likewise, you can disable its manipulation by using the child lock and thus convert the head to a mode where the desired temperature is set only from the app.

You install the head by screwing it onto the radiator valve and inserting 2 AA batteries. A ZigBee gateway for Tuya is required for operation. One gateway is enough to operate up to 20 heads. Pairing with the ZigBee gateway is a matter of seconds.

A mobile phone or tablet with Android or iOS is required for configuration and remote control.

• Heads for M30 × 1.5 thread radiator (reduction for M28 × 1.5)


• Display and buttons allowing also local control (on the side)


• Display automatically switches off (does not disturb the room)


• Display of desired and current temperature


• Display of valve opening degree 0-100 %


• Window opening detection function (i.e. heating is suspended for a defined period of time when the ambient temperature drops suddenly)


• Clear display of the operating mode (manual, day program, holiday)


• Child lock against unwanted change


• Possibility of correction (calibration) of the measuring sensor


• Division of time of day, division of the week into working (5+2 or 6+1) or full week mode (7-day mode), 6 time sections per day, automatic temperature control according to the setting for the time of day


• Powered by AA batteries, typically lasts 2 heating seasons


• PID control (not just closed/open valve control), accuracy +/- 1 °C


• Control temperature range from +1 to +70 °C (in 0.5 °C steps)


• 0.5 °C control step


• Low temperature protection (adjustable from 1 to 10 °C)


• Adjustable upper and lower temperature limit range, preset for +5 to +35 °C range


• Creation of schematics in Tuya - temperature control, room temperature reading, valve open status, window open indication status, etc.


• Requires a ZigBee gateway for remote control, but can also work standalone without remote control connection


• ZigBee gateway with Tuya support, declaring ZigBee version 3.0 and higher is recommended


• Quiet operation of electric motor during valve position adjustment, automatic calibration to valve range

Function "Descaling" i.e. "descaling" or "descaling", which can be enabled or disabled, default state is enabled.

The head performs full valve movement (opening and closing) at certain intervals. This movement mechanically disturbs any scale deposits.
