Xtend Home Tuya smart thermostatic head side display

Xtend Home smart thermostatic head

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

The valve is controlled according to the current ambient temperature and according to the daily schedule you set. Thanks to PID regulation and combination with the daily schedule you will achieve interesting savings in heat consumption. The head is designed for the Tuya Smart application. It also supports third-party applications such as Alexa voice assistant, Google Assistant, SmartThings, Yandex, etc. Remote control takes place via your mobile phone or tablet from anywhere you connect to the internet. You can create time schedules that determine what temperature in the room should be maintained at a given time of day. It works with the Tuya application Scenes and it is possible to control the heating in the room, for example, according to the weather forecast for a given day. Internet outages do not affect the functionality of the head. All settings are stored in the head and it synchronizes with Tuya Smart if necessary.

However, the head also has controls on the body. On its side cover it has LED display with capacitive touch elements. You can easily control the local temperature by touching the illuminated plus and minus symbols. You can also prohibit its manipulation using a child lock and convert the head to a mode where the desired temperature is set only from the application. You install the head by screwing it onto the radiator valve and inserting 2 pcs AA batteries. For operation, it is necessary to have a ZigBee gateway for Tuya. One gateway is enough to operate up to 20 heads. Pairing with a ZigBee gateway is a matter of seconds. For configuration and remote control, you need a mobile phone or tablet with the Android or iOS operating system.

• Radiator head with M30 × 1.5 thread (reduction for M28 × 1.5)
• Display and buttons allowing local control (on the side)
• Display automatically turns off (does not disturb the room)
• Display of the desired and current temperature
• Display of the valve opening degree 0-100%
• Window opening detection function (i.e. suspending heating for a defined period in the event of a sudden drop in ambient temperature)
• Clear display of the operating mode (manual, daily program, holiday)
• Child lock against unwanted changes
• Possibility of correction (calibration) of the measuring sensor
• Division of time periods of the 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 settings for the given time of day
• Power supply from AA batteries, typically lasts for 2 heating seasons
• PID regulation (it is not just valve regulation closed/open), accuracy +/- 1 °C
• Control temperature range from +1 to +70 °C (with a step of 0.5 °C)
• Control setting step 0.5 °C
• Protection against low temperatures (adjustable from 1 to 10 °C)
• Adjustable range of upper and lower temperature limits, preset for the range +5 to +35 °C
• Creation of schemes in the Tuya application - temperature control, reading the room temperature, valve opening status, window opening indication status, etc.
• Requires a ZigBee gateway for remote control, but can also work independently without connecting to remote controls
• We recommend a ZigBee gateway with Tuya support, declaring ZigBee version 3.0 and higher
• Quiet operation of the electric motor during valve position adjustment, automatic calibration to the valve range

The "Descaling" function, i.e. "descaling" or "descaling", which can be enabled or disabled, the default state is enabled. The head performs a full valve movement (opening and closing) at certain intervals. This movement mechanically disrupts any limescale deposits.
