Xtend Home Tuya smart set Zigbee gateway + 2x thermostatic heads with display on the side

Xtend Home set 2× thermostatic heads + unit

Starter pack for smart regulation of residential radiators. Contains 2 smart thermostatic heads and one Zigbee gateway. The package is expanded with a description of how to use the heads in the Tuya system.

The heads control the radiator valves 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 and gateway are designed for the Tuya Smart application.

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 the given day. Internet outages do not affect the functionality of the head. All settings are stored in the head and, if necessary, it is synchronized with Tuya Smart. However, the head also has controls on the body. On its side cover, it has an 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 switch 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.

The Zigbee gateway wirelessly connects the thermostatic heads and your Wi-Fi router. It is universally usable for any device supporting the Tuya Smart system. Simply place the Zigbee gateway anywhere within range of the Wi-Fi access point (AP) or router, and within the radio range of the controlled heads and any other Tuya devices. The gateway in the package is enough to operate at least 20 heads. Pairing with the Zigbee gateway is a matter of seconds. Further expansion of the system is easy by purchasing additional thermostatic heads and other Tuya elements. For configuration and remote control, a mobile phone or tablet with Android or iOS operating system is required.

• 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
• Range of control temperatures 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 temperature in the room, valve opening status, window opening indication status, etc.
• Silent operation of the electric motor during valve position adjustment, automatic calibration to the valve range

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