About this item
- IMPORTANT: FOR DRY-CONTACT BOILERS ONLY - Your system must have: 1) A boiler with dry-contact (on/off) control terminals, and 2) Standard 220V wiring (Neutral N and Phase L wires) available at the thermostat location. This thermostat connects to your boiler via two passive (non-voltage) wires on ports NO and COM, acting as a simple on/off switch (Max. 5A). It does not work with two-wire or battery-powered thermostat systems.
- Control from Anywhere - Effortlessly connect your KETOTEK Boiler Thermostat WiFi to home network for seamless remote control via Smart Life/Tuya APP. You can monitor and adjust your room temperature, create schedule and use a variety of options in the App from anywhere, anytime. Share access with family for collaborative control. 2.4GHz WiFi required (don't support 5GHz).
- Alexa/Google Assistant Compatible - This WiFi Thermostat for Boiler works with Alexa and Google Assistant. Connecting to Alexa is as easy as setting up any other Alexa skill. Once connected to Alexa, you can set your home temperature or turn on/off the thermostat by voice, without getting out from under the covers, especially in the winter.
- Energy-Saving Automation - Choose Program, Manual, or Holiday mode to match your routine. Program mode offers 5-2 (weekday and weekend), 6-1 (Sunday different from the rest) and 7-0 (all days the same) weekly schedules with 6 time/temperature settings per day. With smart window detection, the Smart Boiler Thermostat pauses heating if sudden temperature drops (like an open window) occur, saving energy and money.
- More Reliable Features - Offering a 5℃~35℃ temperature range, this smart thermostat for boiler offers reliable features you'll love: heating/cooling mode selection, temperature history query, standby backlight setting, temperature calibration, reset function and memory function, etc. If you don't want others to change settings through the wall display, you can lock the thermostat.
- Easy Installation - Not flush-mounted design. This thermostat WiFi is easily wall-mounted with screws, or installed on a standard 86 mm x 86 mm back box, Ø60 mm round back box, or 503 back box. Power Supply Connection: Connect the N wire and L wire to supply power to the thermostat. Boiler Control Connection: Use two dry-contact wires (no voltage) to connect to the boiler for start/stop control. Power supply: AC 90-240V 50/60Hz, Output: Max 5A.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
