Smart Thermostat for Combi Boiler/Water Underfloor Heating, WiFi Thermostat Works with Apple HomeKit Siri, Alexa, Google Home, Support Programmer No Hub Required - White - Pack of 1- 240 V
Refoss
Free Shipping
Why we love it
Saves energy with automated heating.
Precise temperature sensing.
Easy remote control operation.
Main Highlights
☀【Smart Thermostat Control】The WiFi heating thermostat is compatible with most boiler/water underfloor heating systems. Note: Smart Thermostats only work with two-wire systems! You can control the heating remotely using the free app “Refoss” or voice control, which is compatible with Apple HomeKit Siri, Amazon Alexa (Echo, Echo Dot), Google Home, or manual touchscreen control. Only 2.4GHz WiFi is supported, and no Hub is required.
☀【Open Window Detection Function】Save energy and reduce electricity bills! When a window is detected as open, the smart thermostat will automatically shut down for 30 minutes to avoid energy waste. The app will also send you notifications to remind you when the window is open.
☀【Dual Temperature Sensor】To accurately sense the room temperature for maximum home comfort, we utilize an internal sensor to detect air temperature and an external sensor wire to measure the floor temperature as needed (installing the external sensor wire is necessary for external sensing). You can switch between the sensors based on different scenarios to better control the heat while preventing overheating. Temperature control range: 5-35°C; Measurement temperature accuracy: 0.1°C.
☀【Schedule and Multi-room Control】You can add and delete scheduling functions, supporting up to 8 events per day. The thermostat allows for a 24/7 schedule for different rooms. Multiple Alexa thermostats can be used to control different rooms. The heating system turns on and adjusts the temperature automatically when you’re at home and turns off automatically when you go out, based on the schedule you set.
❄【Add Summer Mode Function】 The summer mode function can be utilized for cooling during the summer and necessitates a cooling-compatible system, such as an air-to-air heat pump system. Please note that certain features mentioned require the latest version of the app. Ensure that you update both your app and firmware. The iOS version has already been released, and the Android version will be available soon.
