Programmable with smartphone. Suitable for all room controller variants. Room controller temperature setting range 5-35 °C. Floor controller temperature setting range 5-50 °C. With display. 10 A, 230 V AC.
With the programmable room thermostat featuring a display, you can regulate room and/or floor temperature. The thermostat has connection options for conventional actuators in hot water heating systems (radiators, underfloor heating, etc.) or electric underfloor heating. The user-friendly thermostat learns through the optimum start function how long the heating takes to reach the desired comfort temperature. With the help of a weekly and/or holiday program, the room temperature can be reduced during absences to save energy costs. To ensure that the apartment is cozy and warm again upon return, the thermostat switches the heating on in good time (optimum start).
The thermostat displays the current temperature and recognizes various operating modes with individual temperature set points: comfort mode, ECO mode (night operation), weekly program, holiday program, and frost protection. Thanks to the optimum start function, it learns how long the heating needs to reach the desired temperature and can initiate the warming process in time.
The programmable thermostat is backward compatible with conventional Feller thermostats (exception: 4250 only in heating mode, without 4250-24) and features a real-time clock as well as automatic summer and winter time adjustment. For temperature reduction, you can connect an external switch or timer to the thermostat. The internal switching of operating modes is overridden in this case.

Energy Savings: When the Aqara Smart Radiator Thermostat E1 is connected to the Aqara Door and Window Sensor or the Aqara Motion Sensor, it will turn off the heating when it detects that a door or window is open or if no movement has been detected for a certain period. Additionally, schedules can be set for desired time periods such as day or night. It can automatically open or close the radiator valve, helping to reduce your energy consumption.
Geofencing and Support for Multiple Apartments: No more entering a cold apartment. When you set up geofencing, the Radiator Thermostat E1 will start heating the apartment before your arrival. If you own more than one apartment, you can set up automations for each of these apartments independently.
