FAQs for Aqara Radiator Thermostat E1

What types of valves are supported for the installation of the thermostat?
The size of nuts of the thermostat is [M30*1.5mm], and the accessories include: adaptors for the three types of valves (RA, RAV, RAVL), please refer to the operation manual for the installation method.

What precautions should be taken for the installation of the thermostat and the calibration of the valve?
Every time after the thermostat is powered on, the installation state will be activated ([F11] interface), and it is suggested that the thermostat should be installed on the valve within 5 minutes, after the installation is complete, press the key three times successively to carry out valve calibration, or proceed with networking in accordance with the operation manual, and then carry out valve calibration after the networking is complete.

*Reminder: if installation is not complete within 10 min after power-on, please first remove the battery, then put the battery back, and power on for installation.

What is valve calibration?
Because the push rods of different valves have different strokes, it is necessary to carry out calibration of the valve before installation, so that the open/close stroke of the valve can be adaptable, which is an important step to make sure of correct temperature control. After power-on, it is suggested that the thermostat should be installed on the valve within 5 min. You may press the key three times successively to carry out the valve calibration, or do the same with the Aqara Home app.

After the battery is put in place, why is the thermostat not reacting?
Possible causes:

A. The battery is reversed, so please reinstall the battery (note: wait 30 sec before reinstalling the battery, after the battery is removed).
B. Battery power is low. Please replace the battery.
C. Product failure. Please contact the vendor for repair or replacement of the product.
*Reminder: if the thermostat automatically shuts down, it may be caused by low battery power. In that case, it is suggested that the battery should be replaced.

How to place a networked temperature sensor?
When networked, the Aqara Temperature & Humidity Sensor should be placed in the same room with the thermostat, 2-3 meters away from the thermostat, but it should not be placed too close to windows.

*Reminder: the Aqara Temperature & Humidity Sensor is supported only if it is networked under the same hub.

What is Anti-freeze mode?
In case of prolonged travel in winter (e.g. tourism or business trip), the anti-freeze mode can be enabled to avoid freezing of water pipes due to low temperature, in which case low-temperature operation will be active.

What is Manual mode?
Once a temperature value is manually set, the thermostat will regulate and keep the temperature with reference to the set temperature. For instance, under the manual mode, if the Smart Schedule is enabled, the temperature regulation will be performed in accordance with the temperature regulation plan of the Smart Schedule.

What is the function of the built-in temperature sensor?
The thermostat has a built-in temperature sensor, which is used to detect the temperature around the radiator and provide auxiliary temperature control. You can also use the Connect the Temperature Sensor function with the Aqara Home app to network with the Aqara Temperature & Humidity Sensor, to get a better temperature control experience.

What is "Window-open detection"?
When the indoor temperature plunges in a short time, the system will remind the user that it may be resulted from the opening of doors or windows, and will simultaneously close the valve for 30 min to avoid energy waste. You can also set up networking with the Aqara Door and Window Sensor through the Automation function, in order to get a more precise experience of window-open detection.

How long will the battery last?
The sustainability of the battery depends on the user's temperature regulation frequency and the power-on/power-off frequency of the thermostat. In winter, it is suggested that you should not frequently power on and off the thermostat, to reduce the use frequency of the motor. In the summer season, when heating is suspended, it is suggested that you should power off the thermostat to reduce the loss of the battery's power capacity.
