Radiator Thermostat E1

FAQ

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 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 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 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 the function of the Smart Schedule?

You may set the smart temperature control plan for a day, and activate the plan, then the thermostat will automatically regulate the temperature according to the plan. If the temperature in a certain time frame of the original plan becomes inappropriate due to abrupt weather changes (e.g. sudden rise in outdoor temperature), you may not need to shut down the smart schedule, but can manually regulate the temperature of the current time frame, without creating an impact on the temperature planning of the subsequent time frame, to cope with the sudden changes of weather conditions more flexibly.

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.

Why does the Aqara Home app prompt for temperature control abnormality and the LCD screen displays the fault icon?

You can enable/disable the Valve Detection function on the settings page. In order to prevent the prolonged low-temperature or high-temperature state of room temperature from becoming uncomfortable, the thermostat will remind the user of temperature control abnormality when it detects that the room temperature can't reach the set temperature, after heating is started, for the following possible causes:
A. The thermostat is not installed correctly. It is suggested that you should remove the battery and put it back 30 sec later, then reinstall the thermostat and calibrate it again, and further wait for a period of time, and then observe whether the fault is eliminated.
B. The room temperature is significantly higher than the set temperature due to the incorrect temperature setting. It is suggested that you should re-set the temperature again, wait for a period of time, and then observe whether the fault is eliminated.
C. Valve failure. Please replace the valve, reinstall the thermostat, and carry out valve calibration.
D. The room is too large (the radiator is not matching) or there is too much ventilation in the room. It is suggested that you should replace the radiator or test whether the room door or window is opened or leaking air.
E. The inlet water pressure or inlet water temperature is too low. Please check the inlet water pressure and inlet water temperature.
F. Upon networking with the temperature sensors, no linkage is established with the temperature sensor in the same room, or the distance from the temperature sensor to the radiator is remote (it is recommended that the temperature sensor should be placed in the same room with the thermostat, for a distance of 2-3m from the thermostat).

Why, when the thermostat operates correctly, is the room temperature is obviously higher than the set temperature?

Possible causes:
A. The thermostat is not correctly installed. Remove the valve from the thermostat, withdraw the battery and wait for 30 sec, then put the battery back, and reinstall the thermostat, and carry out valve calibration when the device's screen displays the [F11] installation interface (you can press the key three times successively to carry out valve calibration, or do the same with the Aqara Home app).
B. Valve failure. After replacing the malfunctioning valve, reinstall the valve and carry out valve calibration according to the above step.

Why, when the thermostat seems to operate normally, is the room temperature is obviously lower than the set temperature?

Possible causes:
A. Valve failure. After replacing the valve, withdraw the battery and wait for 30 sec, then put the battery back, and reinstall the thermostat, and carry out valve calibration.
B. The water inlet temperature of the radiator is low. Please contact professional technicians to overhaul the hot-water pipeline.

Why can't the thermostat can't be operated through the Aqara Home app?

Possible causes:
A. The thermostat is not networked with the Aqara Home app. Please carry out re-networking.
B. The thermostat is too far from the hub, or there are multiple barriers in between. Please adjust the distance, or provide more hubs.
C. Battery power is low. Please replace the battery.

Why, when the thermostat seems to operate normally, does the room temperature not remain constant?

Possible causes:
A. Battery power is low. Please replace the battery.
B. Too much ventilation in the room, which results in excessive heat loss. Please check whether the room door or window is opened or leaking air.
C. Check the installation position of the networked temperature sensor, and verify whether the networked temperature sensor is remote from the thermostat (greater than the range of 2-3 m) or placed too close to any ventilation spot (such as a door or window).

Why is the Aqara Home app prompting linkage abnormality?

Possible causes:
A. The networked device (temperature sensor) is offline, malfunctioning, or abnormally networked, etc. Please check the networked device, or carry out re-networking.

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.

What is the function of creating a device group?

You can organize multiple thermostats in a room into a group to realize collective temperature regulation, power-on/off, mode switching, and create automation. This function only supports device control, and doesn't support device status synchronization.
