Question 2

"Can I use the product in an area without Internet access?"

Accepted Answer

The water temperature can be managed based on the initial set value (desired water temperature: 26℃ / sensitivity: 0.2℃), so the purpose of basic water temperature management can be achieved, but detailed adjustments of the product (desired water temperature, sensitivity, night mode, Water temperature sensor calibration, etc.) and real-time water temperature check/device abnormal notification functions are not available. Also, since all thermometers have errors (measurement errors), they may differ from the thermometer in use.

Question 3

Can it be used for "120 liter fish tank"?"

Accepted Answer

When installed in a 120 liter (2-character wide) fish tank, “SIZE” can cool more than 4 degrees and heat more than 7 degrees. (compared to non-installed fish tanks)
A larger amount of energy may be required due to heating elements such as lights, filters (sumps), and water pumps. In such cases, it is recommended to install and operate the product additionally.
※Things to check before purchasing
1. Is the glass less than 10mm thick?
2. Have you secured an installation space of 11cm or more around the fish tank?
3. Is the entire front heat exchanger a submersible fish tank?
4. Is it a fish tank with some current?

Question 4

"Register product" failed."

Accepted Answer

Please check the checklist below.
1. Registration may not be possible if the Internet (Wi-Fi) signal of the installation site is weak.
2. Check if the Wi-Fi frequency band of your wireless router is 2.4GHz.
3. If the Wi-Fi name (SSID) contains special characters, it cannot be registered.
4. You cannot register to a wireless router without a password.
5. Reconnect the adapter and try again.

Question 5

I forgot to change the water and left it "connected to the power supply for about 1 minute."

Accepted Answer

The "sheath" prevents excessive temperature rise in the heat exchanger and operates at a maximum temperature of less than 100°C, so it is not as easily damaged as conventional resistance heaters. However, if you leave it in a heated state for a long time, various problems may occur, so special attention is required.
※In the case of cooling, there is no problem even if the heat exchanger is not submerged in water.

Question 6

"I replaced the router" what should I do?"

Accepted Answer

If you replace the router, you must delete the existing product registered in the application and connect it again.
After deleting the device from the application, touch + in the upper right corner to register the device.

Question 7

The "adapter power cable" does not fit well! How do I connect?"

Accepted Answer

When connecting for the first time, turn it slightly and push it all the way in as shown in the picture on the left below.
 
※ For safety, the power connector is designed to fit perfectly.

Question 8

I want to install the product in a "different location"."

Accepted Answer

Moving within the router's signal range is possible without any special action. However, when moving to another location, the device must be initialized and re-registered to be able to control the device with the “Electricua” application.
If you change the name (SSID) and password of the router, you must reset the device and register again.
