Dear Customer,
NOVATEK-ELECTRO thanks you for purchasing our product.
After carefully studying this Operating Manual, you will be able to use the product correctly. Keep this Operating Manual throughout the entire service life of the product.
The multifunctional timer relay EM-126T (hereinafter referred to as the product or EM-126T) is a microprocessor device designed for home automation — a smart plug.
EM-126T allows you to turn on/off loads according to a schedule or manually, while simultaneously protecting the load from various voltage emergencies and power overloads.
EM-126T includes a temperature sensor (for measuring air temperature), which allows the product to control heating or cooling equipment depending on the measured air temperature value.
EM-126T is equipped with one control button (for entering Wi-Fi setup mode or manual load control) with two indicators (for displaying emergencies, load status, and Wi-Fi network connection status).
After registration on the “my.overvis.com” server, control and configuration of EM-126T is possible from anywhere in the world with an internet connection.
EM-126T accumulates energy consumption statistics in real time and sends the accumulated data to the “my.overvis.com” server, allowing you to view saved reports for a week, month, or year.
You can save electricity and reduce your costs by using EM-126T to control heating and ventilation equipment according to a pre-planned schedule.
Based on energy consumption statistics, the “my.overvis.com” server can suggest the most optimal schedule settings.
EM-126T connects to the user-specified access point, performs measurements and monitors mains parameters (voltage and current) to protect the load, as well as maintains temperature according to the user-defined schedule.
In case of an emergency (current or voltage value exceeding the set level, voltage dropping below the set level, temperature sensor malfunction), the product performs emergency load disconnection.
If the user manually changed the load state from the front panel or remotely via the “my.overvis.com” server, EM-126T blocks the execution of the current scheduled event and switches to manual control mode.
After the next scheduled event occurs, EM-126T returns to normal operation mode.
The manual control state is remembered even after the product is disconnected from the mains.
In Wi-Fi connection setup mode, EM-126T creates its own access point named “EM-126T_xxxxxxxx”, where xxxxxxxx is the unique product code.
The user, by connecting to this access point and using a web browser (Opera, Google Chrome, Firefox, etc.) to navigate to “http://192.168.4.1”, gains access to the product’s Wi-Fi connection settings.
To enter the setup mode, press and hold the “ENTER” button (Fig. 1, pos. 1) on the front panel of the product for 5-6 seconds. The “ENTER” button will start flashing blue-red and EM-126T will create an access point named “EM-126T_xxxxxxxx”, where xxxxxxxx is the unique product code.
Using an electronic device (PC with Wi-Fi, phone, tablet, laptop, etc.), connect to the access point using the following parameters:
Access point name: “EM-126T_xxxxxxxx”
Security: None
Launch a web browser (Google Chrome, Opera, Firefox, etc.) on the electronic device.
After successful authorization, the status page loads, displaying current information about the EM-126T state. All information is read-only.
At the top of the screen, the device name “overvis EM-126T”, current temperature “23.3°C”, and the ”☰” button for opening the main menu are displayed.
In the middle of the screen, there is a manual control button and readings of measured mains parameters (load current and power, mains voltage and frequency).
At the bottom of the screen, there are counters of consumed electricity and the amount of money spent.
Configuration and control via the “my.overvis.com” server is only possible after configuring the Wi-Fi connection and completing authorization on the “my.overvis.com” server (see “Wi-Fi Connection Setup”).
On an electronic device (PC, laptop, mobile phone, tablet, etc.), enter the link “http://my.overvis.com/smartplug” in the web browser address bar (Google Chrome, Opera, Firefox, etc.) and navigate to it.
The screen of the device from which the navigation was performed will display connection options for EM-126T. Select the most appropriate option and follow the further instructions displayed on the screen.
After connecting to EM-126T, configure the necessary parameters following the on-screen instructions.
To disconnect from EM-126T — simply close the “my.overvis.com” page.
The load operation logic (on/off) depends on the specified load type (“Load type” parameter).
If “Load type” is set to “Heater”, the load will turn on when the temperature reaches a value equal to “Temperature setpoint” minus 3°C “Temperature hysteresis”, and the load will turn off when the temperature reaches a value equal to “Temperature setpoint”.
If “Load type” is set to “Cooler”, the load will turn on when the temperature reaches a value equal to “Temperature setpoint” plus 3°C “Temperature hysteresis”, and the load will turn off when the temperature reaches a value equal to “Temperature setpoint”.
After the load is turned on, EM-126T constantly monitors the mains voltage, current, and power consumed by the load. If one of them exceeds the set thresholds, EM-126T performs emergency load disconnection.
Also, after EM-126T is plugged into the mains socket, it connects to the user’s Wi-Fi network (for time synchronization and access to the “my.overvis.com” server).
After receiving a manual control command (from the front panel or the “my.overvis.com” server), the current scheduled event execution is blocked, the load is turned off (or turned on depending on the command), and EM-126T switches to manual control mode.
After the next scheduled event occurs, manual control is disabled and EM-126T returns to normal operation mode.
Every 1-2 hours (depending on the “my.overvis.com” server load), accumulated statistics are sent to the “my.overvis.com” server.
During operation, EM-126T constantly measures the mains voltage value.
In case of a sudden voltage increase above 300±10 V, load disconnection will occur with a minimum time delay of 0.02 s (fixed time).
In case of a gradual voltage increase above the 255 V threshold (Upper disconnect threshold), the load will be disconnected after 0.5 s (Upper threshold disconnect delay).
After load disconnection, if the mains voltage decreases below 250 V (“Upper disconnect threshold” minus “Hysteresis”), return to normal operation mode will occur after the AR time.
In case of voltage decrease below the 190 V threshold (Lower disconnect threshold), the load will be disconnected after 12.0 seconds (Lower threshold disconnect delay).
After load disconnection, if the mains voltage increases above 195 V (“Lower disconnect threshold” plus “Hysteresis”), return to normal operation mode will occur after the AR time.
Product operation in emergency mode is described in the “Load Disconnection Due to Emergency” section.
In case of an emergency situation (voltage, current, power exceeding values, etc.), the load is disconnected, AR time countdown begins, and the “ENTER” button starts glowing red.
After the emergency situation disappears, the “ENTER” button starts flashing red with a 0.5 s period, indicating that the AR time countdown is in progress, after which the load will be automatically turned on.
If the AR time countdown ended before the emergency situation disappeared, then the load will be turned on without delay after the emergency situation disappears.
If the number of automatic reclosing attempts has been exceeded (for current and power protection — “3”, for voltage protection — “always”), the product will block load activation and the “ENTER” button will constantly glow red.
To restore product operation, disconnect it from the mains socket, wait 5 seconds, and plug it back in.
A single press on the “ENTER” button lasting 2-4 seconds switches the product to manual load control mode, with each button press turning on (if it was off) or turning off (if it was on) the load.
Press and hold the “ENTER” button on the front panel of the product
Plug the product into the mains socket and continue holding the button for 3 seconds. The “ENTER” button will start flashing blue-red quickly, then release the “ENTER” button
After the factory reset is complete, the “ENTER” button will stop flashing, and the product will perform an automatic restart.
Settings are reset to factory defaults and the product is ready for use.
