1 Purpose
Section titled “1 Purpose”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.

7 Product Operation Description
Section titled “7 Product Operation Description”The product operation description uses the manufacturer’s default settings.
Normal Product Operation
Section titled “Normal Product Operation”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.
Load Protection by Mains Voltage
Section titled “Load Protection by Mains Voltage”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.
Load Protection by Consumption Current
Section titled “Load Protection by Consumption Current”During operation, EM-126T constantly measures the current consumed by the load.
In case of load current increase above the 10 A threshold (Disconnect threshold), the load will be disconnected after 5.0 seconds (Disconnect delay).
After load disconnection, 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.
Load Protection by Consumption Power
Section titled “Load Protection by Consumption Power”During operation, EM-126T constantly measures the power consumed by the load.
In case of load power increase above the 2300 W threshold (Disconnect threshold), the load will be disconnected after 5.0 seconds (Disconnect delay).
After load disconnection, 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.
Load Disconnection Due to Emergency
Section titled “Load Disconnection Due to Emergency”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.
Load Control from the Front Panel
Section titled “Load Control from the Front Panel”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.
Factory Reset
Section titled “Factory Reset”To reset to factory settings:
- Unplug the product from the mains socket
- Disconnect the load from the product socket
- 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.
Data Exchange Protocol Between EM-126T and “my.overvis.com” Server
