1.3. The wires are connected according to the diagram:
1 – heating element phase *
2 – heating element neutral *
3 – mains neutral
4 – mains phase

On sides 1 and 2, the connections are for the thermostat; the order of the wires does not matter.
* In most cases, the polarity of heating elements is not important.
The maximum allowed load is 16 amps, which equals about 3500 watts at 230 volts.
Please note:
1) Stranded wire ends must be crimped with ferrules or soldered. Solid wires do not require ferrules.
2) If the power exceeds 2000 W, the wire cross-section must be at least 2.5 mm².
3) The heating device must be grounded.
After connecting the wires, install the thermostat into the junction box, attach the display connection cable, and press the display back into its original position.

8 – Power-on indicator (heating element energized)
9 – Operating mode (manual or automatic)

2.2. To set the time, tap the clock icon once (button 2 in the bottom row). The hour digits will start blinking—use the up or down arrows on the right to select the correct hour.
Tapping the clock icon again activates the minute setting. Use the same up and down arrows to adjust the minutes.
On the third tap of the clock icon, the day of the week selection is activated.
On the fourth tap, the settings are saved.

2.3 There are two operating modes: manual (hand icon indicator) or automatic (time and temperature).

2.3.1 To activate manual mode, press the “M” button until the hand icon appears in the operating mode. Then use the arrow buttons to select the desired temperature.

2.3.2. The indicator for automatic mode is the clock icon. When it is illuminated, the following preset is applied.

To change the preset, turn the device off and then press and hold the “M” and clock buttons simultaneously for five seconds. The setup menu will then appear on the screen, showing the preset fields. The active field will blink and can be adjusted using the arrow buttons. Pressing the “M” button moves to the next field. When the setup is complete, confirm by pressing “M.”

2.4 The device has frost protection. It switches on when the temperature drops below 5 °C and switches off when the temperature rises above 7 °C. By default, overheating protection is activated at 60 °C.

2.5 Advanced settings allow you to change the device’s operating parameters and perform the initial setup. To access this menu, turn off the device and press the “M” and down arrow buttons. Use the “M” button to switch between options. To exit the mode, press the power-off button.
