3. Installation and Wiring

Installation Methods

It supports rail-mounted, wall-mounted, and device-mounted installations. Among them, rail-mounted installation is simple and quick, suitable for various scenarios such as homes and offices.

Wiring Methods

Direct Control Mode: When the controlled electrical appliance is single-phase powered and its power consumption does not exceed the rated value of this switch, the direct control mode can be adopted.

Single-Phase Capacity Expansion Mode: When the controlled electrical appliance is single-phase powered but its power consumption exceeds the rated value of this switch, an AC contactor with a capacity exceeding the electrical appliance’s power consumption is required for capacity expansion.

Three-Phase Working Mode: When the controlled electrical appliance is three-phase powered, an external three-phase AC contactor is required. The coil voltage of the contactor is divided into two types: AC220V, 50Hz and AC380V, 50Hz.

4. Setting Methods

Unlock: Press the “Cancel/Resume” button 4 times consecutively to unlock.

Time Calibration: Press the “Hour Calibration” button to set the hour, the “Minute Calibration” button to set the minute, and the “Week Calibration” button to set the week.

Set Switching Time:

Press the “Manual” button to make the triangle on the display point to the “Auto” position. Then press the “Set” button to enter the “On Setting”. Press the “Week” button to set whether it is the same every day, different every day, the same from Monday to Friday, or the same from Saturday to Sunday. Then press the “Hour” and “Minute” buttons to set the on time. Next, press the “Set” button to enter the “Off Setting”, and press the “Hour” and “Minute” buttons to set the off time. Repeat the above steps to set multiple groups of switching times.

Check and Modify: Press the “Set” button to check whether all set times are correct. If modification is needed, press the “Cancel” button at the setting point, and then re-set the switching time and week.

End Setting: Press the “Clock” button to end the check and setting, and display the clock.
