The controller can operate in one of three modes
- Normal - i.e. each relay can be independently switched on and off
- Impulse - a function set separately for each relay - it is possible to set automatic switching off of a relay after a specific time, the so-called impulse control used in gate control
- Link (interlock) - this function causes only one of the four relays to be switched on at a time, switching on one relay automatically switches off the other, a function used in control of roller shutters and motors.
The relay mode is configured from the eWeLink application.
