Digital Inputs
The device is equipped with 4 digital inputs.
The I1 and I2 inputs are dedicated to control the light by connecting monostable or bistable switches. The I3 and I4 inputs are used to connect occupancy sensors (or occupancy sensor and light 2 control switch) in the LLC mode. In case the LLC mode is set to operate in 1 zone, the I4 input can be used for switching the light, using the light 2 relay output. Each pulse on I4 (pushing the monostable button) switches on or off the light 2 output.
The way of connecting signals is presented in the figure below.
