3. About the Device

The Device is a DIN rail mountable smart switch with potential-free contacts. It controls on/off

function for one electrical device (with load up to 16 A), e.g., bulb, ceiling fan, IR heater,

electrical locks, garage doors, irrigation system, etc. and it is compatible with push-buttons and

switches (default).

If the SW (SW1) is configured as a switch, each toggle of the switch will change the output O

(O1) state to the opposite state - on, off, on, etc. If the SW (SW1) is configured as a push-button

in the Device settings, each press of the push-button will change the output O (O1) state to the

opposite state - on, off, on, etc.
