How to use

Install the relay on a standard DIN rail inside an appropriate distribution enclosure and connect supply and load conductors following local electrical regulations. Use the manufacturer's Bluetooth-capable application on a smartphone or tablet to pair with the unit, configure channel-specific time programs, and set manual or automatic modes. Verify correct operation by testing each channel’s switching function and confirm that schedules activate the connected loads at the intended times.

Recommendations

Ensure installation and wiring are performed by a qualified electrician and comply with applicable safety standards. Use the Bluetooth configuration only within secure proximity to the device and keep software up to date. For loads near the relay's rated limits, verify inrush currents and consider protective measures or contactors for inductive or high-start-current devices.
