• Power Input (L, N): Connect the live (L) and neutral (N) wires from your 220-250 VAC power source to the corresponding terminals.
• Relay Outputs (C1, 1, 2, C2, 4, 5): The TM612 has two independent relay outputs. Each relay has a common (C), normally open (NO), and normally closed (NC) contact.
  • Relay 1: C1 (Common), 1 (Normally Open), 2 (Normally Closed)
  • Relay 2: C2 (Common), 4 (Normally Open), 5 (Normally Closed)
  Connect your load (e.g., light, motor) to the appropriate relay contacts based on whether you need it to turn ON when the timer activates (NO) or turn OFF (NC).

3.2 Initial Power-Up

Upon initial power-up or after a prolonged power outage, the display may be blank. The internal rechargeable battery will charge automatically. Allow a few minutes for the display to activate. If the display remains blank, press the "Res" button to reset the device.
