A: Yes, but you must use external relays or solid-state isolators. Do not directly connect the trigger output of one to another without proper voltage matching.

| Problem | Likely Cause | Solution | |----------------------------------|-----------------------------------------------|-----------------------------------------------------------------------| | Display stays off | Power supply issue or reverse polarity | Check voltage at VCC/GND. Ensure correct polarity. | | Relay does not activate | Wrong mode selected or no trigger signal | Verify mode (e.g., P1 requires trigger). Use a jumper on IN pin. | | Timer runs but relay chatters | Load exceeds relay rating or inductive spike | Reduce load. Add a snubber or diode across the load. | | Buttons unresponsive | Lock mode enabled (if featured) | Power cycle device. Press and hold START + SET for 5 seconds. | | Display shows "Err" or "----" | Invalid time setting (e.g., T1=0 with T2>0) | Re-enter programming and set T1 to at least 1 unit. | | Trigger doesn’t start timer | Wrong signal level (3.3V vs 5V/12V) | Apply >70% of supply voltage to IN pin. |

Clean the filter; Ensure room is within operating temp; Clear obstructions around unit. Misaligned or loose drain hose connection.
