6. Иштөө нускамалары
The T104R timer operates on a simple mechanical principle, allowing for straightforward daily scheduling.
6.1 Setting the Time of Day
- To set the current time, gently pull the yellow dial outwards.
- Rotate the dial in either direction until the current time aligns with the arrow or mark on the timer mechanism.
- Push the dial back in to engage the mechanism.
6.2 Программалоо КҮЙГҮЗҮҮ/ӨЧҮРҮҮ убакыттары
- The timer comes with one "ON" tripper (green) and one "OFF" tripper (red). Additional trippers can be purchased separately.
- To set an "ON" time, slide the green tripper onto the dial at the desired hour. Ensure it is securely fastened.
- To set an "OFF" time, slide the red tripper onto the dial at the desired hour. Ensure it is securely fastened.
- The timer will activate the load when the "ON" tripper passes the trip mechanism and deactivate when the "OFF" tripper passes it.
- The minimum interval between an ON and OFF event is 1 hour.

6.3 Кол менен жокко чыгаруу
The T104R features a manual override lever located below the dial. This lever allows you to temporarily turn the connected load ON or OFF without affecting the programmed schedule. Simply move the lever to the desired position (ON or OFF). The timer will resume its programmed schedule at the next scheduled ON or OFF event.
7. Техникалык тейлөө

8. Кыйынчылыктарды
If your Intermatic T104R timer switch is not functioning as expected, consider the following common issues and solutions:
| Көйгөй | Мүмкүн себеп | Чечим |
|---|---|---|
| Таймер программаланган убакта КҮЙГҮЛҮП/ӨЧҮРҮЛБӨЙТ. | Trippers are not securely placed or are incorrectly positioned. | Ensure ON and OFF trippers are firmly snapped onto the dial at the correct times. Verify the manual override lever is not engaged. |
| Таймердин баскычы айланбай жатат. | No power to the timer; internal motor failure. | Check the circuit breaker. Ensure wiring connections are secure. If power is present and the dial still doesn't move, the internal motor may need replacement or professional servicing. |
| Load (e.g., pump, light) is not receiving power. | Timer is in OFF cycle; wiring issue; faulty load. | Check the timer's current position on the dial. Use the manual override to test the load. Verify all wiring connections are correct and secure. Test the load directly if possible. |
| Timer is losing or gaining time. | Power interruptions; internal motor issue. | Mechanical timers require manual reset after power outages. If time drift occurs without power interruptions, the internal motor may be failing. |
For issues not covered here or if troubleshooting steps do not resolve the problem, contact a qualified electrician or Intermatic customer support.
