- Configuració de l'hora actual: Rotate the clock dial in the direction of the arrow until the current time aligns with the time indicator mark. The clock face is marked with AM/PM for clarity.
- Configuració dels horaris d'encesa/apagada: The timer features 96 captive trippers around the dial, each representing 15 minutes. To set an ON period, push the trippers outwards for the desired duration. To set an OFF period, leave the trippers in their inward position.
- Interruptor d'anul·lació manual: The module includes a 3-way override switch (often labeled ON, AUTO, OFF or similar symbols).
- Posició ON: Forces the connected load to remain ON, overriding the programmed schedule.
- Posició automàtica: Allows the timer to operate according to the programmed ON/OFF schedule.
- Posició OFF: Forces the connected load to remain OFF, overriding the programmed schedule.
6. Manteniment
The Intermatic FM1STUZH-120U Electromechanical Timer Module is designed for reliable, long-term operation with minimal maintenance. Regular inspection of wiring connections for tightness and signs of wear is recommended. Keep the unit free from dust and debris. No user-serviceable parts are inside; refer to qualified personnel for any repairs beyond basic installation and operation.
7. Solució De Problemes
- Timer Not Operating: Check the power supply to the module. Ensure the manual override switch is in the 'AUTO' position. Verify that the captive trippers are correctly set for ON periods.
- Càrrega no commutadora: Confirm that the load is properly connected to the timer's output terminals. Check the load itself for functionality. Ensure the timer is receiving power and the internal mechanism is rotating.
- Horari incorrecte: Verify that the current time is accurately set on the dial. Ensure the ON/OFF trippers are correctly positioned for the desired schedule.
- Funcionament intermitent: Inspect all wiring connections for looseness or corrosion. Ensure the operating environment is within the specified temperature range.
If issues persist after performing these checks, contact Intermatic customer support or a qualified electrician.
