3. Produktua amaitu daview
The Intermatic MIL72ESTUZH-120 is a robust 24-hour electromechanical timer module designed for flush or panel mounting within a control panel. It is suitable for light-duty commercial applications requiring precise time control for 120 VAC single-phase circuits. Common uses include lighting, HVACR systems, pumps, motors, and general electrical circuit management.

Irudia: Aurrealdea view of the Intermatic MIL72ESTUZH-120 timer. The device features a clear protective cover over a black dial. The dial displays a 24-hour format with AM/PM indicators and minute markings. A central clock mechanism with hour and minute hands indicates the current time. The outer edge of the dial contains captive trippers for setting ON/OFF periods. A manual override switch is visible on the right side of the dial.
Ezaugarri nagusiak:
- 21 A SPDT Switch: Provides reliable switching for various loads.
- Synchronous Drive with Self-Recharging Battery Backup: Ensures accurate timekeeping and operation during power outages.
- Captive Trippers: Allows for easy setting of 15-minute ON/OFF intervals.
- Eskuz gainditzea: Provides flexibility to temporarily bypass programmed settings.
- Muntaiaren diseinua: Integrates seamlessly into control panels.

5. Instalazioa
Hasi aurretik:
- Ziurtatu zirkuitu-etengailu nagusian korrontea itzalita dagoela.
- Egiaztatu hornidura voltage matches the timer's rating (120V AC).
- Have appropriate tools ready (screwdriver, wire strippers, etc.).
Muntaketa:
- Select a suitable location within a control panel for flush mounting.
- Cut an appropriate opening in the panel according to the timer's dimensions.
- Insert the timer into the opening and secure it using the provided mounting hardware.
Kableatua:
Refer to the wiring diagram provided with the product packaging for specific connections. General wiring steps include:
- Connect the incoming 120V AC line wire to the designated terminal.
- Konektatu kable neutroa terminal neutrora.
- Connect the load wire(s) (e.g., to lights, motor) to the appropriate switched terminals (normally open or normally closed, depending on desired operation).
- Ziurtatu konexio guztiak seguru eta isolatuta daudela.
After wiring, restore power and proceed to initial setup.
6. Funtzionamendua
Uneko ordua ezartzea:
- Rotate the entire dial clockwise until the current time aligns with the time indicator arrow (usually a small triangle or line on the stationary part of the timer housing).
- Ensure you distinguish between AM and PM hours on the 24-hour dial.
ON/OFF programak ezartzea:
The timer uses captive trippers around the dial to set program times. Each tripper represents a 15-minute interval.
- 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 for the desired duration.
- The timer will activate the connected load when the dial rotates past an outward-pushed tripper and deactivate it when it rotates past an inward-pushed tripper.
Eskuz gainditzea:
The MIL72ESTUZH-120 features a manual override switch, typically a small lever or button, located on the timer face. This allows you to temporarily switch the load ON or OFF, overriding the programmed schedule without affecting future cycles.
- Move the override switch to the desired position (ON or OFF).
- The timer will resume its programmed schedule at the next scheduled ON or OFF event.
7. Mantentzea
The Intermatic MIL72ESTUZH-120 is designed for minimal maintenance.
- Garbiketa: Periodically wipe the exterior of the timer with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Bateria: The unit contains a non-replaceable, self-recharging Nickel Metal Hydride battery for power outage carry-over. No user maintenance is required for the battery.
- Ikuskapena: Annually inspect the timer for any signs of damage, loose connections, or unusual operation. If any issues are found, disconnect power and consult a qualified electrician.
