1. Producte acabatview
The Intermatic MIL72ASTUZH-24 is a 24-hour electromechanical timer module designed for integration within control panels. It supports both surface and DIN rail mounting configurations. This timer is suitable for light-duty commercial applications requiring 24 VAC single-phase control, such as lighting systems, HVACR equipment, pumps, motors, fan controls, access control systems, and general-purpose electrical circuits. The unit includes a pre-installed, non-replaceable Nickel Metal Hydride battery for internal functions.
This device features a synchronous drive mechanism and a 21 Amp SPDT switch. It is equipped with captive trippers that allow for 15-minute interval programming. Electrical connections are made via 1/4-inch quick-connect terminals. A 3-way override function provides manual control flexibility.

6. Funcionament
The MIL72ASTUZH-24 operates on a 24-hour cycle, allowing for precise scheduling of connected devices. As a synchronous drive timer, it relies on continuous power for timekeeping. In the event of a power outage, the timer will stop and will not automatically resume at the correct time when power is restored.
- Estableix l'hora actual: Rotate the outer 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). The dial is marked with AM/PM indicators. If a power outage occurs, you will need to reset the current time.
- Horaris d'encesa/apagada del programa:
- The dial has captive trippers around its circumference. 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.
- The timer will activate the connected device when the dial rotates to an "ON" (outward) tripper and deactivate it when it rotates to an "OFF" (inward) tripper.
7. Anul·lació manual
The timer features a 3-way manual override switch, typically located on the front of the unit. This switch allows for temporary control of the connected load without affecting the programmed schedule.
- AUTOMÀTIC: El temporitzador funciona segons l'horari programat.
- ACTIVITAT: The connected device is continuously ON, overriding the schedule.
- DESACTIVAT: The connected device is continuously OFF, overriding the schedule.
Return the switch to the "AUTO" position for the timer to resume its programmed operation.
8. Manteniment
The Intermatic MIL72ASTUZH-24 is designed for minimal maintenance. No routine user maintenance is required.
- Neteja: If necessary, gently wipe the exterior of the timer with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Bateria: The unit contains a non-replaceable Nickel Metal Hydride battery for internal functions. This battery is not user-serviceable.
