Digital Timer Daily and Weekly Program 1ROM2ER Revalco

The Revalco 1ROM2ER is a din rail digital timer that runs both daily and weekly programs from the same unit. Set a schedule that repeats every day, or build a weekly pattern where weekdays and weekends behave differently, which is what most real installations need. Eight ON and OFF programs give enough slots to cover a full working week without compromise.

The battery reserve is the practical detail that matters on site. If the supply drops, the clock keeps running for up to 300 hours, so the timer comes back with the correct time and schedule intact instead of flashing at zero and needing a reprogram. On a lighting board or a pump panel that saves a callout every time there is an outage.

A minimum setting interval of 1 minute allows precise switching rather than rounding to the nearest quarter hour. MANUAL ON, AUTO and MANUAL OFF modes let an operator override the schedule without losing it, and 12 or 24 hour display plus a SUMMER and WINTER function handle local clock conventions and seasonal changes. The unit clips onto standard din rail and sits in the board alongside the breakers it controls.

The 1ROM2ER is listed in the Daily and Weekly Timer range, which covers every scheduling timer we stock. For the full selection including analog and cyclic models, see Digital and Analog Timers.

If the schedule needs to follow sunrise and sunset instead of fixed clock times, an astronomical timer is the better fit. The Hugo Muller 172413 astronomical timer adds daily, weekly and astronomical programs with 60 memory locations and a 16A switching capacity on din rail. The Hugo Muller 170413 is a simpler single channel version with NFC app programming, and the Hugo Muller 173113 is the flush wall mounted equivalent for installations without a din rail board.

FAQ,s

What is the difference between a daily and a weekly timer program?

A daily program repeats the same ON and OFF times every day. A weekly program lets each day of the week have its own schedule, so weekends can run differently from weekdays. The 1ROM2ER supports both.

How many switching programs does it have?

Eight ON and OFF programs in total, which is enough to cover several switching events across a full week.

What happens during a power cut?

The battery reserve keeps the clock running for up to 300 hours. When power returns the timer resumes with the correct time and the programs still stored.

Can the schedule be overridden manually?

Yes. MANUAL ON, AUTO and MANUAL OFF modes let an operator force the output on or off without erasing the programmed schedule.

Does it adjust for seasonal clock changes?

The SUMMER and WINTER function adapts the timer to legal hour changes, so the schedule stays correct when the clocks shift.

What size is it on the rail?

The body measures 85mm high, 35mm wide and 58mm deep, which is two standard modules on 35mm din rail.
