Set the current day and time, choose when your equipment turns ON and OFF, then leave the timer in AUTO. Follow the simple daily example before adding more schedules.
Do this first. The timer needs to know the real time before it can run your schedule. CLOCK is the button marked with a clock symbol.
Example: For Monday at 2:30 pm, set MO 14:30. The timer uses a 24-hour clock: 08:00 is 8 am; 18:00 is 6 pm.
If your timer has a keypad lock
If a lock symbol is visible, press C/R four times to unlock. The supplied sheet says lock-equipped versions set the live clock with D+, H+ and M+ directly after unlocking. Use the controls for your version.
An ON setting tells the timer when to supply power to the connected equipment.
Everyday example: Select MO TU WE TH FR SA SU, then set 08:00.
Minimum programming interval: 1 minute
Set ON and OFF times using H+ and M+. This timer does not support programming in seconds.
The matching OFF setting tells the timer when to stop supplying power.
Everyday example: Select MO TU WE TH FR SA SU, then set 18:00.
Complete both halves of the schedule
Setting only 1 ON does not create a switch-OFF time. For this same-day example, set both 1 ON and 1 OFF with the same days.
| Display | What it does |
|---|---|
| ON | Keeps the output switched on manually. |
| AUTO | Runs the saved schedule. |
| OFF | Keeps the output switched off manually. |
After a manual test, always return to AUTO. Do not assume switching to AUTO immediately changes the output; check the next scheduled event.
Use one program pair to run equipment from 8 am to 6 pm every day.
| Screen | Days to select | Time |
|---|---|---|
| 1 ON | MO TU WE TH FR SA SU | 08:00 |
| 1 OFF | MO TU WE TH FR SA SU | 18:00 |
| Normal clock | Today's actual weekday | Current time |
| Operating mode | AUTO | Saved schedule active |
Button sequence: CLOCK + D+/H+/M+ → P → set 1 ON → P → set 1 OFF → CLOCK → MANUAL to AUTO.
For weekdays only, choose MO TU WE TH FR on both program screens.
| Button | Function |
|---|---|
| CLOCK (clock symbol) | Set the live clock; return from programming. |
| D+ | Select weekday or day group. |
| H+ | Set the hour. |
| M+ | Set the minute. |
| P | Open and review ON/OFF programs. |
| MANUAL | Select ON, AUTO or OFF on the live display. |
| C/R | Clear or recall the selected program; unlock supported versions with four presses. |
| C (recessed) | Reset timer settings. |
Reset is not needed for everyday setup
The recessed C button resets settings. Record your schedule before using it, then check and re-enter the clock and programs as needed.
Press D+ while viewing an ON or OFF program. Stop when the required days are displayed; use the displayed days rather than counting button presses.
| Displayed days | Runs on |
|---|---|
| MO TU WE TH FR SA SU | Every day |
| MO TU WE TH FR SA | Monday–Saturday |
| MO TU WE TH FR | Monday–Friday |
| SA SU | Saturday and Sunday |
| MO WE FR | Monday, Wednesday and Friday |
| TU TH SA | Tuesday, Thursday and Saturday |
| MO TU WE | Monday, Tuesday and Wednesday |
| TH FR SA | Thursday, Friday and Saturday |
| MO / TU / WE / TH / FR / SA / SU individually | One selected weekday |
The eight groups plus seven individual weekdays provide 15 day selections.

Review or remove a schedule
Do not use 00:00 to mean cleared: midnight is a valid switching time. Avoid overlapping schedules until you have tested how the complete sequence operates.
| Item | Reference |
|---|---|
| Programming | Daily or weekly ON/OFF schedules |
| Capacity | Up to 28 ON/OFF pairs, according to the supplied sheet |
| Display | LCD with 24-hour clock |
| Time setting | Hours and minutes |
| Minimum programming interval | 1 minute |
| Supply | Use only the voltage and AC/DC type marked on your unit |
| Clock accuracy | Original sheet: approximately 1 second/day at 25°C |
| Power consumption | Original sheet: ≤2 W |
| Ambient temperature | Original sheet: −10°C to +40°C |
| Ambient humidity | Original sheet: 35–85% RH |
The minimum programming interval is 1 minute. The clock accuracy specification describes timekeeping error, not the switching interval.
This supplied diagram shows the four-terminal switched-supply AC version. Other versions can have a different output arrangement.
| Terminal | Connection in this diagram |
|---|---|
| 1 | POWER L — incoming live |
| 2 | POWER N — incoming neutral |
| 3 | LOAD N — load neutral |
| 4 | LOAD L — switched live to the load |
For DC or volt-free-contact versions, follow the diagram on that specific unit; do not apply this AC L/N diagram to them.
Disconnect power before wiring
Mains wiring must be performed by a qualified electrician. The 25 A marking in this illustration is not a rating for every model or load type. Follow the supplied unit's rating and use suitable switching equipment for the connected load.
Check the live weekday and 24-hour time first. Then review the ON and OFF times and selected days. 18:00 means 6 pm.
Return to the clock display and confirm AUTO, not forced ON or OFF. Check that both halves of the schedule are set, then observe the next scheduled event. If it still fails, have the supply, load and wiring checked safely.
If your version shows a keypad lock symbol, press C/R four times to unlock. Do not press the recessed C reset button just to unlock.
The minimum programming interval is 1 minute. Set the hour with H+ and the minute with M+. This timer does not support programming in seconds.
Review the D+ day group for every active ON and OFF entry. For the same-day examples in this guide, both entries must use the same days. Check unused programs for extra events.
Check the live clock, saved programs and AUTO mode before relying on the timer. A retained display or program does not mean the connected equipment has power.
