Setting the correct date and time ensures the digital timer functions precisely and keeps all schedules aligned.

Step-by-Step Guide:

Digital Timer Switch Date and Time Setting

Start by pressing the reset or main button to activate the timer. Go and clear previous settings if needed to avoid conflicts. Head into the menu and to the area where date and time is set. Use the designated buttons to adjust year, month, and day. It then sets the current hour and minute accurately. To save changes, you’ll want to confirm each step that you progress. To avoid getting incomplete settings or errors, follow the steps.

    • Timing and Pulse Setting

This setting allows devices to run automatically, as per your schedule, thereby reducing the amount of human control. Routines repeat on/off timing while pulse timing range is from 1 to 59 seconds. These features will take time to pay off by saving time, being more efficient, and preventing energy waste.

      • On/Off Timing Settings:

Digital Timer Switch On_Off Timing Settings

The “Prog” symbol on the display is turned on when a timing program is running. You can change this within the program menu by going to the timing options. You can set the ON and OFF times for your chosen days or weeks. Don’t let your schedules overlap so they aren’t in conflict with each other. Choose weekday combinations such as Monday to Friday or select your own combination. 

This feature is perfect for routines like turning morning (or night) lights on at sunset and off at midnight.

      • Pulse Program Settings:

Digital Timer Switch Pulse Program Settings

Short bursts of power as needed for signaling or water pumps are provided by pulsation. You have to configure the ON time and duration for setting it in the pulsation menu. The pulsation width may be set between 1 and 59 seconds. You will select specific days and confirm your choice. When pulsation mode is engaged, the screen pulses with a ‘P’ symbol to indicate that setup is complete.

    • Daylight Saving Time (DST) Display Settings

This setting automatically changes summer/winter time.Our software offers 2 options: EU standard and custom settings. You can customize the transition time, advancing/delaying 1 to 3 hours.

Setting Process:

Auto Change Summer_Winner Time

Go to the main settings and click on the DST menu. You can choose to set DST according to EU standards or as custom settings. You can advance/delay the summer/winter time switching time by up to 1-3 hours. There are custom settings for the start and end month, week and hour. Save changes are confirmed at each step. Delete the DST configuration, if DST adjustments aren’t needed.

Note: this setting changes the displayed time, but it doesn’t affect the programmed ON and OFF schedules.

    • Manual On/Off Setting

Manual settings allow quick control of connected devices during emergencies or temporary changes, bypassing automated programs.

Steps to Perform:

Manual ON_OFF Program Setting

Click the dedicated buttons to change the timer to manual ON > OFF operation. The correct buttons are used for Channel 1 or Channel 2 for two channel timers. Current status will be shown in the Auto for scheduled control, or in Force for manual override. Make sure this works correctly by confirming.

  • Astronomical Timer Switch Programming

    • Date, Time, and DST Settings

Accurate date, time and DST settings help the timer align with sunrise and sunset times for precise automation.

Visual Guide Step:

Astronomical Timer Switch Basic Setting

Open the settings menu to set date and time. Use the “+” and “-” buttons to set the year. However, in the same process you can adjust the month and day. Set the hours and minutes to exactly the current time. After each entry confirm to save changes. 

DST may be set using the DST menu. You can select from the EU standard, manual or delete the DST configuration. With manual settings, give the start and end month, week, and hour. Be careful to enter each input to save us from errors. This step verifies that the displayed time corresponded to daylight saving changes without changing the programmed ON/OFF events. 

Invalid DST configuration will generate discrepancies in your timer’s schedule during a year.

    • Longitude, Latitude, and Time Zone Configuration

This setting customizes the timer to your location for precise scheduling based on sunrise and sunset.

Steps by Step Guide:

Astronomical Program Setting

You can get longitude and latitude settings from main menu. Select East (E) or West (W), then enter the degree (0–180) you are entering the longitude. The second step is to set the latitude by choosing the point North (N) or South (S) and type the degree 0-68. Once you set coordinates, configure the time zone for it (+ or -12) compared to GMT. 

Suppose we need to set the astronomical timer switch for Los Angeles, California. Start by configuring the longitude. Enter 118° and select West (W). Next, set the latitude by entering 34° and choosing North (N). For the time zone, input -8 relative to GMT as Los Angeles follows Pacific Standard Time (PST). Once these settings are entered, the timer will display the local sunrise and sunset times.

If you want the connected system to turn ON at sunset and OFF at 10:00 PM, access the ON/OFF program menu, set the ON time to sunset and the OFF time to 10:00 PM

Important: To avoid timing errors in astronomical calculations you ensure that the coordinates and time zone are the same as your location.

    • On/Off Timing Program Settings

This setting automates device operation based on sunrise, sunset or custom schedules.

Steps with Visual Details:

On_Off Timing Program Settings

Select the timing type in the ON/OFF program menu. Set delays for ON (up to 99 minutes after sunrise) or early OFF (up to 99 minutes before sunset) for sunrise/sunset settings. Up to 16 programs can be specified with ON and OFF times for custom timings. Through the menu, you can assign programs to days or weeks. For two channel models, choose between Select Channel C1 or C2.

Tip: Compare program sequences to avoid overlapping times that will lead to conflicts.

    • Holiday Program Settings

Holiday settings provide the ability to stop execution of regular programs at defined periods such as vacations, holidays or maintenance days. So instead of editing or deleting existing schedules, you can temporarily set a break where things are no longer automated. 

Steps to Set Holidays Settings in Timer Switches:

Holiday Program Settings

From the main screen, enter the holiday settings menu. Next, you would select your wanted month and day to set the start date. You can navigate easily using the displayed options. Then set the end date the same way too when normal schedules will resume again. Make sure you’ve confirmed, then check the settings to confirm the holiday period is set correctly. 

This way, your schedule is kept in place and reappears when the set duration expires.

    • Manual On/Off Settings

The manual ON/OFF setting for the astronomical timer works the same way as the digital timer (section 1.4). It allows quick overrides for immediate control by using the same steps for toggling between automatic and manual modes.

  • Analog Timer Switch Programming

Analog timer switches provide simple and reliable control for scheduling devices. Here’s how to set and program the switch for efficient use. 

    • Set the Current Time

Set the Current Time

Use the timer dial to turn clockwise until the current time is correctly above the device pointer. Try to use a 24 hour timer, you don’t need to set AM/PM to prevent errors. True synchronized time is very important for correct scheduling.

    • Program On/Off Times

Connect the Device and Select the Timer Mode

  • Identify the On/Off Mechanism: The dial has movable pins or segments that represent time intervals.
  • Set ON Periods: You can push down or pull up the segments related to the time range based on which the connected device needs to turn ON.
  • Set OFF Periods: Leave the segments unchanged or adjust them for the time range when the device should remain OFF.

Example: For a 6:00 AM to 10:00 AM ON period, adjust the corresponding segments on the timer dial to cover this range.

    • Connect the Device and Select the Timer Mode

Put the device you want to control in the timer’s socket. Follow the programmed schedule and then set the mode control selector to “TIMER”. For constant operation, switch to “ALWAYS ON” Set it to “ALWAYS OFF” just to completely cut power.

    • Plug the Timer into a Power Source

Insert the timer switch into a wall socket and turn it on to activate.

Following these steps ensures that your device runs according to the schedule without manual adjustments. Analogue timers are great for simple automation needs like controlling lights, heaters or appliances.

 

General Considerations for Timer Switch Programming

  • Power Supply:

Check that the timer switch is powered by a compatible power supply as mentioned in the manual (this power supply: 85–265 VAC or 12/24/48 V AC/DC for models). Confirm the power supply is stable to avoid interruptions during programming.

  • Initial Setup:

Programming requires the timer switch to be put in an active state. Firstly, connect the analog timer to the power supply for one week before first use. For the display to appear, push the reset or activation button if it’s off. Learn to understand buttons and visual symbols as outlined in the manual so you can interact with menu properly.

  • Memory and Retention:

Make sure the timer has enough memory for the programs that you want to use (AHC610 series – 30 groups, AHC613/ AHC614 – 16 groups). Also note that the inbuilt lithium battery keeps settings even after power failure. Make sure they work to keep things going uninterrupted.

  • Sequential Programming:

Avoid overlapping times for ON/OFF programs. Programs must follow a logical sequence to prevent conflicts.

  • Configure DST Setting according to the Region:

Set DST based on region (EU or manual) Also ensure DST settings only modify the display time, not the ON OFF program timings.

  • Avoid Repetition:

Select appropriate combinations of days (weekdays only, weekends only or your own combinations). Get rid of redundant entries that use up much space in needed memory.
