Frequently Asked Questions - TYA664A HAGER
How do I program the timer for daily operation?
Press PROG to enter programming mode. Use + and - to set the desired on/off times. Confirm with OK. The timer will execute the schedule automatically.
What does the reset button do?
The RESET button (recessed) clears all programmed settings and restores factory defaults. Use a paperclip to press it.
How long does the backup battery last?
The built-in lithium battery maintains the program for up to 5 years during power outages. When the battery is low, the display will show a warning symbol.
Can I manually override the timer?
Yes, press the MAN button to toggle between auto, on, and off modes. The manual override remains active until the next programmed command.
Why is the display blank?
Check that the mains power is connected and the circuit breaker is on. If the display remains blank after power restoration, the backup battery may be depleted. Replace the battery or contact support.
How do I set the current time and day?
Hold the SET button for 3 seconds. Use +/- to adjust the time and day. Press OK to confirm each setting.
What is the holiday function?
The holiday function allows you to set a random on/off pattern during your absence to simulate presence. Activate it in the menu: MENU > HOLIDAY.
Can I connect multiple devices to this timer?
The TYA664A is a single-channel timer, so it controls only one load (up to 16A resistive). For multiple devices, use a contactor or install additional timers.
How do I clean the device?
Disconnect the power. Wipe the housing with a soft, dry cloth. Do not use water, abrasive cleaners, or solvents.
What should I do if the timer is not switching correctly?
Verify the programming schedule and ensure the manual override is in AUTO mode. Check the load rating and wiring. If the problem persists, perform a factory reset.
