Hello Momin,

You need to go into more detail with your description so that someone can help you. And upload the program too.

However, the current scenario is that the units change over at different times, as set on the individual timers. The client requires all units to change over during the daytime only, for example, at 10 AM, because currently, some units are changing over at midnight based on their set timers.

The way you describe it, you only need to move the switching times to the day...

- Require weakly timer block programming as On/off Timing, weak selection as per attached program 

Hello Momin, Unfortunately,

your two descriptions are not very clear. They also contradict each other in some ways.

As I understand it, however, the system switches to a different unit every day at 10:00 a.m. If the current unit is faulty or inactive, it should switch to the standby unit.

If my assumption is correct, my modification of your program will definitely help you.
