Question about Intermatic T104R 208-277Volt 40-amp Timer Switch-Double Pole / Single Throw
You need to check the line voltage being supplied to the timer. It is possible that you have a reversed neutral and common (hot) line providing power to the timer. It is also possible to have another reverse situation with the way the timer is hooked up to the device it is controlling.
Timer motors should only operate in one direction, but if mis-wired, they can operate backwards.
I would need more information about the exact installation you have in order to provide a more thorough diagnois and solution. Info such as is this a 220V-AC installation; is the timer hooked to more than one (1) device (pump, etc.) ; Is there a GFCI breaker on this circuit (there should be!) ; Is this a new installation or a refurbished pool with a new pump & timer?
Please use the "comment" button to supply me with the info requested so I can better address your issue.
