Have a problematic Lula that is older and has had issues - couple years ago we changed the controller over to a Virginia Controls controller, new wiring, new selector (IP8300), some new switches but overall mostly same equipment just a controller and wiring change.... Door Operator was crap then and they were told but decided to leave it for cost reasons. Well few months ago the operator died and now after a lot of searching we found a replacement - We are replacing it with a Wittur Door Operator. Never worked with Wittur equipment, obviously manufacturer is saying its simple and easy. Just looking for any tips or tricks on this or any info at all with these operators

Side note - building is a church, money is tight for them which is why only little pieces are being changed out each time.

Appreciate any help
