Install dusk to dawn sensor ( Epiloque and a THANKS to all who assisted)
1- Please accept apologies if I don't communicate well as English is not my first language.
2- This issue was resolved as such; I installed a new switch ( from inventory), still had same problem. Installed a third swith, still same problem persisted.
I went to the store where they were purchased( had purchased five in total). I commented that perhaps the switches were bad. I asked for new switches from a different box.
I was given switches from a different box . Installed one of the new switches and it worked fine. I installed another on a second lamp pole, it worked fine.
I have to assume the switches I had purchased were from a defective batch.
The retailer got back to me today, he commented that he had given the sensors back to the representative who had contacted him confirming the sensors were in fact defective.
I don't access this forum often, however whenever I do there are always nice people willing to assist. Thanks to everybody who provided their expertise.
