I am installing this switch and all works OK, except the LED on the switch is flashing red. I see from discussions that this means the RF is not working. I also saw that I might need to the install the MRC that came with the switch. Here is my confusion. I am using this switch because I don't have a neutral for this switch. The PD5WS-DV does not require a neutral. Yet all of the instructions I have found for installing the LUT-MRC shows installing across the switch hot and the neutral.
Is there another way to install the MRC? Will it really solve my flashing red led?
