Will the Leviton 32120-1 whole house surge suppressor or, Leviton DHC System Amplifier/Repeater/Coupler Module; HCA02-10E adversely affect UPB signaling or devices?
Thanks, Scott
It is claimed about 10% of the homes in the US require a UPB Phase coupler.
I have found you will know in the beginning. Unlike X-10 they may not need it now but may later, UPB seems to be now or never. I installed switches in a clients home of 6k square feet. I had to install it immediately to get all switches working.
For professionals it is always safer to use it and not need it.
Homeowners, I suggest wait until you need it... you may not. HAI's phase coupler is about the same prices as a light switch.
I have yet to dicover a problem in UPB in reliability and speed. I use them, and like the felxability in programming they provide.
