I might be interested I've installed the system before and was thinking of replacing my touch plate with them. How much for 4 of them?Bigbitt62 said:Yes surfaced mounted......16 circuit 120/277. I am not sure how much I want. They were hardly used. My customer had switched over to a different energy management system and I removed these. I am trying to see what the price of a new one is.....and go from there.....I have one in my home and it controls everything from my pool, outside lighting.....even controls my septic holding tank pump! Works great on the pool because of the override controls. All of mine also have the capability to connect a phone line into the control panel. RJ45 modem in every one of them! Awesome box!
