replacing dimmer need help (wall has 2 wires, dimmer has 3+ground)!
the wall has
1 Black
1 Red
when I use a electrical detector the black one is the hot one
my dimmer has
1 red, 1 black, 1 white, 1 green (ground)
RF9537-NAW 1000W Electronic Low Voltage (ELV)
I tried connected in any combination but no go.
I thought maybe I need an accessory type of dimmer so I used this
RF9547-ZAW
1 black, 1 white, 1 green (ground)
still no go... what am I missing?

The first dimmer requires a neutral to operate.
The second unit appears to be the remote for the first dimmer.... probably for 3 way applications.
You are showing us a junction box with a red and black wire only. I don't see any other wires in the box. That tells me that you have a metal conduit system and just a switch leg there with no neutral. You may be able to locate the other end of that conduit and pull a neutral to that point.

Two questions:
- Does that dimmer have a special feature that you want to have that requires a neutral connection? Does it light up or something?
- What type of lamps (light bulbs) will be controlled by the dimmer?
