I had a wired system but my dog has now ruined two gauges and gets to the wires way to often because of the crappy install point. I bought an WR2-RC to hook up to my ESP-4Mi. I removed the jumper that was installed for the wired system and placed the green and white into the points where the jumper was for the sensor. Then I attached the red and black to the 24v supply. Unit has power but couldn't get it to run after placeing batteries in the wireless unit and following the set up. I can't figure out where the wired guage runs to. I have a red and black cable that go to the Comm and MV tabs also. I also tried attaching the black wire from the wireless unit with the green wire but this kicked the power off to the wireless wall unit. Any help to set up would be appriciated.
