Hi, thank all of you in advance for an assist.
I have both an EA-5 and HC800 in my living room rack. The HC800 used to do more than it does now. Currently, the HC800 only turns on/off the fireplace (Relay 2), turns up the fireplace (Relay 1) and turns down the fireplace (Relay 3).
I am attempting to remove the HC800 completely by moving the fireplace control to the EA-5. The problem is that the relays in both machines do not work the same. I have photographed both relay layouts on back to compare. They are identical. I used the wiring block of the HC800 and plugged directly to the EA-5. Then I changed the connections over to the EA-5.
Correct Response from HC800: On/Off works, fp turns up in increments and turns down in increments
Outcome from EA5: On/Off doesn't work, fp goes all the way up (no increments) and all the way down (no increments) when I hit corresponding buttons.
Why 2 different outcomes?
