Peter's been working on putting together a pigtail for us that transitions between the Irritrol MC-Plus controller circuit board to the Eicon remote receiver. I received the prototype pigtail yesterday and took it to work today to try it out. It matched right up on both ends and worked like a charm. Now we just need to get the budget in gear so we can have him make us 100 of these suckers. Thanks Peter for a job well done!
