True, I would have thought it would read open. When I break something, it stays broken. I actually bought it on Amazon. It had instructions, but for some stupid reason, I thought the diagram was telling me to connect neutral to C. There are about 6 different diagrams on the sheet. I just...

I tried that a little while ago, A to B is always low resistance. Looks like I buggered it when I hooked it up wrong the first time. Oh well, moderately priced lesson learned...

A switched neutral makes no sense at all. Can you provide a link to the diagram? Tell me about it... It made no sense to me either, but since I'm not an electrician or plumber, I figured somebody must know. I must have been hallucinating, though, because now I can't find anything that...

Thanks - Of course, the instructions show examples for every type of system you could want, except the one you have... The "switched neutral" confused me too, but that's what I found on another forum on a diagram that looked a lot like my situation. It made sense, the neutral is broken by a...

Thanks for the help, guys. I probably am in over my head. I'll ask my boiler guy when he comes to service it.

I will have to assume when you say time switch you are talking about what I referred to as the controller. That is a Honeywell ST6400C. Obviously I'm new to this and don't know all the requirements and terminology, otherwise I would have just plugged my crystal ball into my ford ideal boiler...

I decided to replace my fully functional T6360 room thermostat with a more efficient CM900 automatic digital thermostat. After several hours and a couple of blown fuses, I'm a bit stuck. I have an Ideal boiler, which has its standard controller. That controller is set to an auto program for...
