What do you have for a boiler? brand and model please
It's not a Honeywell. Honeywell doesn't make boilers. You might have a Honeywel control (or 2) on the boiler but that's all. There should be a rating plate/tag on the boiler with the model number. If not I need you to remove the cover from the Honeywell control on the side of the boiler (not the burner) and give me a picture of the wiring connections inside. Actually I could use that picture even if you can give me the brand and model of the boiler. You can post a pic here by clicking on ADD FILES next to the SEND button
Ok, I'll get back to you as soon as I can
Please don't respond again until you have the info I need. I have to answer every one of your posts
Thanks for the pics but none of them are what I asked for. I need you to remove the cover on the gray Honeywell control box that mounted on the front of the boiler (top left) and give me a picture of the inside so I can see the electrical connections. Also how many thermostats do you have? from what I can see in the pics you should have at least 3
You're pictures don't help. I asked for a picture showing the connections inside the control. The angle of your picture doesn't show me any of the connections in the control. The pic of the junction box doesn't help now maybe it will later. I also asked about your other thermostats. Please answer that question as well. What I see indicates to me that you should have 3 thermostats not 2 unless you have an indirect fired water heater. I also need to know what you have for pump relays (brand and model) and a picture of the connections in the relay(s). The pump wire/cable is connected to the relay(s)
Still not what I need. I need to see the actual wiring connections inside the control not a wiring diagram. And I also need to know what you have for pump relays and the wiring connections inside the relay(s). An overall picture of the boiler and surrounding piping might also help.
I'm going to open this backup to my colleagues so one of them can help. Please don't respond (even to acknowledge this post)until you get a response from us. If you respond first it will only delay your answer.
