Automag Relay Question
Hi All, new to the forum.
I recently purchased a home with an older Automag zone valve system. Oil furnace, hot water baseboard heat.
A recent problem has come up where all zones are heating when one zone calls for heat. I know that these automag zone valves fail open so I am thinking that this is an electronic problem as opposed to all of the valves being non-functioning. I have even replaced a few of the valve heads with new ones to confirm that and no change.
My question is I cannot seem to figure out what this separate relay is, it is on the side of the control board. It is hooked up to the hot water tank which I believe is the priority zone.
Here are some photos of the relay. There are no markings on it. The only similar relay that I was able to find is the Automag CNV84 ( picture attached)) which is a 3 wire to 2 wire relay. Is this what I should be changing out?
I dont think the problem is with the main control board, as thermostats are working correctly and kicking on/off furnace when it calls for heat. The problem is that power is not going to the valves to close them, and that the hot water tank is not regulating a constant temperature.
Thanks for any help or guidance you can give.

But I think you were over-charged for the strip of bacon :)

Boars Head Naturally Smoked Butcher Craft Extra Thick Cut bacon is 16.49 for 11 slices or 1.49 a slice. I used one and broke it into two pieces.
It's the half-pound of Angus beef that pushes it past the 2 dollar mark not to mention the service costs which vary widely from grill to grill.
That reminds me . . . I should probably bring my own burger to the pedmec BBQ this summer. Not that I'm getting invited.

Re: Two pipe Steam with no traps
Set us up with more pics of the boiler piping. Maybe I'm seeing things (or NOT seeing things-lol), but it seems to me that there is only one supply leaving the boiler to the two headers, and it kinda looks like maybe 2" copper. Can't see where the LWCO is, but I'm wondering if the low water trip isn't because water is backing out of the boiler (tough to do if the Hartford loop is there-and done right), but rather a slanting water level. When the boiler fires and you come up to steam, with only one supply, the water can tend to slant in that direction. The LWCO might be seeing this, depending on where it's physically located. With low water content boilers, it's usually recommended to go with two supplies, then into the header/equalizer. If it is slanting, you run the risk of overheating the rear section/s. Could also be caused by poor water quality leading to carryover or foaming. Could be caused by over firing. Let's see some more!
By the way-I've only seen a few systems like that one-2 pipe with no traps. Rarer than hens teeth. One I remember, a contractor had put traps in before we looked at it- thinking someone else didn't know what they were doing (80 years ago). Didn't work so well for them. Here's a pic of a device I found in that system that even stumped The Wall back when I ran into it...

That's kind of you, @tonynap. Thanks! Hard Rock Cafe, here I come. 😂 - Erin
Re: Replacement Hydronic system, cost of installation
I understand completely, have edited my posts, and ate the burger which was delicious.
Instead of cheddar used with Roquefort which bumped up the cost to . . . well, never mind.
Also, I just donated 21.99 to the website and only ask that Erin gets a proper burger for having to put up with this nonsense.
Have a great day.

Re: Replacement Hydronic system, cost of installation
If the price is too high then hire someone else that will do it cheaper. if nobody will do it cheaper then you know the price is not too high. it's that simple…
