Argo Switching Relays

Nick Geragotelis

Do you know if I can connect the Argo ARM-2P switching relay with my L8124A aquastat? If so how? The ARM-2P does not have ZC/ZR terminals, only X1/X1 and X2/X2.
Thanks.

Nick , do you have

the 8124 controlling a circulator from terminal C1 ? If it doesn't , you can connect the T-T of the aquastat to the X-X terminals of the Argo . I'm not sure if it's X1 or X2 - whichever end switch makes on a call for heat in the Argo .

Thanks for the quick reply.
Yes, my aquastat L8124A controls my first zone circulator. I'm adding two more circulator zones and I'm trying to figure out if the ARGO ARM-2P I bought will work. The ARGO technical support told me I should return it and get a three zone ARM-3P which has the ZC/ZR terminals. (The ARM-2P doesn't have ZC/ZR, only X2/X2 isolated switch.) The only thing is I don't need three zones on the -3P, just two.

sounds like you need

to control 3 zones..

"...my aquastat L8124A controls my first zone circulator. I'm adding two more circulator zones... "

2+1=3

Better to control all 3 from a central control point, and have the ARM 3P control the boiler, than to have to spaghetti wire 2 systems.

That's

what I'd do too.
