Buderus GB 142 and Argo ARM4P

I've just about completed the instalation of a Buderus GB142-30 and I'm getting ready to wire up the circulators. The Buderus manual wants it's TT conection wired to the XX conections on the switching relay (Argo ARM4P) and I'm not sure if the are refering to the XX conections on the botom row of conections on the Argo. These (XX) are on the same bus with the circulator terminals, but appear to have 24V transformers. ??? Don't want to blow the circuit board on the Buderus.

The Buderi TT's
need to be dry contacts. If you apply voltage from another source to the TT terminals, you will let the smoke out of the controller, and that German smoke is EXPENSIVE.
If there is no way to get a dry contact output out of the Argo zone control, you could set an isolation relay, powered by the Argo, and connect the N.O poles of the relay to the TT on the Buderi.
Without seeing an actual wiring diagram for the Argo, its impossible to say. Sometimes, it as simple as pulling a jumper to make them dry output...

Argo ARM4P
From the Argo Manual: "Seperate X-X (isolated switch) and ZC/ZR relays protect boiler aquastst--can be used either "cold start" or "tankless coil" boiler application. Note that the ZC/ZR terminals are 120VAC connections" Any help?0 -
Check it...
If XX shows no voltage potential between the two terminals when there is a call for heat, then you're OK. If voltage is present, then do not connect directly to the TT on the Buderi.
It would appear that its OK, but better safe than smoked...

BINGO
That did it!! We're up and running and purging air now. Thanks for the help.0
