Tekmar 262 with De Dietrich Boiler

I am having problems getting my Tekmar 262 to control a De Dietrich 120 boiler. I can hear and verify that the controller is opening and closing the dry contacts of its staging control, which are connected to the TAM terminals of the boiler per MACNA/DeDietrich. The boiler is in Auto mode, but is not taking the firing command from the controller. The pump logic jumper is removed per my supplier.

Any thoughts would be greatly appreciated.

Thenks,

Phil Crome

    I have no idea! It's so bad that I have to admit that I've never even heard of that brand of boiler. Can anyone else help?

    ...would it be something with the controller on the boiler if the tekmar dry-contacts for the boiler stages are operating?

    Just call tekmar at 250-545-7749, should you want to talk about it.
