I would like to use a Tekmar 260 with my existing Taco ZVC 404. Can I get the boiler demand required by the 260 from the ZVC 404.

    Yes JRC

    Use the X-X terminals (Isolated End Switch).

    Wiring as follows:

    24Vac R (+) from a Transformer to one X on 404. Other X on 404 is wired to terminal 1 on 260. Terminal 2 on 260 wires back to C (-) on same transformer.

    Hope this helps. If you need further assistance, please call tekmar tech support at 250-545-7749.

    Regards

    Mike
