Taco X block

I thought that the taco x block would let you hook a t-stat right to the control on the com/ heat dem. I guess i was wrong and the t-stat needs its own 24v transformer. Anyone have any ideas around this? Thanks Mike

    x block

    It shows that a tstat can be used, tied to the heat demand, but I'm betting it has to be something like a TH1100D Honeywell battery tstat.

    RMB/XPB Demands

    The x block and thr radiant mixing block will both take either a powered or un-powered signal on the demand terminals.
