    American Standard Hydro Air

    Installing a American Standard Communicating Air Handler with external hydro heating coil.. To start the circulator off a Taco switching relay and not to have back feed on the air handler is there a control for this operation.  Two stage cooling and single heating

    Relay

    Is the call for heat though a control board in the air handler ? I would check to see if it's a dry contact . I would assume it is but I dont have the paper work .If itis dry just go to TT in the circ relay . If not use a cheap RIB relay
    I have enough experience to know , that I dont know it all

    Will a rib relay tw240 series with an current sensor around the w1 terminal work?
