    T775 heads up

    I highly recommend bench testing any T775's before you leave the supply house. We've had a rash of them that have bad modulating outputs, sending out a constant 15-16vdc even when the display shows anywhere from 0-10vdc. We are waiting on a response from Honeywell.

    Does Resido also make those?
    If you were a real tech, you'd solder a relay on that board and call it good to go.

    I do a triple evac with nitro to remove non condensables.

    I use 56% silver on everything except steel.

    Did you really need the " If you were a real tech " ??

    EDIT The new software outputs default to 4-20 The old software defaulted to 0-10. The programming needs to be changed.
