None of the wiring terminals match anything in the installation manual.Do you have any experience with this? Its a Utica DVB 150.just want to wire lwco& 4 wire honeywell zone valve .Please help .Losing patience
Go to the Uticaboilers.com and find what you need. I don't know why the equipment didn't come with the correct Installation and service manuals. Use a separate t-former to power your HW zone and also the LWCO if you are using a Guard Dawg type. It is critical that you get this right for safety reasons. I'm sure any other company would be glad to give you advise. It is dangerous for us to give advise since we don't even know all that you have on the job sight.
