    354 no longer in production

    You are seeing 1/2 of a 24 volt signal, I suspect a wiring issue (loose missing neutral) and if the onboard relay of the 354 were bad, you could verify that with a continuity test.

    It's not so much a case of "You got what you paid for", as it is a matter of "You DIDN'T get what you DIDN'T pay for, and you're NOT going to get what you thought you were in the way of comfort". Borrowed from Heatboy.
