Navien CH-240 ASME Outdoor reset Connection
HI, I have a Navien CH-240 ASME and I'm trying to install the outdoor temp sensor. I bought the sensor pt. # NASS9EXOS001 but it didn't come with a cable.I thought I could connect thermostat wire right to the circuit board, but there is a small 2 pin connector on the board. Has anyone installed one of these. Any advice would be greatly appreciated... Thanks.. Victor in Swansea, Ma.
