    Lennox thermostat 51m33
    I currently have a lennox 51m33 thermostat controlling my heat and ac. I purchased a honeywell dehumidstat h46c to wire parallel with the ac. I've jumped out y1 & o, and y1 & g, but not o & g at the same time. With no results. Are these the wrong terminals , or does the thermostat have to be in place.
