Cannot get the outside temp to respond on a WS9047U-IT

my unit tells me to insert fresh batteries into the outside sending unit first. then insert new batteries into the inside receiving unit. after the outside temperature shows up, then can reset my inside unit's time, choose F or C and
switch channels. please try changing channels if your
outside temp doesn't show. you can do both units in the house then put one outside after they work properly.

I am guessing this is an outside weather temperature thing? Have you checked the batteries of the outside probe? Made sure the "channel" is on the right setting etc?

Run self test on heater control head. With the key press off and floor buttons at the same time for 2seconds then release and press auto button for a second.this will put system into self test.if no code all the blend door actuators are ok and I would think vacuum leak from main vacuum, black line going through fire

Hard to say.
Under normal conditions, vent temp should be about 20 or 25 degrees less than outside air temp.
So if outside air temp is 90 degrees and the engine is at idle speed, vent temp would be around 65 or 70. On the road the vent temp could be less than 60 degrees.
If outside air temp is 70 degrees vent temp will be around 40 - 50.

Check the inside and outside low voltage wiring connecting the control panel. Take inside panel to the outside panel and hook up. You might have a bad wire.

well with 62 outside temp and then maybe a little solar gain and body heat you very well could be 5 degrees warmer then outside
