RUUD UEAB 1413 J HEATER BLOWS AIR AT ROOM TEMP. I have 2 units, one upstairs, one down. THe downstairs unit blows hot air. The upstairs unit blows cool air when the heat is on. 18 degrees outside.

SOURCE: dehumidify mode also cools

Some units do cool/dehumidify only im afraid why cant you let the unit dump its hot air into the room then it wont heat or cool the room?

I f it is fan that has more then one speed if you run it all the time,it may
not be on high sample : low fan speed runs all the time
med fan speed for heat
high fan speed is usually for air conditioning so if everything is good then it maybe the relay.

The thermostat would need to be insulated better from the air that is surrounding it. Im assuming that the thermostat is located on the wall unit where it blows out the air. This could mean that it is actually reading more from the outside temp, than whats inside the house. Another thing to consider is the location of the thermostat, even it being close to anything in the house that produces some kind of heat will effect the condition of the air. If anything, its the manufacturers mistake if it was properly installed in the first place and if defective, they should replace it. hope this helps.
