I have a Model 02059M base unit with 3 Model 06044 temp. sensor units. I have fo\ound there is a great degree of diffference in one of the remote sensor units. If I place them all in the same location, one of the units reads 4 deg. F high than the others. I am will to see a one deg. variance, but 4 deg. seems like a lot to me. Any one else see this large variable?
