Error Mintemp bed

Hi there I have a Prusa I3 MK 2 upgraded to a MK2.5 that gives me the error "Mintemp bed". only on first startup in the morning. It works perfectly all other times. After switch on in the morning I preheat the machine and wait for the error then I just press reset and preheat again the machine works perfectly all day. Can someone give me an idea of the way to stop this error? Thanks Bob.

Is it cool in the area you are printing. Look at the temp reading and see if it fluctuate quite a bit. Other also could be a bad wire or thermistor going.
