Re:- condensation problem, there are only two possible measures that can be taken to rectify this, (1) cleaning the dew sensor or (2) disabling it, however neither procedure can be provided as a reply on a web page, this because a JPEG is involved for illustration purposes and which "has" to go to a direct e-mail address, you having chosen to restrict yours. By the way the the No2 method should only be attempted by a technically minded person acquaint at working with small precision pieces of electro-mechanical equipment, plus also being able to solder very finely spaced pin connections.
