Mark, Relative humidity is a function of temperature versus humidity. Temperature swings affect humidity and especially, condensation (on plate and strings). Going for reasonably narrow temperature swings and humidity swings is an ideal we should encourage. It is a matter of choosing a comfort versus economy temperature point and then sticking to it. After that controlling the humidity entering the system is important.
