I've noticed it over the years in various living quarters: an inside A/C temperature setting that's appropriate and comfortable for a given outside temperature is quite unbearable when the outside temperature changes (to result in a different number of A/C runs).
One may think this due to the positioning of the thermostat, but I think the problem is elsewhere — humidity.
As such, I'm curious why is it so common that air conditioning control units only have a thermostat, which so often requires such frequent adjusting when the outside temperature changes? Wouldn't it make more sense to have some sort of a humidistat instead, which would be set at a given point, and would, supposedly, require no further adjustment?
Is there any solution to this effect?
Maybe a control unit that lets you set a cooling value based on humidex, instead of °C / °F? I'd much rather set my HVAC to 27 humidex for the whole cooling season, than keep adjusting it between 21°C and 27°C, up and down, all the time.
