Hi folks,
I'm not sure this is a good group for this question, but I can't find anyone in alt.hvac who even understands the question:
Does no one make a residential heat pump thermostat that also senses humidity and runs the compressor based on enthalpy, instead of just temperature? Not just a thermostat, but a "heat-index-stat," or "enthalpy-stat." Such a unit would not run the cooling until a higher indoor temperature has been reached when the humidity is low, but at a lower temp when the humidity is high. It would probably look pretty much like a conventional thermostat, but the set point would be in something like heat index degrees.
I'm not trying to control humidity and temperature separately. I've had people come up with ideas about connecting a humidistat with a thermostat. That's not the way to go. What I'm looking for senses temp and moisture, and decides when to run the cooling as a function of both. Enthalpy. I've found devices called "thermidistats" by Bryant and Carrier. Couldn't find a good writeup though, and they appeared to be just that. Mostly marketing drivel. Don't want one that senses outside humidity. It must sense indoor humidity to respond to high people load, or other sources of indoor humidity.
Ought to be one.
Thanks.
