can I use a Thermidistat with my unit?
I've got a carrier FV4BNF005 air handler which says its variable speed and the docs say you can use it with a Thermidistat. I've paired this with a 24HCA448A003 4 ton HP. Can I use a Thermidistat, or do you need a variable compressor as well?
Right now, I've just got a honeywell thermostat as the controller, and I'm wondering if I'm missing out on someting.
