My home thermostat has relays to switch the heat and A/C. They are very loud. Is there any reason why this couldn't have used MOSFETs for the switching?
Some EDM sound-damping inside the enclosure might work.I can hear them click from anywhere in the house, even the basement.
Sure but it's not a trivial matter.True, but I'l still like to either replace the relays or build my own thermostat using SSR's.
