My TT was not pre-wired for a higher end rooftop unit, so the only wire going up there is the 12 gauge power supply.
I thought about an SSR but wondered about having somewhere to put a big heat sink, or if I would need a big heat sink.
I had though about replacing the ceiling module with one designed for an external thermostat, which breaks out the various functions into something a simple thermostat can control, but by the time I got around to doing that, summer would be over and I'd procrastinate until next year.
