I'm installing a HAI RC-80 thermostat with evental plans to install a smart home controller. I want to make my runs now before the walls close up. I'm being told 22 gauge 5-wire CAT 5 for the run to the furnance(1-stage Lennox) and cooling and 22 gauge, 4-wire CAT 5 to the controller. Would this be correct in your opinion?
