Title: Replace old with smart thermostat
Post by: topaz318 on November 17, 2021, 12:06:37 PM
Hello, just bought a new house which has old CM260 thermostats with zoned HVAC which is new to me as follows - First Master zone with 2 sub-zones Second Master zone
Questions - Should I get 4 smart thermostats? Also, do I need a C wire adapter for all 4?
