Honeywell Home T9 Smart Thermostat
The Honeywell Home T9 is built for homes where one thermostat isn't enough. By using Smart Room Sensors with an industry-leading 200-foot range, the T9 can prioritise the temperature of specific rooms—like the bedroom at night or the office during the day—ensuring comfort where you actually are, not just where the thermostat is mounted.
