Honeywell Home RCHT9610WFSW2003 T9 WiFi Smart Thermostat with Smart Room Sensor
Want to cut down on bills and energy waste? The ENERGY STAR certified T9 Smart Thermostat has your back. Control your home's climate from your couch or halfway around the world with your phone. Or, better yet, let it do the thinking for you with Auto Home/Away Scheduling—because who remembers to adjust the thermostat before leaving? Plus, if you're eligible, jump into your local Utility's "DEMAND RESPONSE PROGRAM" for some sweet rewards.
Ever tossed and turned because your room was too hot or cold? The T9 lets you dial in the perfect sleep temperature for your bedroom (or any room, really). And with Smart Room Sensors, it knows when you're there and adjusts accordingly—no more heating an empty room.
Worried about signal strength? Don't be. The T9 boasts a sensor range that can stretch up to 200 ft (though your home's layout might play a role here).
Got more than one room? The T9's got you covered, balancing comfort across your entire home like a pro.
Control freaks, rejoice! Whether you're team Alexa, Google Assistant, or Apple HomeKit, the T9 plays nice with all of them. Or just use the Resideo app for direct control.
Not a fan of complicated setups? The T9's DIY installation is a breeze, thanks to step-by-step guidance and a power adapter that sidesteps the need for a C-wire (though you'll need one for some systems).
Heads up: While the T9 works with most heating and cooling setups, it's not buddies with electric baseboard heat (120-240V). And yeah, a C-Wire is a must in certain cases.
