Honeywell’s Total Connect Comfort is the perfect solution if you travel frequently, own a vacation home, a business or manage an

Investment property or if you are simply looking for peace of mind.

This thermostat works with common 24 volt systems such as forced air, hydronic, heat pump, oil, gas, and electric. It will not work with millivolt systems, such as a gas fireplace, or with 120/240 volt systems such as baseboard electric heat.

This thermostat contains a Lithium battery which may contain Perchlorate material. Perchlorate Material—special handling may apply.

See www.dtsc.ca.gov/hazardouswaste/perchlorate

MERCURY NOTICE: Do not place your old thermostat in the trash if it contains mercury in a sealed tube. Contact the Thermostat Recycling Corporation at www. thermostat-recycle.org or 1-800-238-8192 for information on how and where to properly and safely dispose of your old thermostat.

NOTICE: To avoid possible compressor damage, do not run air conditioner if the outside temperature drops below 50°F (10°C).

Installing your thermostat

Important! The Wi-Fi thermostat requires a C wire to operate. The C, or common, wire brings 24 VAC power to the thermostat. Many older mechanical or battery operated thermostats do not require a C wire. If you don’t have a C wire, try:

Looking for an unused wire that is pushed into the wall. Connect that wire to C and check that it is connected to the 24 VAC common at your heating/cooling system. Check the video section at wifithermostat.com

Note: Not all heating/cooling systems label the 24 VAC common C. Check your system manual or contact the manufacturer to find out which terminal is the 24 VAC common.

View the Alternate Wiring videos at wifithermostat.com/videos

Important! Heating/cooling system type must be set so that your thermostat operates properly and does not damage your system.

12a If you have a traditional system (natural gas forced air with A/C), your hermostat is set up by default to control this system.

12b If your system is:

Conventional multistage heat and cool

Any type of heat pump

Hydronic

Other

If you are not sure of your heating/cooling system type or have other questions, go to wifithermostat.com

You MUST change the system type by setting system function 0170. See page 54 to match your thermostat to your system type.
