To connect to Wi-Fi, ensure your smartphone is connected to a 2.4 GHz Wi-Fi signal, then press and hold the indoor temperature in the center of the thermostat screen for 5 seconds until the screen changes. Download the Lyric app from the App Store or Google Play, then open the app — your thermostat should appear under 'Thermostat Found.' Tap 'SET UP NOW' to continue, or tap 'INSTALL A DEVICE' and follow the prompts if it doesn't appear automatically. Note that the thermostat only supports 2.4 GHz Wi-Fi and will not connect to a 5.0 GHz network. (Page 10)
What does it mean when 'Cool On' or 'Heat On' is flashing on the screen?
A flashing 'Cool On' or 'Heat On' message means the built-in compressor protection feature is engaged. The thermostat forces the compressor to wait a few minutes before restarting to prevent damage to the heating or cooling system. This message is also displayed during a startup delay if AC power loss occurs. Once the wait period is over, the compressor will turn back on automatically. (Page 9)
What are the alert codes and what do they mean?
The thermostat displays 3-digit alert codes when an issue is detected. For example, code 164 means the heat pump needs service, code 173 indicates a thermostat temperature sensor error, and code 399 means the internet connection has been lost. To view an active alert, touch Menu on the home screen, then touch Select to see the alert code and a scrolling description of the required action. (Pages 27–28)
How do I reset the thermostat's schedule back to the default settings?
To reset to the default Monday–Friday, Saturday–Sunday schedule, touch Menu on the thermostat screen, then use the arrows to navigate to RESET and touch Select. Use the arrows to select SCHEDULE and touch Select, then touch Yes to confirm. This will revert the schedule to the factory default without affecting other settings. (Page 18)
How do I safely clean the thermostat screen?
Use the Clean Screen option to disable the touchscreen for 30 seconds while you clean it. To activate it, touch Menu, navigate to CLEAN SCREEN, and touch Select — a countdown timer will display the time remaining until reactivation. To clean, spray water or household cleaner onto a cloth and use the cloth on the screen; avoid abrasive cleaners and do NOT spray liquid directly on the thermostat. (Page 24)
What is Adaptive Intelligent Recovery and how do I enable or disable it?
Adaptive Intelligent Recovery is a feature that learns how long your system takes to reach the desired temperature and turns on heating or cooling equipment at the right time so your home is comfortable when you expect it to be. This feature is enabled by default. To disable it, touch Menu, navigate to RECOVERY, select RECOVERY OFF, and touch Done to confirm. (Page 22)

Note: This ISU may not be available at all on some models. 300 Auto Changeover On, Off OFF: The user must select heating or cooling as needed to maintain the desired indoor temperature. ON (Automatic): On (enabled) Allows user to select Auto Changeover as one of the system modes from the home screen. In auto mode, the thermostat can control either heating or cooling to maintain the desired indoor temperature. 303 Auto Differential 0 °F to 5 °F or 0.0 °C to 2.5 °C Differential is the minimum number of degrees allowed between the heat and cool setpoints when the thermo stat is in auto-changeover. Differential is NOT deadband. The deadband temperature between when heating (or cooling) cycles on and cycles off to maintain setpoint is not adjustable. Honeywell uses an algorithm that fixes deadband at 0 °F. This algorithm is more advanced than on previous thermostats. 305 High Cool Stage Finish Yes, No This ISU is only displayed when the thermostat is set to 2 cool stages. When set to YES, this feature keeps the higher stage of the cooling equipment running until the desired setpoint is reached. 306 High Heat Stage Finish Yes, No This ISU is only displayed when the thermostat is set to 2 or more heat stages. When set to YES, this feature keeps the higher stage of the heating equipment running until the desired setpoint is reached. 340 Aux Heat Droop 0 = Comfort; 2 °F to 15 °F from setpoint (in 1 °F incre ments) or 1.0 °C to 7.5 °C from setpoint (in 0.5 °C increments) Aux heat droop can be set on heat pump systems with an auxiliary heat stage. The Comfort setting is NOT available for Dual Fuel systems. Default setting is 0 °F (Comfort) for Electric while 2 °F for Gas/Oil. The indoor temperature must drop to the selected droop setting before the thermostat will turn Aux Heat on. For example, if Aux Heat is set to 2 °F (1.0 °C), the indoor temperature must be 2 ° F (1.0 ° C) away from the setpoint before Aux Heat turns on. When set to Comfort, the thermostat will use Aux Heat as needed to keep the indoor tem perature within 1 °F (0.5 ° C) degree of the setpoint. 350 Up Stage Timer Aux Heat Off, 30, 45, 60, 75, 90 minutes 2, 3, 4, 5, 6, 8, 10, 12, 14, 16 hours The Auxiliary Heat Upstage Timer starts when the highest stage of the previous heating equipment type turns on. Auxiliary heat will be used (if needed) when the timer expires. This ISU is only displayed when ISU 340 (AUX Heat Droop) is set to 2 °F or higher. 355 Balance Point (Compressor Lockout) Off, 5 °F to 60 °F (in 5 °F increments) or -15.0 °C to 15.5 °C (in 2.5 °C or 3.0 °C increments) Compressor Lockout requires an outdoor temperature. Set Compressor Lockout to the temperature below which it is inefficient to run the heat pump. When outside temperature is below this setting, thermostat will lockout heat pump and run Aux Heat only. This ISU is only displayed if ISU 130 = Wired or Internet, ISU 200 is set to Heat Pump, ISU 221 Aux/E stages = 1, AND ISU 260 is set to Thermostat. We recommend using a wired remote sensor as an outdoor temperature source. Default is 40 °F if ISU 205 Heating Equipment is Air to Air Heat Pump and ISU 255 Aux Heat Type is Gas/Oil. Default is Off if ISU 205 Heating Equipment is Air to Air Heat Pump and ISU 255 Aux Heat Type is Electric. Default is Off if ISU 205 Heating Equipment is Geothermal.

ISU Name ISU Options (defaults in bold) Notes 1000 Vent Type None, ERV/HRV, Passive, Fresh Air Damper None: The thermostat does not control ventilation. ERV/HRV: The thermostat controls an Energy Recovery Ventilator or Heat Recovery Ventilator for ventila tion. Passive (Fan Only): The thermostat turns on the fan for ventilation. When set to passive fan, the thermo stat does not control a damper or ventilator. The passive ventilation/passive fan setting only runs the indoor blower fan. This setting does not open a damper or run a ventilator. To use this setting for ventilation, the home would need to be set-up with a pipe from outdoors into the return duct that is either permanently open or has a damper that automatically opens whenever the blower fan is on. Note: Some models only offer the passive fan setting. 1005 Vent Method ASHRAE 2010, ASHRAE 2013, Percent On Time Note: Options of this ISU may vary depending on the model of the thermostat. 1006 Vent Fan Control Thermostat, Equipment Thermostat: The thermostat turns on the ventilation and the fan when ventilation is needed. Equipment: Ventilation equipment controls the blower fan. 1007 Bedrooms 1 - 6 (2) This ISU is only displayed when ISU 1005 Ventilation Method is set to ASHRAE 2010 or 2013. 1008 Home Size 1000 - 5000 Sq. Ft. (1000 Sq. Ft.) This ISU is only displayed when ISU 1005 Ventilation Method is set to ASHRAE 2010 or 2013. 1009 Vent Rate 30 - 350CFM (in 5CFM increments) (150CFM) This ISU is only displayed when ISU 1005 Ventilation Method is set to ASHRAE 2010 or 2013. 1011 Vent Percent On Time 10% - 100% (30%) The thermostat operates ventilation equipment based on a percentage entered in the installer setup (ISU 1012). For example, if Percent on Time is set to 50%, the ventilation equipment will run at random times dur ing a 1 hour period until it reaches a 50% run time (approximately 30 minutes). This ISU is only displayed if ISU 1005 is set to Percent On Time. 1012 Vent Priority Lockouts, ASHRAE Lockouts are Priority: The thermostat places a priority on lockouts versus the ASHRAE ventilation standard. The thermostat will not run ventilation during the following lockout conditions (if configured), unless you manually call for ventilation: Lockout Ventilation during Outdoor Conditions (ISU 1013, 1014 and 1015). Lockout Ventilation during “Sleep” program periods. Note: This option is set by the user on the Ventilation screen in the Menu. ASHRAE is Priority: ASHRAE requires additional ventilation following a long off cycle. The thermostat meets the ASHRAE ventilation standard by running additional ventilation when outdoor conditions are favor able. If ASHRAE cannot be met when outdoor conditions are favorable, the thermostat will override the outdoor lockouts and run ventilation. When using this option, it is recommended that you increase the rate (CFM) of the ventilation equipment to meet the ASHRAE ventilation standard in a shorter run time. The ability to lockout ventilation during the “Sleep” is not an option when you select ASHRAE is Priority. 1013 Low Outdoor Temp Vent Lockout Off, -20 °F to -40 °F (in 5 °F increments) or -28.0 °C to -4.0 °C (in 2.0 °C increments) ISU 130 must be set to Wired or Internet.
