HOME AND SYSTEM STATUS ICONS

The following icons are located on the home screen and will appear during applicable operations or tasks.

Icon	Function	Screen Text	Purpose
	Navigation	Menu	Selecting this icon will bring up user and installer menus.
	Function	Away	When the away icon is touched, the system will auto- matically use energy saving settings – heat-to 62 (16.5) and cool-to 85 (29.5). Temperatures can be adjusted by pressing on the available temperature setting (i.e., heat-to or cool-to). To exit away, press the cancel icon. In a zoning system, all zones are set to a single heat-to and cool-too setting. Note that when manually selecting Away from the home screen, the Smart Away feature (if enabled under settings) will be temporally disabled until Away is canceled.
	System Status	Heating	System is heating the home.
	System Status	Cooling	System is cooling the home.
	System Status	Humidifying	If humidification equipment is installed and configured, the system will display this message when adding hu- midity to the air in the home.

Icon	Function	Screen Text	Purpose
	System Status	Dehumidifying	The system can be used in cooling mode to help re- move excessive humidity as determined by the user setting. Go to menu > settings > humidity > and turn on dehumidify. Then adjust the acceptable low and high humidity levels in the home with the dehumidification set-point slider.
	System Status	Defrosting	The system is defrosting the outdoor unit coil (only when required). Heat pump only.
	System Status	Emerg. Heat	All heat pumps operating in northern climates below 35°F (1.6°C) normally need a supplemental heating source. Usually it is in the form of electric heating pro- vided by the indoor unit. Other sources could be gas, oil, or hot-water back-up systems as well. The sup- plemental heat is also referred to as “second-stage”  or “back-up” heating, with “first-stage” being the heat pump only. Emergency heat is when you use your sup- plemental heat (2nd stage) by itself, without the use of your heat pump (1st stage heat). Not available for non- heat pump systems.
	System Status	Aux. Heat	Is only available with heat pump system. If outdoor tem- perature is above the high balance point, only the heat pump will operate – default 50°F (10°C) high. If outdoor temperature is below the low balance point, only aux- iliary heating will operate – default 25°F (-4.0°C) low.   If outdoor temperature is in-between the high and low balance point, both the heat pump and auxiliary heat sources can operate.

Icon	Function	Screen Text	Purpose
	System Status	Will start soon	A five minute safety delay prevents the compressor from operating too soon after shut-down to allow inter- nal pressures to equalize.
	System Status	Ambient lockout	This indicates that either the outdoor temperature is above or below the balance point temperature settings. The low balance point setting prevents heat pump heat- ing below the set point and back up heat will be used. Typically the default is 25°F (-4.0°C), but that setting can be adjusted by your dealer. At 25°F (-4.0°C) or be- low for example, only auxiliary heating (electric or gas) is used. If the high balance point is set to 50°F (10°C ) for exam- ple, which is also adjustable by your dealer, then aux- iliary heat will not be allowed. Only heat pump heating will be used. Anytime the outdoor temperature is below or above the balance point temperature settings, the ambient lockout notice will appear on the home screen.
	Function	Transitioning to next schedule	The system is following an active schedule and is tran- sitioning to the next temperature setting based on a time indicator.

Icon	Function	Screen Text	Purpose
Fan is running			Displayed whenever the system is heating or cooling.
	Function		Fan set to ON
			Fan set to Auto
			Fan set to circulate
	Function	System Under Test	Typically occurs when the system has had a power in- terruption. The thermostat starts to look for the indoor and outdoor controls. Sometimes the outdoor control takes longer to boot up and therefore does not respond to inquiry by the thermostat. Recycle power to system may resolve issue.
	Function	Load shedding, wait time 45 min	Load shedding is where the utility company turns off you outdoor unit in peak times for a specified period of time to help spread the electrical system load for the area. Your system will resume operation in 45 minutes.

Icon	Function	Screen Text	Purpose
	Function	Changing set point range	Temperature is being adjusted. These two symbols to- gether also indicate the mode of operation. As displayed here would indicate heat/cool mode (auto-changeover).
	Function	Turning feels like on	Indicating the system is transitioning to “feels like” mode.
	Function	Schedule hold until next period	The schedule hold screen is displayed after changing the temperatures on the heating or cooling screens while a schedule is running. Preset 1, 2, 4, 8, 24 hours or custom setting (using the Time Tool) sets and hold the temperature for a preset or custom time period until the next time period setting. Cancel schedule hold on Home Screen cancels the held setting.
	Function	Indoor humidity level	This symbol indicates the humidity level in the home. The indicator can display humidity levels from 10 to 100%.

4. Touch join to complete.
5.  If joining the hidden network was successful, the access point name will appear next to wi-fi networks.Whether connecting to a visible or hidden network, if successful, a check mark will appear above both the router and Internet icons.

WIRELESS TERMINOLOGY

• Received Signal Strength Indication (RSSI). This indicates the signal strength of the Wi-Fi router being received by the scanning device (i.e., smart phone). So the higher the RSSI number (or less negative in some devices), the stronger the signal.
• Internet Protocol Address (IP address). This is an address assigned by your home router for each network device (e.g., computer, printer, thermostat).

Connection to Lennox server from your Internet provider may take up to 4-5 minutes depending on your Wi-Fi speed connection speed and how busy the server may be.Locate the thermostat and router away from other devices that could possibility interfere with wireless communications. Some examples of other devices that could interfere are:

• Microwave ovens
• Wireless cameras
• Portable phones and bases
• Baby monitors
• Wireless speakers
• Bluetooth devices
•  Garage door openers

To eliminate a possible source of interference, temporally disable any devices and see if Wi-Fi performance has improved.

DETERMINING WIRELESS CONNECTION SIGNAL STRENGTH
The ideal signal strength range for the thermostat is -1 to -69 Received Signal Strength Indication (RSSI). The signal strength can be viewed from the thermostat interface.

1.  Press NETWORK SETTINGS; This screen shows a graphical view of options representing OPEN and SECURE wireless networks, along with options for adding a network.
2.  Select the access point that has already been established and connected.
3.  When selecting the info icon, a screen will appear which will display an option to forget the network and IP address assigned to the ermostat by your router, sub-net mask, router, DNS and RSSI.
4.  Scroll down to the last entry on this screen. There the Wi-Fi signal strength will be displayed (RSSI). If the RSSI signal strength is anywhere between -9 to -69, then the signal strength is sufficient. If outside the reference range, then either relocate the router closer to the thermostat, add a repeater, or move the thermostat. Adjusting antenna on router may resolve the issue.

CONNECTING TO LENNOX SERVER USING ALTERNATE METHOD
An additional test method is with your cell phone.

1. Enabled the mobile hot spot option on your phone.
   NOTE: Not all data plans allow this function. Check with  your service provider for this option.
2. Connect the thermostat to your hot spot.
3.  Allow up to five minutes for the connection to the Lennox Server.
4.  If you are able to connect then you have verified that the thermostat’s Wi-Fi is functional.
