Precise Comfort™ Technology

When the iComfort Wi-Fi® thermostat is used with a Lennox indoor or outdoor unit which includes a compatible communicating control, it becomes part of a Precise Comfort™ system.

 Precise Comfort™ Cooling (XC/XP25) — This feature keeps the room

temperature within 1/2 degree of the desired cooling setpoint. The airflow is adjusted in increments as small as 1% to provide ultimate temperature control.

 Precise Comfort™ Heating (SLP98V) — This feature keeps the room

temperature within 1/2 degree of the desired heating setpoint. The airflow

is adjusted in increments as small as 1% to provide ultimate temperature control.

iComfort Wi-Fi® Thermostat

The communicating iComfort Wi-Fi® thermostat is an electronic 7-day programmable touch-screen thermostat with a color display. It also offers enhanced capabilities which include: humidification measurement and control, dew point adjustment control, dehumidification measurement and control, Humiditrol® Enhanced Dehumidification Accessory (EDA) compatibility, and equipment maintenance reminders. The thermostat's autochangeover mode permits control of heating, cooling, humidification, and dehumidification without user involvement.

The iComfort Wi-Fi® thermostat can connect to the internet using your home's Wi-Fi access point. After online registration has been completed, weather information is automatically sent to the thermostat. You also will have full access to the thermostat from any remote location using an internet connection via computer, smartphone, Android™ device, iPhone® or iPad®.

The thermostat stores system parameters in nonvolatile memory to retain data and settings when electrical power fails or is turned off. The thermostat also includes on‐board help screens.

Indoor Air Quality accessories are supported with time‐based maintenance notifications which remind you when to check or replace media filters, UVC bulbs, humidifier pads and PureAir™ catalytic inserts.

Thermostat Lock-Out

A lock icon at the bottom center of the screen (shown in the picture), indicates the thermostat is either partially or fully locked.

When the thermostat is partially locked, any user can adjust the temperature up or down to hold a setting for a selectable time period. To lock the thermostat, access “Screen lockout” through the FEATURES screen “display settings” described on Page 8.

When the thermostat is fully locked, no one can make any changes to the thermostat's settings. To unlock the thermostat, touch and hold the lock icon for 5 to 6 seconds.

Start -Up

In event of power failure —The thermostat will reboot after power is

restored. When the reboot is complete, the HOME screen will return.

WHAT THE HOME SCREEN TELLS YOU...

After the thermostat and the system have been fully connected and powered on, the thermostat's Home screen is displayed. Figure 1 shows a display and describes what the thermostat is telling you.

When the system mode is set to heat or cool, the system is operating in manual

mode;

When a particular program

has been selected, program name will be displayed on the system mode button (e.g., summer program is on).

OTHER INFORMATION...

The system will run until the indoor temperature is within the range specified by the selected cooling and heating setpoints (70 to 75 degrees in this example).

The “Wi-Fi” button in the bottom left corner provides access to the Wi-Fi setting screen. Wi-Fi with a

beneath it indicates a prior connection to the server has been lost. When the Wi-Fi connection is re-established, the triangle goes away.

Away Mode sets the thermostat for energy-saving system operation while you are gone for an extended period of time. In this mode, the system will only come on if the indoor temperature falls below 62 degrees (for heating), or if the indoor temperature rises above 85 degrees (for cooling).

WHAT YOU CAN DO FROM THE HOME SCREEN...

The Home Screen provides you with convenient

access to adjust heating and cooling setpoints,

as well as humidity levels in your home.

From this screen you may:

- adjust temperature settings

- access menus to change the program mode

- change how the fan operates

- access the “Features screen” (fig. 3) by touching

- access and view active service alerts by touching the

icon

- access help screen by touching the “?” icon

Temperature adjustment and system mode of

operation selection are described fully

beginning on Page 14.

you will be able to set the desired humidity level in your home

even if no physical humidifier or dehumidifier is present.

See Page 17 for details on humidity control.
