icomfort Wi-Fit Thermostat − Technical Description and Features

The 24VAC icomfort Wi-Fit thermostat (figure 1) is an electronic communicating, color display touchscreen, 7−day programmable thermostat. It stores system parameters and settings in nonvolatile memory (i.e., it retains data when electrical power fails or is turned off). It is designed for 4−wire connection to other communication devices as listed in figure 1.

The icomfort Wi-Fit thermostat can connect to online services via the internet through the homeowner’s Wi−Fi access point. After online registration is completed, the system may then be accessed by the homeowner from anywhere using a remote internet connection via computer or personal communicating device.

Installation and Setup

IMPORTANT! Make sure the router is capable of, and set to operate in wireless network b" mode. Check router utility program or contact service provider for help. When determining the location for the Wi−Fi thermostat, be sure it is in an area near enough to the homeowner’s Wi−Fi router to ensure good communications signal between the thermostat and the router. (Hint: use a smart phone with Wi−Fi to find and determine signal strength.)

Refer to the Quick Start Guide for information about installing the thermostat on a wall and for wiring diagrams for field wiring the thermostat to the system using one of a number of possible configurations. (Wiring diagrams are also shown beginning on Page 59 of this manual.)

NOTE − If electric heat strips are used with an icomfort t−enabled air handler, the strips MUST be configured on the air handler control (AHC) board before beginning the discovery" sequence below.

After all wiring connections are made, apply power to the system. 24VAC will power up the thermostat.

After power is applied to the thermostat for the first time, the processor checks the system for installed communicating devices, the So Simple. So Smart. So Comfortable" screen displays; followed by Use this thermostat?" screen. Touch press here to continue. During the setup process, alerts may pop open to provide the installer with information that affects the setup. Correct the cause of any such alerts prior to continuing setup.

System settings (figure 2) appear first. As you use the up/down arrows to scroll through the settings, the right hand side will show the current value. For example, current value: 9:39 am Aug 15, 2012 shows the current date for Time and Date.

Circulate fan ON time setting

NOTE − If the circulate fan mode is on, a timer is set to measure all the time that the fan is blowing, regardless if it is running to deliver heating or cooling or just for circulation.

Circulate" is enabled on the user’s home screen or system settings page. It keeps air circulating from 15% to 50% percent of time. The following settings approximate how long the fan will run at these typical settings:

15% (9 minutes fan run time per hour)

25% (15 minutes fan run time per hour)

35% (21 minutes fan run time per hour)

45% (27 minutes fan run time per hour).

G71MPP or SLP98 Furnace Note:

If your icomfort Wi-Fit thermostat is being used with a G71MPP or SLP98 furnace and is set to variable−capacity mode of operation (the icomfortt default with these units), the thermostat’s settings for stage timers are ignored (even if shown enabled in the thermostat). The stage timer will be used on the cooling side. The furnace software sets and controls the firing rates. The only other controlling factor is the stage temperature differentials. In Load−Tracking Variable Capacity (default for these furnaces), both stage timers and temperature differentials are ignored.

Page 17

icomfort Wi-Fit 7−Day Programmable Communicating Thermostat

HEAT Setpoint+COOL Setpoint 2

Humidification and Dehumidification Modes how they work

HUMIDIFICATION modes

BASIC & PRECISION These modes allow user control of RH between 15 and 45%. These conditions must be met for either mode to operate:

Shumidification mode has been enabled, and

Sthe unit is in HEAT mode, and

Shumidification demand exists (24V present at H), and

SBASIC mode also requires presence of heating demand [Y for HP heat, or W for gas heat (W may be energized with G de−energized)].

DEW POINT (Available only if Wi−Fi is operational or outdoor sensor is attached)

Basic Dew Point Control Basic Dew Point Control adjustment mode will change the humidification setpoint based on the outdoor temperature and a user−defined dew point adjustment setting.

Precision Dew Point Control Precision Dew Point Control adjustment mode will operate when these conditions are met:

Shumidification mode has been enabled, and

Sthe unit is in HEAT mode, and

Shumidification demand exists (24V present at H).

DEHUMIDIFICATION modes

NOTE − Basic and Precision dehumidification modes are functions of the HVAC system with NO external dehumidification devices installed. Humiditrol and Auxiliary Dehumidifiers do not use these modes.

In BASIC mode, dehumidification occurs if these conditions are met and signals are present at specific terminals:

Sdehumidification has been enabled on installer settings, and

Sthe unit is in COOL mode, and

Sdehumidification demand exists (RH above setpoint), and

Scooling demand exists (Y1 energized).

In PRECISION mode, dehumidification occurs if all BASIC conditions are true, except cooling demand may or may not be present. Also note that:

SMaximum overcool from cooling setpoint is 2ºF.

SDeadband temperature is limited to a minimum of 5ºF (instead of 3ºF in BASIC or DISPLAY ONLY mode) because of 2ºF overcooling.

Humiditrol® or Auxiliary Dehumidifier mode requires:

NOTE − Systems using icomfort tand a dehumidifier − Dehum" jumper on furnace/air handler control does not need to be cut when using with a icomfort Wi-Fi tthermostat.

SWi−Fi is operational or outdoor sensor is installed and set up

Sdehumidification has been enabled on installer settings, and

Sthe unit is in COOL mode, (or if in AUTO, at least one thermostat cooling call made prior to the dehumidification demand), and

Sa dehumidification demand exists (RH above setpoint), and

Soutdoor temp. below 95°F; indoor temp. above 65°F, and

Sfor HUMIDITROL, adjust Humiditrol® comfort parameters as follows:

MAX adj. − Indoor temp > 2°F above heating setpoint

MID adj. − Indoor temp >

MIN adj. − Indoor temp > 2°F below cooling setpoint

Auxiliary Dehumidifier (stand alone dehumidifier)

When this option is selected, dehumidification will be allowed under the following conditions, provided there is NO call for humidification:

SIn the absence of heating or cooling calls, or

SSimultaneous with blower only calls.

If the blower is required to operate while the auxiliary dehumidifier is running, a separate wire must be installed from the auxiliary dehumidifier to the indoor unit’s G thermostat input that will energize G when the auxiliary dehumidifier is running (see wiring diagram on Page 61).

Auxiliary dehumidification is controlled by the thermostat dehumidification demand.

NOTE − Refer to HCWH Dehumidifier Installation Instructions for installation recommendations.

View and clear Installer Alerts

NOTE − Service alerts remind users to service filters, humidifier pad, UV light and PureAirt Air Purification system and are not shown in the installer’s menu.

From the user’s home screen, press and hold the Lennox" logo in the bottom right corner of the thermostat to access the installer program. Press yes when asked if you want to proceed. The installer screen opens at the system and device alerts" screen (figure 24A).

The left side of the "system and device alerts" screen shows a list of each communicating device discovered in the system and check boxes for selecting each device. Or, you may use buttons to the right of the System Devices list to select all (or deselect all). After something has been selected; use view active to list all active alerts for selected devices. If there are no alerts, the display will show There are no new alerts that require service". If there are alerts, these are stored for recall but only one alert will appear in the box at a time (see figure 24B). Use the next button to advance through all the alerts. If only one alert is present, the next button will not appear.

Alerts may pop up on the screen during setup. Details of all active alerts can only be accessed through the installer’s screens. To view all alerts present at any time, press the alerts button. System setup / Diagnostics is complete" (figure 24B) appears; close it and the Select devices to view alerts screen (figure 24A) appears.

The first alert will be displayed in the alert screen (figure 24B), in order of:

1. red alert icon

2. yellow alert icon (service)

A red alert icon identifies a system or device issue that can prevent the system from working properly or at all, and if allowed to run, could cause damage to the system. The issue raised by the alert must be addressed and corrected before clearing the alert!

Press clear (figure 24B) to clear a red alert. The alert will be stored in thecleared alerts" file. If an alert cannot be cleared, revisit the alert issue and make repairs accordingly.
