icomfort Touch® Thermostat

The communicating icomfort Touch® thermostat is an electronic 7−day universal multi-stage programmable touch screen thermostat with color display. It also offers enhanced capabilities which include humidification measurement and control, dew point adjustment control, dehumidifica-

tion measurement and control, Humiditrol® Enhanced Dehumidification Accessory (EDA) capability, and equipment maintenance reminders. The thermostat’s autochangeover mode permits control of heating, cooling, humidification, and dehumidification without user involvement.

The thermostat stores system parameters in nonvolatile memory (retains data when electrical power fails or is turned off), and includes onboard help screens. The thermostat supports heat pumps or non−heat pump units, with up to 4 stage heat / 2 stage compressor operation. (2 stages of heat pump heating and 2 stages of auxiliary backup heat are provided. Also, 2 stages of emergency heat are provided).

Indoor Air Quality is supported with time-based notification of consumables including media filters, UVC bulbs, humidifier pads, and PureAir catalyst service / replacement.

Thermostat Lock−out

A lock" icon at the bottom center screen (shown in the picture), indicates the thermostat is either partially− or fully− locked. Partially−locked, any user can adjust the temperature up or down to set a hold" for a selectable time.

Fully−locked, no one can make any changes to the thermostat’s settings. To unlock, press and hold the lock" icon for 5 seconds.

To lock the thermostat, access Screen lock−out" through the User Preferences described on Page 6.

After the thermostat and your system are fully connected and powered on, the icomfort Touch Home screen is displayed. Figure 1 shows one of the more basic displays. Note that it’s program is OFF, that the current and heat to" temperatures are the same (system is not running) and there are no alerts.

From this screen you may manually adjust the temperature setting using the up/down arrows, or access the User dashboard" screen (figure 3) by pressing the home screen in the press for more area.

The Home screen shown in figure 2 reflects a more complex display. Note that it’s program is ON, that it is set to either heat or cool as necessary, and that the current" and set " temperatures are different (therefore, the system is running). In the example, notice also that there are service alerts present.
