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.

Skipping an event
Using figure 24 as an example, if you wanted the same settings to be in
effect from 6:00 AM until 5:00 PM, rather than change all the 8:00 AM settings to match the 6:00 AM settings, simply press and hold the 8:00 AM
button until all the settings and the boxes grey out". Effectively, this
changes the thermostat from a 4−event−per−day to a 3−event−per−day
thermostat.
To turn the event back on, press and hold the same time button until the
boxes and settings are solid again.
After making any changes to this screen, a save button will appear.
