The 1-Touch Presets allows for an immediate change to the setpoint status. Set the desired temper-
ature for the three status modes (Home, Away & Sleep). The thermostat will remain in the selected
mode until another mode is selected or the program reaches a new schedule period.
Aggressive Recovery: This option disables the 10 minute inhibit anytime the thermostat sees more
than a 2° change (such as moving from one program time frame to another). This applies to heat-
ing & cooling modes.
Heating Aggressive Recovery: This option disables the 10 minute inhibit based on outdoor tem-
perature in heating mode only. The value for outdoor temperature can be set from 0°–70°.
Heating Aggressive Recovery can only be enabled if Aggressive Recovery is disabled.
There is a 10 minute "inhibit" period between first and second stage compressor as well as compres-
sor heating & supplemental strip heat. This 10 minute inhibit period minimizes the cycling of higher
capacity request due to drafts around the thermostat or marginal load conditions.
There are three options when setting the Air Cleaner Mode:
Auto--the air cleaner will run whenever the blower is running.
Quick Clean--the thermostat will energize the air cleaner at 100% output and blower at 100% air flow
for a 3-hour run cycle.
Allergy Clean--the thermostat will energize the air cleaner at 100% output and blower at 100% air
flow for a 24-hour cycle.
System alerts will be indicated on the home screen of the thermostat with two options: "Close" or
"Dealer Contact Information".
•
Selecting "Dealer Contact Information" will display the dealer screen.
•
Selecting the "Close" option will move the alert to the top right corner of the home screen.
Pressing the icon button in the top right corner of the screen will recall the alert to the home
screen.
All alerts will remain until resolved.
Critical Alert – indicates the loss of heating or cooling operation. Only critical alerts will be dis-
played on the home screen. These alerts will flash red when "closed" and moved to the top right
corner of the thermostat.
Major Alerts – indicates the loss of system functionality, but the system is still operational. Major
alerts will be displayed as a solid yellow icon in the upper right corner of the thermostat.
The backlight of the thermostat will increase anytime the screen is pressed (active mode) and dim
after a time period of non-activity (standby mode). This timeout period between active mode and
standby mode can be customized from 5–60 seconds.
Blower on / off profiles can be set independently for heating and cooling modes. There are blower
delays specific for variable speed, non variable speed and hydronic heat applications.
The brightness of the screen can be customized for viewing preferences. Screen brightness can be
set for daytime and nighttime modes.
The Ambient Light Setting icon sets the amount of room light required to shift the display between
daytime and nighttime settings.
The sensors (indoor, remote and outdoor) can be individually calibrated for temperature and humid-
ity. The indoor sensors may be calibrated to plus or minus 5° or 5% humidity in increments of 1 .
The outdoor sensor may be calibrated to plus or minus 10° in 1° increments.
This feature changes the response rate of the thermostat. Selecting a "faster" response rate will
maintain a tighter tolerance of indoor temperatures, but increases the cycling of the system.
Options such as screen brightness, screen savers, background colors, screen calibration and cus-
tomized shortcuts can all be modified to create a personalized home screen.
