Feature Description
1-Touch Presets
The 1-Touch Presets allows for an immediate change to the setpoint status. Set the desired temperature
for the three status modes (Home, Away & Sleep). The control will remain in the selected mode until
another mode is selected or the program reaches a new schedule period.
Aggressive Recovery
Aggressive Recovery : This option disables the 10 minute inhibit anytime the control sees more than
a 2° change (such as moving from one program time frame to another). This applies to heating &
cooling modes.
Heating Aggressive Recovery : This option disables the 10 minute inhibit based on outdoor
temperature 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 compressor
heating & auxiliary heating. This 10 minute inhibit period minimizes the cycling of higher capacity
when the existing capacity is sufficient to meet the demand.
Air Cleaner Mode
There are three options when setting the Air Cleaner Mode:
Auto--the air cleaner will run whenever the blower is running.
Quick Clean--the control will energize the air cleaner at 100% output and blower at 100% air flow for
a 3-hour run cycle.
Allergy Clean--the control will energize the air cleaner at 100% output and blower at 100% air flow for
a 24-hour cycle.
Alert Indication
System alerts will be indicated on the home screen of the control 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 displayed
on the home screen. These alerts will flash red when “closed” and moved to the top right corner of
the control.
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 control.
Blower On / Off Delays
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.
Calibration
The sensors (indoor, remote and outdoor) can be individually calibrated for temperature and humidity.
The
indoor sensors may be calibrated to plus or minus 5° or 5% in increments of 1 . The outdoor
sensor may be calibrated to plus or minus 10° in 1° increments.
Control Response Rate
This feature changes the response rate of the control. Selecting a “faster” response rate will maintain
a tighter tolerance of indoor temperatures, but increases the cycling of the system.
Cycle Rate
The cycle rate affects the cycle time of the system. With a 50% load value, a cycle rate of 3 will allow
the system to run for 10 minutes and be off for 10 minutes; completing 3 cycles in one hour. A cycle
rate of 5 would allow the system to cycle on and off at 6 minute intervals. The higher the cycle rate,
the more often the system turns on and off.
The actual amount of time the system will be “on” or “off” will be reflective in the load value of the home.
Higher load value demands will increase system run time and decrease system off time. Lower load
value demands will decrease system run time and increase system off time.
Dealer Information
Dealer contact information, including name, address, website and multiple phone numbers may be
entered. In addition, a dealer logo (which must be named dealer.jpg) can be uploaded through the
use of an SD card. File size should not exceed 3 MB. With software version 2.1 and above, a Dealer
Code has been added. By simply typing in the dealer’s main phone number, all required fields will be
auto-populated.
