							Service = HEAT PUMP / AC STATUS
STAGE: (HEAT / COOL):
OFF, LOW, HIGH
Displays stage of heating or cooling that the heat pump/AC is
delivering.
DEFROST:
NO, YES
Displays status of defrost mode if heat pump.
AIRFLOW CFM:
Indoor unit cfm measurement.
BLOWER RPM:
RPM feedback from indoor motor.
COIL TEMP:
Degrees F.
Temperature of the outdoor unit coil (only available on 2-speed
communicating outdoor units).
STATIC PRESS:
Static pressure of indoor unit.
Service = LAST 10 SYSTEM FAULTS
This screen will show last 10 faults that occurred throughout the
system. Each fault has the time and date of incident recorded.
Service technician should enter current date in″TODAY’S
DATE″menu section before checking and logging the last 10
system faults. Each fault has a two-letter acronym preceding the
fault name to identify which piece of equipment generated the
fault.
HP = heat pump
AC = air conditioner
FN = furnace
FC = fan coil.
Service = RUN / FAULT HISTORY
The indoor unit and outdoor unit (if communicating) has the
following histories:
NOTE:For Critical Fault Screens, see Trouble Shooting section
in this document.
Resettable Faults:
Fault counters for each piece of equipment that can be reset.
Cycle Counters:
Number of heat/cool/power cycles the unit has performed.
Run Times:
Lifetime hours of operation in heating, cooling, and how long
the unit has been powered.
Service = TODAY’S DATE
This menu item allows the installer to enter the current date. It
is used for time/date stamping of system faults. This should be
entered every time prior to viewing″LAST 10 SYSTEM
FAULTS″section.
Service = MODEL / SERIAL NUMBERS
If available, this menu item allows the installer to view the
model number and serial number of all communicating pieces
of equipment in the system.
Service = SERVICE PHONE NUMBER
This menu item allows the installer to enter a name and phone
number that the homeowner can call for future service of the
system. This name and phone number will appear to the home-
owner whenever a service reminder pop-up message is displayed
(i.e. Change Filter, etc.)
To edit:Use Temp +/- button to move cursor left and right.
Use Time +/- button to select numbers and letters.
Use Scroll button to move up and down between NAME and
NUMBER.
OPERATIONAL INFORMATION
Continuous Fan Operation
Pressing FAN button will scroll through the following:
AUTO = No fan operation except during equipment operation.
LOW = Approximately 50% of High Speed operation.
MED = The difference between High and Low speed operation.
HIGH = Highest of either High Heating or High Cooling CFM.
Five-Minute Compressor Timeguard
This timer prevents compressor from starting unless it has been off
for at least 5 minutes. It can be defeated by simultaneously
pressing the Fan and Temp + buttons.
Emergency Heat (for heat pump applications)
To activate Emergency Heat, youmustpress and hold the HEAT
button for 3 seconds to activate.
Keypad Lockout
Keypad can be locked by pressing Fan and Humidity/OAT buttons
at the same time for 3 seconds. When keys are locked, a lock
symbol will appear in the upper left corner of screen. Follow same
procedure to unlock keypad.
Heat and Cool LED
The Heat and Cool LEDs will pulsate during actual equipment
operation.
Equipment Cycle Timer (adjustable 4-6 cycles per hour)
This timer prevents the start of a heating or cooling cycle until 15
(or 10) minutes after the last start of the same cycle. Its function is
to assure that the equipment is not cycled more than the selected
times per hour. This timer is adjustable from 4 to 6 cycles per hour.
This timer is defeated for one cycle when the desired temperature
is manually changed. It can also be defeated for one cycle by
simultaneously pressing the Fan and Temp + buttons.
Ten-Minute Staging Timer
In multistage heating or cooling, this timer prevents any higher
stage from turning on until the preceding stage has been on for 10
minutes. This timer is defeated if temperature error is greater than
5°F (usually due to a large change in desired temperature).
Three-Minute Minimum On Time
In normal operation, when a stage turns on, it will remain on for a
minimum of three minutes. If the set point is changed, this timer is
automatically cancelled, allowing the equipment to turn off imme-
diately when the demand is removed.
Heat/Cool Set points (Desired Temperatures)
A minimum difference of 2°(default) is enforced between heating
and cooling desired temperatures. This is done by allowing one
setting to″push″the other to maintain this difference. This
difference is adjustable via the Install/Service menu under Ther-
mostat Setup.
Auto Changeover
When Auto mode is enabled (factory default) a change from heat
to cool (or vice versa) will not occur until an opposite mode
demand has existed for 30 minutes. If the set point is changed, the
30-minute requirement is defeated. This Auto Changeover time is
adjustable via the Install/Service menu under Thermostat Setup.
Range=5-120min.
Smart Recovery
11 
						

							With Smart Recovery selected (factory default), transition out of
setback begins a fixed time period before selected recovery time
and gradually adjusts room temperature so desired temperature
will be achieved at selected recovery time. The fixed time period
is 1.5 hours. It operates in both heating and cooling. This only
applies to programmable operation.
Media Filter
If amediafilter is installed in the indoor unit, the system will
perform a static pressure check of the system whenever power is
applied to the system, or the system is transitioned from Off to
Cool or Heat modes. The blower will run at a medium airflow for
one minute.
TrueSense™Dirty Filter Detection
When MEDIA or MEDIA+EAC is installed, a static pressure
check will automatically be performed every 24 hours at 1:00PM
to monitor filter accumulation.
TROUBLESHOOTING
Infinity Control™does not power up.
1. Recheck wiring to ABCD on all devices.
2. Make sure all colors match for every terminal.
3. Make sure power is applied to the indoor unit, and the amber
LED is lit on indoor control circuit board.
4. Check for 24VAC between the C and D terminals at Infinity
Control™terminal connector.
5. Check fuse on indoor unit’s circuit board.
Display says″Indoor Unit Not Found″
1. Recheck wiring to ABCD on all devices.
2. Make sure all colors match for every terminal.
3. Press left-side button to try again.
4. If display still reads″Indoor Unit Not Found″, disconnectall
devices from ABCD and connect User Interface directly to
indoor unit.
Display says″Outdoor Unit Not Found″, and I have a two-
speed communicating outdoor unit:
1. Recheck wiring to ABCD connector on outdoor unit.
2. Make sure all colors match for every terminal.
3. Check for 24VAC between the C and D terminal connector.
I made a mistake on the start-up screens, and hit the right-side
button to get to the run mode. How do I get back to start-up?
1. Press the ADVANCED button for at least 10 seconds.
2. Install/Service menu will appear.
3. Scroll down to the INSTALL selection.
4. Press the right-side button; the screen will prompt you to press
the right side again to re-install the system.
