Automatic Fan Mode
AH-Elite has three automatic fan speeds available: high, medium and low. Automatic Fan Mode allows the AH-Elite to
determine the required fan speed based on temperature differential. This permits a balance between the most efficient
temperature control and slower, quieter fan speeds. To select Automatic Fan Mode, press and release the Fan button until the
LED next to the word "Auto" is lit.
Manual Fan Mode
There are three manual fan speeds available: high, medium and low. Manual Fan Mode allows you to select and maintain a
desired fan speed. When a manual fan speed has been selected, the speed is indicated by one of the 3 LEDs above the AUTO
fan LED. The top LED represents the fastest speed. Press and release the Fan button until the LED next to the desired fan
speed is lit.
Fan-Only Mode
Use the Fan-Only Mode to operate the fan for air circulation when no cooling or heating is desired. From the Off Mode press
and release the Fan button to start fan speed one. Press and release again to select speed two. Press and release a third time
for speed three. Press and release a fourth time to turn off the fan. Turning on the control will revert the fan to the Automatic
Mode or the last selected manual fan setting.
Cycled or Continuous Fan Operation
The fan can be set to run continuously whenever the system is turned on, or it can be set to cycle on and off in conjunction with
the cooling or heating cycles. To change this fan operational setting, press and hold the Fan button for five seconds. If the
pneumonic "CYC" appears, the operational setting has been changed to cycled. If "con" appears, the operational setting has
been changed to continuous.
IMPORTANT
When used with optional electric heat, the fan remains on for four minutes after the heater cycles off even if fan is set
to cycled operation.

Use Program Mode to adjust operating parameters for your particular needs. Program Mode is also used to fine-tune the
system for the most efficient operation within an installation. (Variables such as ducting, sensor location, and system layout
affect system operation.) The control has factory default settings stored in permanent memory that can be recalled. However,
reprogrammed settings can be saved as the new default, thus overwriting the factory defaults. See "P-15: Reset Memorized
Defaults" on page 8 for details.

NTERING
You can only enter Program Mode from the Off Mode. If necessary, press the Power button to enter Off Mode. From the Off
Mode and in the following order, press the Mode, Up, Down and Mode buttons. These buttons must be pressed and released in
the order given. The characters "P 1" appear in the display, which represent the first programming parameter (High Fan Limit).
The "P 1" is followed by the number "95" followed again by the parameter "P 1". "95" represents the setting of the first
programmable parameter (High Fan Limit). The AH-Elite control is now in the Program Mode.

ROGRAM
Press the Power button once to exit Program Mode and return to Off Mode. Or, do not attempt any programming for 50
seconds, then the control exits Program Mode and returns to Off Mode. Any programming changes made while in Program
Mode will be saved and put into operation after exiting Program Mode and returning the control to the On Mode. (If you want the
programming changes to become the new defaults, see "Memorizing New Program Parameters" on page 7.) When you exit
Program Mode the software version number (such as "B23") appears in the display.

HANGING
While in Program Mode, press and release the Mode button to increment from one program parameter to the next until you
reach the desired parameter number. Use the Fan button to move backwards through the parameters. The programmable
parameters range from P-1 through P-26.
When you reach the desired parameter number, use the Up and Down buttons to select the data or set the desired limits for the
parameter being programmed. See Table 2 on page 10 for a list of the parameters, the possible settings for each, and their
factory default settings.
