Air Handler Control Button, Display and
Jumpers
Use Figure 19 as reference for jumper settings. If any of the
referenced jumpers are missing, the Air Handler Control
will display Error Code 130 as per Table 13, and the Air
Handler Control will automatically use the factory default
Before changing any clippable links or jumper settings,
make sure the motor has completely stopped. Any
changes will not take place while the motor is running.
IMPORTANT
Push Button
An on-board push button is provided for the purpose of
placing the air handler control in different operation modes
and can be used to recall stored error codes. When button
is pushed and held, air handler control will cycle through
a menu of options depending on current operating mode.
Every three seconds a new menu item will be displayed.
If the button is released while that item is shown on the
display, air handler control will enter displayed operating
mode, or execute defined operation sequence for that
menu option. Once all items on menu have been displayed
the menu resumes from the beginning (if button is still
held).
1. Press the diagnostic push button and hold it to cycle
through a menu of options. Every three seconds a new
menu item will be displayed. Release the button when
the desired mode is displayed.
2. When the solid “E” is displayed, the control enters
the Error Code Recall mode. Error Code Recall mode
menu options: No change (displaying error history)
remains in Error Code Recall mode; solid “≡” exits
Error Code Recall mode; and solid “c” clears the
error history. Must press button while flashing “c” is
displayed to clear error codes.
3. When the solid “-” is displayed, the control enters
the applicable mode. Field configuration mode menu
options: Solid “C” starts pressure switch calibration;
blinking “-” exits current active mode.
Jumpers
Jumpers are used for non-communicating mode only.
1.
Humidification
— Controls the status of H terminal
on the thermostat block. Configurations are as follows:
•
If jumper is installed in SMART Humidification
position (Default), H terminal is active if heat
demand is present and indoor blower is running.
•
If jumper is installed in AUTO Humidification
position, H terminal is energized whenever indoor
blower is running.
2.
Blower Only CFM
— Used to select Indoor blower
CFM for continuous operation.
3.
Heat
— Used to select Indoor blower CFM for electrical
heat by placing the jumper in proper position. Actual
CFM values for different air handler sizes are shown in
Targeted CFM tables starting on Page 25.
4.
Cool
— Used to select cooling indoor blower CFM
by placing the jumper in proper position. Actual CFM
values for different air handler sizes are shown in
Targeted CFM tables starting on Page 25.
5.
Adjust
- Used to select the indoor blower CFM
adjustment value by placing the jumper in appropriate
position.
• If NORM is selected, indoor blower runs at normal
speeds.
• If + is selected, indoor blower runs at approximately
10% higher speed than NORM setting.
• If - is selected, indoor blower runs at approximately
10% lower speed than NORM setting.
If the jumper is missing, the Air Handler Control will
activate the Configuration Jumper is Missing alarm
and will automatically use the default factory setting
in Table 11. See Figure 19 for jumper configurations.
Actual CFM values for different air handler sizes are
shown in Targeted CFM tables starting on Page 25.
6.
Delay
— Indoor blower cooling profile, delay for
cooling and heat pump operations.
• For heat pump heating operation only delay
profiles 1 and 2 are applicable. If profiles 3 or 4
have been selected, heat pump operation will use
profile 1 only.
•
For heat pump cooling operation all 4 profiles are
operational.
If the jumper is missing, the Air Handler Control will
activate the Configuration Jumper is Missing alarm
and will automatically use the default factory setting
in Table 11. See Figure 19 for jumper configurations.

A. When cool or heat demand is initiated, motor ramps up
to 100% and runs at 100% until demand is satisfied.
B. Once demand is met, motor ramps down to stop.
