What the Display Codes Indicates, and How to Respond to Them
EE Indicates the control’s operating pressure range has been changed, both P6 jumpers are in the Installed
position, or a program failure has occurred. Ensure that the P6 jumpers are positioned for the correct pressure
range. (See Table 2.) Press the Menu button twice to reset the control for a new operating pressure range.
If EE is still displayed, a program failure has occurred and the control must be replaced.
A x A flashing A x alternating with a flashing XXX
psi
indicates the control is in an Anti-Short Cycle delay sequence.
The x in A x indicates the minutes of remaining Anti-Short Cycle delay. 0 minutes indicates the control is in the
final minute of the delay. XXX
psi
indicates the sensed pressure value in this display.
ci1 Indicates that the primary cut-in setpoint may be changed by pressing the Menu button once to display the
current ci1 value (XXX
psi
). Then press the Up or Down buttons to change the current ci1 value.
co1 Indicates that the primary cutout setpoint may be changed by pressing the Menu button once to display the
current co1 value XXX
psi
). Then press the Up or Down buttons to change the current co1 value.
ci2 Indicates that the secondary cut-in setpoint may be changed by pressing the Menu button once to display the
current ci2 value (XXX
psi
). Then press the Up or Down buttons to change the current ci2 value.
co2 Indicates that the secondary cutout setpoint may be changed by pressing the Menu button once to display the
current co2 value (XXX
psi
). Then press the Up or Down buttons to change the current co2 value.
ASd Indicates that the Anti-short Cycle delay may be changed by pressing the Menu button once to display the
current Anti-short Cycle delay time in minutes. Then press the Up or Down buttons to change the current
Anti-short Cycle delay to any whole-minute value between 0 and 9 minutes.
XXX
psi Indicates the current pressure setpoint value (in psi) for either ci1, co1, ci2, or co2, depending on the previously
displayed Display Code. Press the Up or Down buttons to change the setpoint value.
1
Err
Indicates that an invalid pressure setpoint has been entered, and the resulting setpoint differential is less than
the required minimum setpoint differential. Press the Up or Down buttons to create a setpoint differential that is
greater than or equal to the required minimum differential for the selected operating pressure range.
1. The Err display code does not flash.
