ERROR CODES:

11. Troubleshooting Guide
Display Likely Causes Other Possible Causes        
Controller   display  remains blank after applying power. ·     Unit power not properly applied – check
·     Power  cable  harness  not  plugged  in properly or securely into the back of the controller - check connections.		 ·     Power  cable  miswired  –  inspect cable; replace if needed.
·     Electrical  assembly  miswired   – trace wiring diagrams.		        
Controller                displays correctly,    but    the    green compressor  light  is  off  and the    compressor    is    not running. ·     Jumper cable not plugged in properly or securely into the back of the controller – check connections
·     Controller  is  currently  above  the  cut-in setting   –   check   cut-in   and   cut-out settings		 ·     Jumper cable miswired – inspect cable; replace if needed.        
Controller                displays correctly,        the        green compressor light is on, and the    compressor    is    not running ·     Power  cable  harness  not  plugged  in properly or securely into the back of the controller – check connections. ·     Power   cable   not   wired   to   the contactor or compressor correctly
– check wiring.
·     Power  cable  miswired  –  inspect cable; replace if needed.		        
Controller  flashes  “135”  or “P1” ·     Current   system   pressure   above   135 PSIG – wait for system to pull down.
·     Green  harness  not  plugged  in  properly or securely into the back of the controller
– check connections.
·     Cable  not  connected  properly  with  the pressure       transducer       –       check connections.
·     Compressor  is  not  running  to pulldown suction pressure below 135 PSIG.		 ·     Transducer    cable   miswired    – inspect cable; replace if needed.
·     Damaged    transducer–    inspect transducer    DC    voltage    value against   table   in   Section   10.; replace if needed.
·     After 15 minutes Standby system pressure is above 135 PSIG and compressor   is   not   running   to pulldown pressure  a  P1 alarm  is
shown.		        
Controller flashes “P2” on a unit with fan cycling ·     Green  harness  not  plugged  in  properly or securely into the back of the controller
– check connections.		 ·     Transducer    cable   miswired   – inspect cable; replace if needed.
·     Check    condenser    temperature sensor resistance values against table in Section 9.		        
Controller flashes “P2” on a unit without fan cycling after replacing a controller ·     Controller  not  programmed  properly  – check parameters in Advanced Options Menu. ·     All EUC controller from the factory are factory set controller and need to be program base on the default factory       settings       of       the replacement  controller  found  on the   EUC   back   electrical   box
cover.		        
Troubleshooting Guide (continued)
Display Likely Causes Other Possible Causes          
Controller flashes “P3” on a unit with DLT ·     Jumper cable not plugged in properly or securely into the back of the controller – check connections. ·     Jumper   cable   miswired   – inspect    cable;    replace    if needed.
·     Faulty     DLT     temperature sensor   –   check   discharge line     temperature     sensor resistance    values    against table in Section 9. Or Press the   down   arrow   once   to display          the          actual temperature  reading  of  the DLT sensor.
·     Check     DLT     temperature sensor          location          at compressor  discharge  line. Proper  location  is  6  inches away      from      compressor
discharge line.		          
Controller flashes “P3” on a unit without DLT after      replacing      a controller ·     Controller   not   programmed   properly   –   check parameters in Advanced Options Menu. ·     All  EUC  controller  from  the factory     are     factory     set controller   and  need  to  be program base on the default factory     settings     of     the replacement controller found on  the  EUC  back  electrical
box cover.		          
Fans not running on a fan  cycling  unit  and the  fan  lights  are  not on ·     Mid coil condensing temperature currently below the fan cut-in settings.
·     Condensing   temperature   sensor   not   properly installed – check installation.
·     Fan cycling control are cycle ON and OFF base on the run time settings.
Note:  SF1  value  for  cut-out  temperature  must  be added  deferential  HF1  for  the  cut-in  temperature settings for Fan 1. Apply the same rule to SF2 and HF2
for Fan 2.		 ·     Transducer cable miswired – inspect    cable;    replace    if needed.
·     Faulty temperature  sensor  - check                    condenser temperature                sensor resistance    values    against table in Section 9.		          
Troubleshooting Guide (continued)
Display Likely Causes Other Possible Causes          
Fans not running on a fan  cycling  unit  and the fan lights are on ·     Power cable harness not plugged in properly or securely into the back of the controller – check connections. ·     Power    cable    miswired    – inspect    cable,    replace    if needed.
·     Electrical assembly miswired – trace wiring
diagrams.		          
Controller flashes “HP” at power-up ·     Jumper cable not plugged in properly or securely into the back of the controller – check connections.
·     High-pressure  switch  seeing  above  the  cut-out pressure.
·     If replacing a -00 controller, ensure jumper cable is the latest revision. It should have a blue wire in the harness. See Section 8.5 for more details.		 ·     Jumper   cable   miswired   – inspect    cable;    replace    if needed.
·     Faulty   fixed   Hp   switch   – inspect   switch;   replace   if needed.
·     HP switch settings are: 440 PSI cut-out
325 PSI cut-in.		          
Controller flashes “HP” or “HPL” ·     System operation causing high discharge pressures – check system operations. ·     Bad  high-pressure  switch  – verify system pressure when the pressure switch trips.
·     See Section 7.2 for more
details.		          
Controller        flashes “DLT” or “DLL” ·     System operation causing high discharge line temperatures – check system operations. ·     Faulty temperature sensor - check DLT sensor values against table in Section 9.
·     See Section 7.1 for more details.
·     DLT maximum temperature
settings is 225F.		          
Controller       flashing “HPL” or “DLL” ·     System operation causing high discharge pressures (HPL) or high discharge line temperatures (DLL) repeatedly – check system operations.
·     To clear an HPL or DLL lockout, hold the Start button for 3 seconds 2 consecutive times, or cycle power to the unit. If using the reset button, the alarm condition will have to clear (DLT temperature drops or Hp switch resets) and any minimum off time will need to complete (5
minutes for the fixed Hp switch).		 ·     (HPL) high discharge pressures lock alarm is displayed if 5 repeatedly HP alarms occur within 1 hour.
·     (DLL) high discharge line temperatures lock alarm is displayed if 4 repeatedly HP alarm occur within 1 hour.
