These functions work with the white square controller that comes with the EVI (HVAC) heat pumps and the Pool/Spa heat pumps. If you have a gray rectangle controller... most (but not all) of this will apply.

Advanced Functions

View the Running Parameters

During normal operation you can view the running parameters of several functions. You cannot change these parameters; they just tell you how the heat pump is performing.

  • When you are completed, press the power button one time to exit this mode. 

Error Messages

When the heat pump encounters an error, it will display the error code on the Screen. The errors are listed in the manual of your Heat Pump with a brief description of what they mean. For more details about the error, you can visit the “Arctic Heat Pumps” website and ask the chat bot how to fix it. 

Hidden Error Messages

The heat pump also includes several hidden error messages. These normally do not stop the heat pump from working, but they will indicate a potential problem down the road. These are like a “check engine light” in a car. 

  • If the controller is locked, you must unlock it prior to viewing the hidden error messages. To unlock the controller Press and Hold the Power Button for 5 seconds.
  • Press the “Clock” and “Function” buttons (the two buttons on the left) at the same time to view the hidden error messages. 

Note: These can only be checked when the unit is running and not displaying any standard error codes at the time.
