What does Elitech E1 mean?

E1 means the controller has lost a valid reading from the cabinet temperature sensor (the main room probe). On Elitech controllers such as the ETC-974A and ECS-974neo the display shows E1 whenever the cabinet sensor fails.

What does Elitech E2 mean?

E2 indicates the evaporator temperature sensor has failed. The Elitech manual lists E2 as evaporator sensor fault and shows it when the evaporator probe fails.

What does Elitech AH1 mean?

AH1 is the high cabinet temperature alarm. The Elitech manual states it is triggered when cabinet temperature exceeds the set-point (SEt) plus the High Alarm differential (HAL) and the temperature alarm delay has elapsed; the controller then displays AH1.
