Pump Error Codes
E1 SHORT CYCLE
SITUATION: Defined as a compressor that starts and stops more often (more than
6 times per hour).
E2 KEYBOARD STUCK
ERROR: If a key button is stuck or pressed for 20 seconds or more, the unit
gets stuck. If the key is stuck, it will be ignored until released. If the
“mode” key(button) is stuck, the unit’s function will default to cool mode.
E3 FROST PROBE OPEN:
Normal operation allowed. Change the probe.
E4 FROST PROBE
SHORT: Normal operation allowed. Change the probe.
E5 INDOOR PROBE
OPEN: The control assumes that the indoor ambient temperature is 90 degrees F
and the unit will operate. Change the probe.
E6 INDOOR PROBE
SHORT: The control assumes that the ambient temperature is 90 degrees F and the
unit will operate. Change the probe.

E3 AMBIENT (INDOOR)
AIR PROBE OPEN or SHORT: Control will assume ambient temperature is 90 ° F when
in cool mode and 60 ° F when in heat mode. The unit will operate (see note
below)
E4 EVAPORATOR
TEMPERATURE PROBE OPEN or SHORT: Normal operation allowed. Change the probe.
E5 CONDENSER
TEMPERATURE PROBE OPEN OR SHORT: Normal operation allowed. Change the probe.
E7 motor operation
E9 heat pump failure
The error code must be in unit test mode to enter the function. Activation error code mode: press the time on / off button (see Figures 4 and 5). The LED error code for TIMER On / Off will flash 1bps (beats per second) when mode is activated. Press the temp button / hour button will display “00”. Constant presses will scroll through all the error codes stored. Press the Temp / Hour button to see the reverse order of the error code. The temperature set point will appear when the end of the stored error code is reached. (Each error code is listed once).

Exiting fault code mode: Pressing the
timer on / off button. Clearing error code: error codes become clear
By exiting the error code mode from memory.

Memory
Electronic controls have a memory to maintain all functions and settings, as installed by the user, in the event of a power failure. For example: Once power is restored to the unit, there is a delay of two seconds before the fan arrives and about three minutes before the compressor is activated, provided that the mode is set to cool. Went and the set point temperature is not found in the room.

Automatic component
protection
Your unit is equipped with automatic component protection. To protect the unit’s compressor, if you turn the unit off or if power is interrupted, there is a three-minute delay. The fan will not be affected. Also, if you switch from Cool mode to Fan only mode, and return to Cool mode, there is a delay of three minutes before the compressor returns.
