Error code
05E
1. Measured Pool Temp <
Actual Pool Temp
a) The pool water temperature
sensor and PC Board are not
compatible.
Use the correct sensor.
b) The pool temperature sensor is
not in the correct position.
Position the sensor
correctly.
2. The Y shaped filter is blocked or
jammed resulting into lower water flow.
Clean the filter.
3. No water in pool or is lower than the
water inlet (Weir).
Fill the pool with water.
4. The plumbing is blocked or the valves
are damaged or closed.
Repair or replace the plumbing and/or valves.
5. Too much air in the plumbing result in
reduction in flow rate.
1. Remove air lock from the system.
2. Make sure that the circulation pump is working
correctly.
6. Circulation pump faulty.
a) Circulation
pump damaged.
Repair or replace
circulation pump.
b) Circulation
pump is too small
or the distance
from the heat
pump is too far.
Install correct circulation
pump for specific
application or shorten the
distance between
circulation pump and/or
the heat pump and/or
other equipment.
7. Excessive refrigerant charge volume.
Charge the correct volume of refrigerant specified on
the label.
8. Control cable of the high pressure
switch damaged or disconnected.
Replace the damaged cable or reconnect.
9. High pressure switch can not be reset.
Replace high pressure switch.
10. Input of the high pressure sensor is
shorted with common, error code 05E is
still displaying.
Replace the PC Board.
11. The refrigeration system is blocked
(by ice or dirt).
Find the cause of blockage and replace the filter
and/or re-vacuum the system.

1. Refrigerant leakage.
Detect leakage and repair. Vacuum, charge refrigerant
and start heat pump.
2. Control cable of the high pressure
switch damaged or disconnected.
Replace the damaged cable or reconnect.
3. Low pressure switch cannot be reset.
Replace low pressure switch.
4. Input of the high pressure sensor is
shorted with common, error code 05E is
still displaying.
Replace the PC Board.
5. The refrigeration system is blocked (by
ice or dirt).
