Service Analyser Codes - Waterco Ultra Guide D'utilisation Et D'entretien

Service Analyser Codes (All Models)
Most problems will be detected by the electronic control and a code will appear on the
temperature display. Make sure you follow the Action / Remedy instructions where
possible, before making a service call request and avoid paying unnecessary service call
fees. If the code remains on the display after you have followed the Action / Remedy
instructions, please contact Waterco.
Code
Problem - Action / Remedy
Problem: The intake temperature probe has a loose connection or is faulty.
oC2, Sc2
The probe will need to be checked and replaced, if required.
Action / Remedy: Contact customer service.
Problem: No water flow, not sufficient water flow through the pool heat pump
nFL
or the water pressure switch needs to be adjusted (not covered by the
warranty) or is defective.
Action / Remedy: If the pool pump is connected to the pool heat pump,
make sure the electronic control that runs the pool pump and pool heat pump
are programmed correctly.
If the code is still displayed:
Make sure the pool pump is switched ON;
-
Press ON/OFF to restart the pool heat pump;
-
On new installations, ensure the installation instructions were respected;
-
Check that the pool water level is correct, that the pool pump is filled with
-
water to the rim and that water is flowing correctly through the pool pump
to the pool heat pump;
Check swimming pool and pool pump skimmer baskets and the drain at
-
the bottom of the pool for obstructions;
Check the filter cartridges for obstructions (wash or change the
-
cartridges);
Carry out a backwash for sand filters and ensure they are working
-
correctly;
Ensure that the bypass valves are in the correct positions so that the
-
water flows adequately;
Ensure vacuum robot or other cleaners are disconnected so that the water
-
flows freely;
Check that there are no leaks on the pool plumbing (there should be no air
-
leaks in the pipe work);
If you have a two speeds pool pump, make sure it is set at the highest
-
speed.

Service Analyser Codes

Code
DEF
Problem - Action / Remedy
Problem: Normal defrost cycle. The fan blades are turning, but the
compressor has stopped. For Ultra and Reversible (XLR) model, the fan
blades do not turn but the compressor runs.
Action / Remedy: Normal during defrost cycle.
Atmospheric conditions as well as the pool water temperature should not be
below the minimum operating temperatures, as stated below, in order to
obtain efficiency and avoid codes from appearing on the electronic control
temperature display. These codes are not generally a problem with the pool
heat pump at these conditions and are not covered under warranty.
If temperatures are below the minimum temperatures the pool heat pump
should not be operated and must be switched off.
For Ultra and Reversible (XLR) units, they will automatically stop without
human intervention.
Atmospherics conditions
Model
must be above
32 °F (0 °C)
Ultra
43 °F (6 °C)
Reversible (XLR)
52 °F (11 °C)
All others
For Ultra or Reversible (XLR) Model: If the unit performs 4 consecutive
cycles (heating and defrost) within 1 hour, the unit goes into protection mode
and alternately displays the water temperature and the DEF code. The fan
motor runs for 30 minutes to cool the evaporator and then stops.
compressor is always off. The unit restarts automatically when the outside
temperature is 43 °F (6 °C) and more.
If the code stays on permanently:
Ensure the evaporator is clean. If not, switch the unit OFF from the
-
circuit breaker (fuse) and use a garden hose to lightly clean the
evaporator. Allow it to dry before re-starting the pool heat pump to avoid
premature ice build up on the evaporator.
Ensure installation instructions have been followed. Improper installation,
-
e.g. no air circulation, could lead to the pool heat pump continually going
into defrost mode and the installation will need to be corrected by the
owner. This situation is not covered by the warranty.
