❹ Troubleshooting; I Device Behaviour - Zodiac Heat Select ZS500 Series Instructions For Installation And Use Manual

❹ Troubleshooting
• Before you contact your reseller, please carry out these few simple checks using the following
tables if a problem occurs.
• If the problem continues contact your reseller.
• : Actions reserved for a qualified technician

4.1 I Device behaviour

• On start-up, the device remains "paused" for 30 seconds before it starts operating.
• When the setpoint temperature is reached, the heat pump stops heating: the water temperature
is higher than or equal to the setpoint temperature.
The device does • When the water flow rate is zero or is not enough, the heat pump stops: check that the water
not start heating is circulating correctly in the heat pump (see § "2.5 I Presentation of the menu") and that the
straight away hydraulic connections are correct.
• The heat pump stops when the outdoor temperature falls below -12 °C.
• It may be that the heat pump has detected an operating fault (see § "4.2 I Error code display").
• If you have checked these points and the problem persists: contact your reseller.
• Often called condensation. This water is the moisture contained in the air which condenses
on contact with certain cold mechanisms in the heat pump, especially on the evaporator. The
more damp the air, the more condensation your heat pump will produce (your device may
drain several litres of water per day). This water is retrieved by the base of the heat pump and
The device is
drained through the holes.
draining water
• To check that the water is not coming from a leak in the pool circuit on the heat pump, shut
down the heat pump and run the filtration pump for the water to circulate in the heat pump. If
the water continues to flow through the condensation drains, there is a water leak in the heat
pump; contact your reseller.
• Your heat pump will soon switch to its defrost cycle to melt the ice.
The evaporator is
• If your heat pump cannot manage to deice its evaporator, it will stop itself; this means that the
iced over
outdoor temperature is too low (below -12 °C).
• This may occur when it is in a defrost cycle and the water is converted to gas.
The device is
• If your heat pump is not in its defrost cycle, this is not normal. Switch off and disconnect the
"smoking"
heat pump immediately and contact your reseller.
• If there is no display, check the supply voltage and the F1 fuse.
• When the setpoint temperature is reached, the heat pump stops heating: the water temperature
is higher than or equal to the setpoint temperature.
• When the water flow rate is zero or is not enough, the heat pump stops: check that the water

working
• The heat pump stops when the outdoor temperature falls below -12 °C.
• It may be that the heat pump has detected an operating fault (see § "4.2 I Error code display").
• The device is in an empty time range. Deactivate the "time range" mode to launch manual
operation or modify the time range programming.
• The operating mode is not powerful enough (device in "Eco Silence" or "Smart" mode). Switch
to "Boost" mode and set the filtration to 24/24 manual while the temperature rises.
• It may be that the heat pump has detected an operating fault (see § "4.2 I Error code display").
• Check that the automatic filling valve is not stuck in open position; this will keep supplying cold
