Low / no flow
Seasonal conditions
See previous point.
Incorrect Aqualisa
SmartValve
TM
fitted
If water supplies are gravity fed, the PUMPED
Aqualisa SmartValve
TM
must be used (unless a
separate stand alone pump is being utilised).
Refer to the Smart Installation Guide.
Water supply issue
For the Standard Aqualisa SmartValve
TM
- Ensure
water is turned fully on at the mains and at the
servicing valve in the supply.
Ensure isolation valves are fully open.
Mixed water supplies
For standard Aqualisa SmartValve
TM
- ensure
hot and cold supplies are from the mains water
supply.
Restriction in the
waterway
See same cause in 'Pump noisy and low / no
flow' symptom.
Blocked or kinked
hose liner
Where a flexible hose is fitted, unscrew the
shower hose from the outlet connection and
turn the shower on.
Incoming mains water
pressure or flow too
low (Standard Aqualisa
SmartValve
TM
only)
After confirming that the filters are clear, check
with the local water authority.
Separate, stand alone
pump not activating
(Standard Aqualisa
SmartValve
TM
only)
Ensure sufficient flow to activate the
flow switches of the pump. Refer to
IMPORTANT INFORMATION section in
the Smart Installation Guide.
Aqualisa
SmartValve
TM
pump
not activating
Refer to Setting Water System Mode section in
the Smart Installation Guide, ensure mode is set
to Normal or ECO Gravity setting.
Shower head or
Aqualisa SmartValve
TM
is set to ECO mode
Refer to page 10 of this guide and to the above
point.
Unable to adjust or
control temperature
Reversed inlet water
supplies (i.e. Hot
supply feeding cold
inlet and vice-versa)
Ensure correct water supply to specified inlet
connection of the Aqualisa SmartValve
TM
.
Fluctuating water
temperature
Incorrect setting
on Logic Module
of Aqualisa
SmartValve
TM
If hot water supply is from a combination
boiler- the Logic module mode MUST be set to
COMBI. Refer to Setting Water System Mode
section in the Smart Installation Guide.
Airlock in water
supplies (for gravity
fed systems only)
See “Air lock” in Possible Cause section on
page 19.
Fluctuating water
temperature
(continued)
Hot water
temperature too high
Ensure hot water supply temperature is below
65
º
C (minimum 55
º
C for stored water and
50
º
C for combination boilers).
Communications
issue
Check data cable connections and that there is
no visible damage.
Combination boiler
unable to meet
demand
Check if another outlet in the property is being
used at the same time.
Check that the hot water temperature is stable
at another high flowing outlet (e.g. bath hot tap
- run at maximum flow rate), additionally run a
cold outlet at 1/3 of a maximum flow rate. If the
same issue is evident on these outlets, contact
your boiler manufacturer.
Temperature
too low
Low hot water
temperature
Check that domestic hot water temperature
is a minimum of 55
º
C for stored water and
50
º
C for combination boilers.
Logic Module
temperature setting
too low
Maximum temperature is set to a factory
default of 45
º
C. To adjust refer to the important
information section (Safety Information) and
Controller Commission Instructions in the Smart
Installation Guide.
Temperature too
low - Controller
temperature ready
display does not
stabilise
Hot water supply
issue
Check another hot water outlet to ensure that
hot water is available.
Mixed water supplies
Water supplies MUST be from the same source:
MUST NOT be gravity hot and mains cold.
Unbalanced water
supplies
For mains fed systems the cold and hot feeds
should be as evenly balanced as possible -
especially for HP unvented systems.
Combination boiler
unable to meet demand
See same cause in 'Fluctuating Water
Temperature' symptom.
Temperature
too hot
Seasonal conditions
In the warmer months, the mains water
temperature can rise to ambient level. The
Aqualisa SmartValve
TM
always blends a mix of
both hot and cold supplies therefore the output
temperate at fully cold (controller setting) will
always be higher than the incoming cold water
supply.
Temperature
too hot
Seasonal conditions
(gravity fed systems
only)
For installations which utilise a cold water
storage supply (gravity fed system), the ambient
temperature in the loft can rise to above 40
º
C.
In turn, this warms the stored water. Check
by running a cold tap that is supplied from the
water storage. N.B. Kitchen taps are normally
fed from the mains water system.
Maximum
temperature setting
is not to your
preference
Settings need
adjusting
Refer to section 'Temperature too low', possible
cause 'Logic module setting too low'
