Symptom

Action
Fluctuating
water
temperature
(continued)
Hot water
temperature too high
Ensure hot water supply temperature is below
65ºC (minimum 55ºC for stored water and
50ºC 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 55ºC for stored water and
50ºC for combination boilers.
Logic Module
temperature setting
too low
Maximum temperature is set to a factory
default of 45ºC. To adjust refer to the important
information section (Safety Information) and
Controller Commissioning Instructions in the
Smart Shower Installation Guide.

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
SmartValve always blends a mix of both
hot and cold supplies therefore the output
temperature 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 40ºC. 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.

issue
Check that 2m patch lead is connected
between SmartValve and diverter. Refer to
Wiring Diagram Section in the Smart Shower
Installation Guide.

Turn off the power supply to the SmartValve,
leave isolated for at least 2 minutes. Reinstate
power supply and then following instructions
in the Settings Menu complete a Factory Reset,
then proceed to Configure Outlets.

Refer to pages 10 and 11.
Descale shower heads to clear spray jets.

Check the user guide for the hot water system
to verify symptoms and where required arrange
for servicing.
