The ambient temperature of Digital Mixer Valve site (loft space, airing cupboard
etc...) can have an effect on showering temperature. Insulate all pipework as
required, particularly from the Digital Mixer Valve to the Shower Fitting.
The temperature indicated on the wireless controller display is measured
inside the digital mixing valve and due to site conditions is not necessarily the
temperature delivered at the shower outlet.
Fit 3 x AA batteries (supplied) into the wireless controller.
Depending on the type and version of your wireless controller, the
software revision number (eg. r04) may be briefly displayed, the
controller will then display its default time of 10:00.
Place Wireless Controller in approximate final
position (no more than 10 m (free air) from
Digital Mixer Valve) and test wireless signal by
pressing the " " and adjusting the temperature.
If temperature display remains unchanged and
"out of range" symbol is displayed, units are
unable to communicate with each other.
A sluggish response to button presses indicates
poor radio communication without the out of
range symbol being displayed.
If test fails, reposition unit(s) and
repeat test until satisfied shower will
work reliably.
Caution! Risk of product damage. Do not run
Pumped Valve (low pressure version) without a water supply for longer
than 5 minutes during test.
Isolate electrical supply to
Digital Mixer Valve.
Mark the fixing holes in
the required positions.
