Introduction
Thank you for buying our Thermotouch 5235W
thermostat. We hope you will enjoy the ease of
use offered by the touchscreen and intuitively
designed interface. You can program the
thermostat any way you want with the options
provided under Heating Schedule and User
Settings.
The thermostat will switch on your heating
system at predetermined times each day of
the week. You can set individual temperatures
for up to six seperate periods, called events,
for each day of the week. Lowering the
temperature when your home is unoccupied
will reduce your energy costs without reducing
comfort.
The thermostat comes with a preset heating
schedule suitable for most homes. Unless you
change the settings, the thermostat will
operate according to this preset heating
schedule.
The thermostat features an adaptive function that
automatically changes heating start times to ensure
that the required temperature has been reached
at the beginning of any specific event. After a few
days, the adaptive function will have learned how
much earlier the heating must be switched on.
The resistive touchscreen only requires a soft tap
with your fingertip to register the touch.
In this manual, the touch areas on the screen will be
referred to as buttons.
The Wi-Fi version of the this Thermotouch offers
remote control of your underfloor heating through
the SWATT® (Smart Wi-Fi and Touch Thermostat)
app, which can be downloaded from both Google
Play and App store.

Installing your thermostat
1. Switch off main power

voltage mains electrical circuit. To ensure your safety and
to protect the thermostat, switch off the mains power
before you start the installation.
CAUTION
Must be installed
on an RCD circuit

Installing your thermostat
2. Installation Location
At this stage it is likely that an RCD protected electric underfloor heating system has been installed
and a standard electrical plate is already in place.
The underfloor heating cold tail should be pulled up through the back plate, and the sensor probe
installed (in the conduit provided) within the wall cavity or pre chased channel in a solid wall.

Installing your thermostat
3. Maximum Distance
Your thermostat can be installed up to 50m away from the underfloor heating system it is controlling,
provided that the floor sensor is used to control the temperature.
Underfloor heating cold tails and floor sensor probes can be extended up to 50m.
50m max.
Connect multiple heaters in parallel.

Installing your thermostat
5. Fix Mounting Plate
Fix your thermostat in position onto the electrical plate in either the vertical or horizontal position.
Ensure the unit is switched off using the switch on the side of the unit, to allow for the screen to be

Installing your thermostat
7. Switching on your system
It is important that all adhesives and grouts are dry and fully cured before you
switch on your underfloor heating.
Most adhesives take between 7 to 10 days to cure. Follow manufacturer
guidelines.
The temperature of your underfloor heating should be increased gradually to
avoid thermal shock in the floor. Start at 15°C and work up to your desired
temperature increasing 2-3°C per day.
Observe any maximum temperature guidelines from your floor manufacturer.
Australian regulation states the heating cannot exceed 28°C.
Wait for
7 - 10 Days
before you
switch on
