Compatibility
Thermotouch Manual Glass is compatible with
Thermogroup NTC 10K floor sensor probes.
NTC 10kΩ@ 25°C
If your existing floor probe is from another thermostat
manufacturer and is not compatible, set your
thermostat to ambient temperature sensing mode.
(Not advisable for timber or other temperature sensitive floors).
Replacing an existing thermostat?
Contact the manufacturer’s technical department
and ask for the rating of the floor sensor at 25°C.

What’s in the box?
Check you’ve got everything:
• Manual thermostat (5215 or 5216)
• Floor sensor probe (3m)
• Floor sensor conduit (2m)
• Fixing screws
• Installation guide
You will also need:
• Electrical screwdriver
• Deep electrical back box
• Electrical test meter

Before you start
Your thermostat should be:
• Installed 1.2 - 1.5m from the floor
• On an interior wall
• Outside any wet zones (IP30)
• Installed on an RCD protected circuit
• Away from drafts or heat influences
• Installed so that the floor sensor probe
can be laid in a heated area of the floor
• Installed by a professional, in line
with current IEE 17th Edition Part P
regulations and local standards

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

3. Maximum distances
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.
Connect multiple heaters to the thermostat in parallel.
50m max.

8. Switching on your system
It is important that all adhesives and
grouting is 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 2-3°C
per day.
Observe any maximum temperature
guidelines from your floor manufacturer.
Wait for
7 - 10 Days
before you
switch on
