thermostat that is not compatible, set your
thermostat to ambient temperature sensing mode.
(Not advisable for timber or other temperature sensitive oors).
Replacing an existing thermostat?
Contact the manufacturer's technical department
and ask for the rating of the oor sensor at 25°C.

What’s in the box?
Check you've got everything:
• Thermostat
• Floor sensor probe (3m)
• Floor sensor conduit (2m)
• Fixing screws
• Installation guide and warranty information
You will also need:
• Electrical screwdriver
• Deep electrical back box

Before you start
Your thermostat should be:
• Installed 1.2 - 1.5m from the oor
• On an internal wall
• Outside any wet zones (IP30)
• Installed on an RCD protected circuit
• Away from drafts or heat inuences
• Installed so that the oor sensor probe can be laid in a
heated area of the oor
• Installed by a professional, in line with current
electrical regulations and relevant local standards

Installing your thermostat
1. Switch off mains power
You will be installing your thermostat as
part of a high voltage mains electrical
circuit. To ensure your safety and to
protect the thermostat, switch off the
mains power and remove fuse from the
spur before you start the installation.

2. Installation location
At this stage it its likely that an RCD protected
electric underoor heating system has been
installed and a back box is already in place.
The underoor 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
underoor heating system it is controlling, provided that the
oor sensor is used to control the temperature.
Underoor heating cold tails and oor sensor probes can be
extended up to 50m.
Connect multiple heaters in parallel.
50m max.

4. Release mounting plate
Use a at screwdriver to press is the catch and push the fascia

10. Switching on your system
It is important that all adhesives and
grouting is dry and fully cured before you
switch on your underoor heating.
Most adhesives take between 7 to 10 days
to cure. Follow manufacturer guidelines.
The temperature of your underoor heating
should be increased gradually to avoid
thermal shock in the oor. Start at 15°C
and work up to your desired temperature
2-3°C per day.
