Compatibility
ThermoSphere dual controls are compatible with
almost all electric underoor heating (UFH) systems
available.
ThermoSphere dual control can replace your existing
underoor heating thermostat as it's compatible
with many of the most popular thermostat brands’
oor sensor probes including those rated at:
• 6.8kΩ @ 25°C
• 10kΩ @ 25°C
• 12kΩ @ 25°C
• 15kΩ @ 25°C
• 33kΩ @ 25°C
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:
• ThermoSphere Dual Control
• Floor sensor probe (2m)
• Floor sensor conduit (3m)
• Fixing screws
• Manual and warranty information
You will also need:
• Electrical screwdrivers
• Deep electrical back box

4
Before you start
Your thermostat should be:
• Installed 1.2 - 1.5m from the oor
• On an interior wall
• In an area 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
clear, temperature representative area of the oor.
• Set to oor sensing mode wherever possible
• In an open area of the room
• Installed by a professional, in line with current IEE
regulations and 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 before you start the
installation.

Installing your thermostat
2. Choose a 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.

Installing your thermostat
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.
50m max.

Heating schedule
Setting up a schedule ensures energy efciency and
convenience by automatically changing the temperature
of your underoor heating system.
Each day of the week can be programmed
independently.
There are 6 heating events for every day. Most people
treat them as 3 on/off cycles.
Start setting up your underoor heating schedule on
page 16.

A typical heating schedule
Everyone is different, but typical heating schedule for
a working family would have the heating on in the
morning and evening during the week. At weekends
heating can be on in the morning, for a period in the
afternoon and then again in the evening.
You can adjust the time and temperature of any of
these heating events to suit your lifestyle.

Appliance schedule
Copy your heating schedule to an appliance (such as
an electric heated towel rail or mirror de-mister) that is
connected to your thermostat.
When you have nished setting your UFH schedule press
Copy, press OK and then press conrm to save your
settings
This will copy all of the on/off times from your UFH
schedule to the appliance schedule.
Now select a day, use the arrows to select the heating
events and set the appliance to on or off. You can also
adjust the times if you want to.
There is no temperature setting for the appliance because
it is not connected to a temperature sensor.
.
20
Appliance controls
You can control another appliance, such as an
electric heated towel rail from the home screen.
On
The appliance will stay on until you turn it off again.
Schedule
The appliance will switch on and off according to the
appliance heating schedule
Appliance boost
Switches the appliance on for one hour, 2 hours
or 4 hours and then back to the appliance heating
schedule.
21
Heating modes
Your thermostat has several preset heating modes
that can be adjusted in the settings menu.
Eco
Maintains a low temperature, usually between 16
-18°C, to save money on energy bills while keeping
the chill off your oor.
Comfort
Maintains a higher temperature, usually between
22 - 27°C, that will keep you warm on a cold day!
Both of these modes can be set to stay on forever
until you change it, for a 1, 2 or 4 hour boost, or until
the next heating schedule event.
22
Heating modes
Schedule
Your thermostat will follow the temperatures and
times set up in your heating schedule.
You can manually override the schedule using the up
and down arrows to select a different temperature.
Your thermostat will maintain the boost temperature
until the next scheduled heating event.
Manual
You can manually select any temperature and must
make all temperature changes yourself.
Holiday
Maintains a low frost protection temperature, usually
between 5 - 10°C, while you are away. Your heating
system is off, but will switch on automatically if the
temperature gets too cold.
23
Energy saving features
Adaptive Start
With the Adaptive Start feature enabled, your thermostat will measure
how long it takes for your individual oor to heat up and ensure the target
temperature is achieved at the set time.
So if you set your heating schedule to 24°C at 07:00, the oor will be at
24°C at 07:00. No need to set the heating to come on early!
Your thermostat starts learning from the rst time you enable the heating
schedule. It turns on an hour early to start with and gradually optimises the
heat up time over 7 days.
Open Window Detector
When the Open Window Detection feature is enabled, Your thermostat
can detect sudden drops in temperature and will switch off your heating to
eliminate wasted energy.
Your thermostat will come back on after 30 minutes, provided the
temperature has stabilised.
24
You can activate and adjust these features in the
advanced settings menu. See page 26
