Thermogroup Thermotouch 7.6iG Programmable thermostat for Electric

Underfloor Heating

Compatibility

Sensor probes
This thermostat is compatible with Thermogroup NTC 10kΩ @ 25°C floor sensor probes.

Heating systems
This thermostat is compatible with all Thermogroup electric Underfloor Heating systems.

Replacing an existing thermostat?
Contact the manufacturer’s technical department and ask for the rating of the floor sensor at 25°C. If you have an existing floor probe from another thermostat that is not compatible, set your thermostat to ambient temperature sensing mode.

What’s in the box?

Check you’ve got everything:

• Programmable thermostat
• Floor sensor probe (3m)
• Floor sensor conduit (2m)
• Fixing screws
• Installation and user guide
• Mounting plate (Portrait included with thermostat,
• landscape to be purchased additionally)

You will also need:

• Electrical screwdriver
• Standard electrical mounting plate
• Electrical test meter

Before you start

Thermotouch 7.6iG should be:

• Installed at least 1.2m from the floor
• On an internal wall
• Outside any wet zones (IP30)
• Installed on a RCD protected circuit
• Away from any hot or cold influences
• Installed so that the floor sensor probe can be laid in a clear, temperature-representative area of the floor
• Installed by a qualified electrician, in line with current electrical regulations and relevant local standards

Installing Thermotouch

Switch off mains power
You will be installing Thermotouch 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.

CAUTION High Voltage Cables

Pre-wiring complete
At this stage it its likely that an RCD-protected electric Underfloor Heating system has been installed and an electrical plate is already in place. The Underfloor Heating cold tail should be pulled up through the electrical plate, and the sensor probe installed (in the conduit provided) within the wall cavity or pre-chased channel in a solid wall.

Maximum distances
Thermotouch 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. Multiple heating cables can be connected to the thermostat in parallel. When connecting multiple heating cables ensure that the load does not exceed the load of the thermostat (16Amps).

Un-clipping the mounting plate

1. Remove the Thermostat from the box and press upwards on the main square unit.
2. This will release the main unit from the mounting plate and then you will need to unclip the ribbon cable from the back of the screen.
3. The mounting plate consists of two parts. The black plate containing the terminal block is to be screwed to your standard electrical mounting plate installed.
4. Once wired up, the ribbon cable needs to be plugged back into the back of the screen and the main unit needs to be clipped back onto the mounting plate. Locate the thermostat onto the black steel clips of the mounting plate.
5. Slide the thermostat unit on the steel clips and push down to secure the thermostat in place.

Fix mounting plate
Wire up the Underfloor Heating cold tail, mains power and sensor cables to the terminal block as per the wiring diagram on page 11. The black metal then needs to then be screwed to the electrical mounting plate.

Wiring diagram
Connect the Thermostat to the Underfloor Heating (UFH) cold tail, power supply and floor temperature sensor. The floor temperature sensor is not polarity sensitive.

Fix thermostat in place
Clip the plastic mounting plate over the steel plate and locate the thermostat onto the steel clips. Ensure the arrows on the metal plate and mounting plate are pointed upwards. Slide the thermostat unit onto the steel clips and push down to secure the thermostat in place.

Warning – Do not force the thermostat into place as this will break the clips and result in being unable to install the unit.

Switching on for the first time

Do not switch your Underfloor Heating on unless the entire heating cable, cold tail joint and end termination are fully encased in tile adhesive. It is important that all adhesives and grouting 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 2-3°C per day. Observe any maximum temperature guidelines from your floor manufacturer.

Heating Modes

When your thermostat is on you can tap to switch between Manual and Schedule heating modes.

Manual mode
Your thermostat will simply maintain the temperature you set manually until you ask it to do something else!

Schedule mode
Your thermostat will follow a heating schedule that you can set up by following the instructions on.

Temperature override
When the thermostat is in Schedule mode, it is possible to manually override the temperature without adjusting the schedule or switching to manual mode.
You can adjust the temperature with the arrows.

If you override the temperature while the thermostat is running the heating schedule, the new override temperature will be maintained until the next scheduled temperature change. The thermostat will then revert to the preset heating schedule. In the advanced settings (see page 22) you can choose between 5 different schedule options. The default setting is all days programmed individually (1-7 Flashing). If you would prefer one of the other scheduling options listed below please ensure this is changed in the advanced setting prior to setting up your schedule.

• 1234567 Flashing – Every day is different. Every day can be set with separate heating events.
• 1234567 – Mon-Sun the same. Every day will follow the same heating schedule.
• 123456 – Mon-Sat the same and Sunday on a separate schedule.
• 12345 – Weekdays (Mon-Fri) on one schedule and weekends (Sat & Sun) on a separate schedule.
• No Numbers – Program off. To be used as manual only.

What is a heating event?
A heating event is any opportunity to change the temperature in your heating schedule.

Energy Saving Features

You can activate and adjust these features in the advanced settings menu.

Adaptive Start
With the Adaptive Start feature enabled, your thermostat will measure how long it takes for your individual floor 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 floor will be at 24°C at 07:00. No need to set the heating to come on early! Your thermostat starts learning from the first 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.
