Installing Thermotouch

1. 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
2. Choose a location
   • At this stage, it is likely that a RCD protected electric Underfloor
   • The 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.
   • The Thermostat can be mounted in a landscape or portrait position.
   • Please note the default screen orientation is landscape so if mounting in portrait this will need to be changed in the settings once the unit has been powered up.
3. Maximum distances
   • Thermotouch can be installed up to 50m away from the Underfloor
   • The heating system is controlled, 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.
4. Wiring diagram
   • Connect Thermotouch to the Underfloor Heating (UFH) cold tail,
   • Heated Towel Rail (or another additional appliance), power supply and floor temperature sensor.
   • The floor temperature sensor is not polarity-sensitive.
   • If using a DC transformer when installing a low-voltage appliance to the 5A relay an inrush limiting device must be installed.
5. Fix to the wall
   • Insert a small flat screwdriver in the groove on the underside to lever the face plate away from the back plate.
   • Carefully disconnect the ribbon cable and align the Thermotouch with the mounting positions on the pre-installed electrical plate.

  • 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.
  • Please note this puts the entire controller into holiday mode which means that the towel rail will be off as well.
• Eco
  • Maintains a low temperature, usually between 15-20°C, to save money on energy bills while keeping the chill off your floor.
• Comfort
  • Maintains a higher temperature, usually between 20-28°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 an hour boost, or until the next heating schedule event.

Set the Time and Date

• When you first switch Thermotouch on, you will need to set the current time and date.
• You can do this by pressing Menu and then Date & Time ( ).
• Use the arrows to select the right date and time and then press confirm to save.
• Setting up a schedule ensures energy efficiency and convenience by automatically changing the temperature of your Underfloor Heating system.
• There are 6 heating events for every day. Most people treat them as 3 on/off cycles.
• All 7 days are programmed independently.
• If you don’t want to use all the heating events you can skip events by setting it to the same temperature as the previous event.

Energy Saving Features

Adaptive Start

• With the Adaptive Start feature enabled, Thermotouch 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!
• Thermotouch 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, Thermotouch can detect sudden drops in temperature and will switch off your heating to eliminate wasted energy.
• Thermotouch will come back on after 30 minutes, provided the temperature has stabilised.
• You can activate and adjust these features in the advanced settings menu.

Factory Reset

Troubleshooting

Electric floor heating systems should not be covered by insulated objects such as rugs, dog beds or furniture that prevent air flow over the floor. Covering a floor heating system in this way can cause overheating issues which can damage floor coverings and cause heating cable failure.
