• Page 3: Compatibility Thermotouch 4.3dC is compatible with almost all electric underfloor heating (UFH) systems available. Thermotouch can replace your existing underfloor heating thermostat and is compatible with many of the most popular thermostat brands’ floor sensor probes. Floor sensor probes include those rated at: 10kΩ @ 25°C (Default Thermotouch Sensor) 6.8kΩ @ 25°C 10kΩ @ 25°C 12kΩ @ 25°C 15kΩ @ 25°C 33kΩ @ 25°C Contact the manufacturer’s technical department and ask for the rating of the floor sensor at 25°C.
• Page 4: What’s in the box? Check you’ve got everything: • Thermotouch 4.3dC thermostat • Floor sensor probe (2m) • Floor sensor conduit (3m) • Fixing screws • Installation and user guide You will also need: • Electrical screwdriver • Standard electrical plate • Electric testing meter
• Page 5: Before you start Thermotouch 4.3dC should be installed at least 1.2m from the floor. It should be placed on an interior wall and in an area outside any wet zones (IP30). The device must be installed on an RCD protected circuit and away from drafts or heat influences. The floor sensor probe should be laid in a clear, temperature representative area of the floor. It is recommended to set the device to floor sensing mode wherever possible. The installation should be done by a qualified electrician in accordance with local electrical regulations. An inrush limiting device should be installed when using a DC transformer on the 5Amp relay.
• Page 6: Installing Thermotouch requires switching off mains power. Ensure safety and protect the thermostat by turning off the mains power before starting the installation. High voltage cables are involved.
• Page 7: Installing Thermotouch Choose a location An RCD protected electric underfloor heating system should be installed with an electrical plate in place. The underfloor heating cold tail should be pulled up through the electrical plate. The sensor probe must be installed within the wall cavity or pre chased channel in a solid wall. The thermostat can be mounted in a landscape or portrait position. The default screen orientation is landscape and must be changed in the settings if mounted in portrait.
• Page 8: Installing Thermotouch 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.
• Page 9: Installing Thermotouch Wiring diagram Connect Thermotouch to the underfloor heating (UFH) cold tail, heated towel rail, 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.
• Page 10: Installing Thermotouch 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. Fix in place with the screws provided. Now connect the ribbon cable and clip the face plate back into position.

Advanced settings Floor and ambient temp calibration, sensor calibration, switch rail and UFH controls on and off, change the language, factory reset, set your temperature limits.
• Page 14: Heating modes include several preset options that can be adjusted in the settings menu. Thermotouch will adjust your underfloor heating according to your preset heating schedule. You can manually override the schedule to select a different temperature. Thermotouch maintains the boost temperature until the next scheduled heating event. Manual mode allows you to select any temperature and make all changes yourself. Holiday mode maintains a low frost protection temperature while you are away. The heating system is off in holiday mode but will switch on automatically if the temperature gets too cold. The entire controller goes into holiday mode, meaning the towel rail will also be off.
• Page 15: Heating modes include Eco and Comfort. Eco mode maintains a low temperature, usually between 15-20°C, to save money on energy bills while keeping the chill off your floor. Comfort mode maintains a higher temperature, usually between 20-28°C, to keep you warm on a cold day. Both modes can be set to stay on indefinitely or for a 1, 2, or 4 hour boost, or until the next heating schedule event.
• Page 16: 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.
• Page 17: Heating schedule 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. You will need to ensure that all the times are consecutive and that the times do not run over midnight. Start setting up your underfloor heating schedule on page 18.
• Page 18: Heating schedule instructions include pressing menu, schedule, and UFH schedule. Select Monday to set the first heating event for the day. Set the desired time for heating to start in the morning. Adjust the temperature for the floor using the up and down arrows. The schedule includes multiple events with specific times and temperatures. Confirm the settings after adjustments.
• Page 19: Heating schedule Use the arrows on the left hand side of the screen to select the second heating event. Set your ‘OFF’ time and the Eco temperature, recommended between 15-20°C. Repeat steps for heating events 3 & 4, setting to low Eco temperature if not needed. Repeat steps for heating events 5 & 6, setting to low Eco temperature if not needed. All times need to be consecutive to ensure that the program runs correctly. Press confirm to save your settings.
• Page 20: Heating schedule Set the heating schedule for the rest of the week. Press back and then select Tuesday. Repeat steps to set the on/off times and temperatures for Tuesday. Press confirm to save your settings. Select the next day and repeat the steps to set a heating schedule for all days of the week. Press confirm to save your settings and press back to go back to the menu and home screen.
• Page 21: Heating schedule The copy function is to copy the times from the underfloor heating schedule across to the heated towel rail schedule. Each day does need to be programmed individually. When only using some of the on/off periods, all the times need to be consecutive and the times cannot be over midnight. When the thermostat is in portrait mode, the heating times go down the two columns not from left to right.
• Page 22: Appliance controls allow you to manage another appliance from the home screen. The appliance will remain on until it is turned off again. The appliance can be scheduled to switch on and off according to its heating schedule. The appliance boost feature activates the appliance for 1, 2, or 4 hours before returning to the heating schedule.
• Page 23: Appliance relay is separate from the underfloor heating relay, allowing for two distinct schedules. You can have one on without the other. To synchronize the towel rail with underfloor heating, copy the underfloor heating schedule to the appliance. After setting the underfloor heating schedule, press Copy, then OK, and confirm to save settings. This action copies all on/off times from the underfloor heating schedule to the appliance schedule. You still need to set 'ON' or 'OFF' for each time.
• Page 24: Appliance schedule setup instructions are provided. To set up a separate schedule for the appliance relay, follow specific steps. Press menu, then schedule, and select HTR schedule. Adjust the times of your schedule using the arrows and select 'ON' and 'OFF' for each time. All times need to be consecutive, even if set to 'OFF'. Repeat the process for each day of the week. Press to save the schedule.
• Page 25: Advanced settings can be accessed by pressing Menu and then the green Settings icon. This menu allows you to set up and control all of the more advanced settings for your Thermotouch Thermostat. High temperature protection range is 20°C - 40°C. Low temperature protection range is 5°C - 15°C. Maximum set temperature is 5°C - 40°C. Floor temperature calibration range is -10°C - 10°C. Ambient temperature calibration range is -10°C - 10°C. Language options include English, French, and German. Adaptive start and window detect features can be turned ON or OFF. Detect time can be set between 2 to 30 minutes.
• Page 26: Energy saving features include Adaptive Start and Open Window Detector. With Adaptive Start, Thermotouch measures how long it takes for your floor to heat up, ensuring the target temperature is achieved at the set time. If you set your heating schedule to 24°C at 07:00, the floor will be at 24°C at that time without needing to start early. Thermotouch learns from the first time you enable the heating schedule, initially turning on an hour early and optimizing heat up time over 7 days. The Open Window Detection feature detects sudden drops in temperature and switches off heating to eliminate wasted energy. Thermotouch will resume heating after 30 minutes if the temperature has stabilized. You can activate and adjust these features in the advanced settings menu.
• Page 27: Factory reset To do a factory reset on the unit, navigate to the menu screen and select the green advanced settings box. Use the arrows to move to page 3 of the settings. Use the smaller arrows next to Restore to change from 'NO' to 'Yes'. Press the tick button in the bottom right hand corner of the screen. The unit will take a couple of seconds to switch off and reset to factory settings. Do not touch the screen while it is performing the reset. This will totally erase the heating program and any adjusted settings. Please note that the current date and time that has been set will not be erased.
• Page 28: Locking the entire keypad requires navigating to the main home screen and pressing and holding the time in the top left corner for approximately 4 seconds until a padlock symbol appears. To unlock the keypad, press and hold the time again until the padlock symbol disappears. You can also lock just the advanced settings to prevent accidental changes while still allowing program adjustments. To lock the advanced settings, navigate to the menu screen and press and hold the green box for approximately 3 seconds until a padlock symbol appears in the top corner of the green box. Unlocking the advanced settings requires being on the menu screen and pressing and holding the Thermotouch logo in the top right corner until the padlock on the green settings box disappears.
• Page 29: Troubleshooting Guide Very high temperature reading Possible causes include software issues, incompatible sensors, multiple sensors installed, high temperature influences, faulty floor sensors, and incorrect settings. Factory reset may resolve software issues. Use a multimeter to test the resistance of the sensor probe. Ensure only one sensor probe is connected to the thermostat. Check for high temperature influences around the thermostat or floor sensor probe. Floor sensors should not be covered by insulating objects. Damaged or faulty floor sensors may need replacement or adjustment to ambient sensor mode. Changing advanced settings can affect temperature readings. Refer to the defaults listed in the manual for advanced settings. Covering a floor heating system can cause overheating issues.
• Page 30: Problem Possible causes Things to try Isolate power and check that a compatible NTC10K sensor probe is connected to terminals 6 & 7. If no sensor is installed you will need to have one installed or run the system on air/ambient temperature only. If there is a sensor connected then it may be faulty. The sensor is rated at 10KΩ at 25C and fluctuates with temperature differences. Depending on the temperature the resistance reading should be somewhere between 8 - 12KΩ. If the sensor is faulty it will need to be replaced. Check that there is only 1 sensor probe connected to your thermostat. If a DC output transformer has been used it can cause the relay to stick.
• Page 31: Technical data includes supply voltage, maximum load, and relay specifications. Supply voltage is 230/240V 50/60Hz.
