Summary of Contents
- Page 1: Thermotouch 5235W Wi-Fi enabled thermostat Simplified instruction version
- Page 2: Introduction Thank you for buying our Thermotouch 5235W thermostat. You can program the thermostat any way you want with the options provided under Heating Schedule and User Settings. The thermostat features an adaptive function that automatically changes heating start times. The thermostat will switch on your heating system at predetermined times each day of the week. You can set individual temperatures for up to six separate periods, called events, for each day of the week. Lowering the temperature when your home is unoccupied will reduce your energy costs without reducing comfort. The resistive touchscreen only requires a soft tap with your fingertip to register the touch. In this manual, the touch areas on the screen will be referred to as buttons. The Wi-Fi version of this Thermotouch offers remote control of your underfloor heating through the SWATT® app. The thermostat comes with a preset heating schedule suitable for most homes.

- Page 5: Before you start Check you have got everything: - 5235W thermostat - Mounting plate - Fixing screws - Electrical screwdriver - Wire strippers - Fixing bracket - 3M sensor probe - 2M sensor conduit - Electrical test meter Your thermostat should be: - Installed 1.2 - 1.5m up from the floor - On an internal wall - Outside any wet zones (IP21) - Installed on an RCD protected circuit - Away from drafts or heat influencers - Installed so that the floor sensor probe can be laid in a heated area of the floor - Installed by an electrician, in line with current electrical regulations and relevant local standards
- Page 6: Installing your thermostat Switch off main 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. Must be installed on an RCD circuit
- Page 7: Installing your thermostat Installation location An RCD protected electric underfloor heating system has likely been installed. A standard electrical plate is already in place. The underfloor heating cold tail should be pulled up through the back plate. The sensor probe should be installed within the wall cavity or pre chased channel in a solid wall.
- Page 8: Installing your thermostat Your thermostat 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. Connect multiple heaters in parallel.
- Page 9: Installing your thermostat Wiring diagram Connect the thermostat to the underfloor heating cold tail, power supply, and floor temperature sensor. The floor temperature sensor is not polarity sensitive.
- Page 10: Installing your thermostat Fix mounting plate Fix your thermostat in position onto the electrical plate in either the vertical or horizontal position. Ensure the unit is switched off using the switch on the side of the unit, to allow for the screen to be clipped into position.
- Page 11: Installing your thermostat It is important that all adhesives and grouts 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 increasing 2-3°C per day. Observe any maximum temperature guidelines from your floor manufacturer. Australian regulation states the heating cannot exceed 28°C.
