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.

If the probe does not read between 8 to 12K then it is likely to be a sensor probe from a different manufacturer and will need to be replaced with a Thermogroup 10K sensor probe or the settings changed. More than one sensor installed Sometimes more than one floor sensor is connected to the thermostat by mistake. This results in a high resistance and incorrect temperature readings that are much higher than normal. Check that there is only 1 sensor probe connected to your thermostat. High temperature influence Check whether there are any high temperature influences around the thermostat or the floor sensor probe. If the floor sensor is in the floor and situated near a hot water pipe it will read a high temperature. If the floor sensor is in an area of the floor covered by a mat or dog bed this area of the floor would read much hotter than areas of the floor not covered by insulating objects* Faulty floor sensor The floor sensor probe could be damaged or faulty. If this was correctly installed in a conduit this can be replaced. Alternatively, set the thermostat to ambient sensor mode. See page 13. Incorrect setting Changing some of the advanced settings can affect the temperature reading. To correct this either do a factory rest on the unit or check the advanced settings on the unit compared to the defaults listed on page 25. *Electric floor heating systems should not be covered by insulated objects such as rugs, dog beds or furniture that prevents 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. www.thermogroup.com.au | 1300 368 631 29 Need a hand? Call us on 1300 368 631 Problem 0°C Temperature reading Possible Causes No floor sensor installed 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. Disconnect the sensor from the terminals and test the resistance using a multimeter on the 20K setting. Faulty floor sensor The sensor is rated at 10K at 25C and fluctuates with temperature differences. Depending on the temperature the resistance reading should be somewhere between 8 - 12K If the sensor is faulty it will need to be replaced. Flashing back-light or any fault with the display or button functions More than one sensor installed Sometimes more than one floor sensor is connected to the thermostat by mistake. This results in a high resistance and incorrect temperature readings that are much higher than normal. Check that there is only 1 sensor probe connected to your thermostat. Bad connection between display and power unit Take the front plate off of the thermostat using a flat screwdriver. Unplug the white ribbon cable and check the cable and pins for any signs of damage. If no damage is found replace the cable, click the display back into position and turn on. Appliance Relay stuck Incorrect (DC) transformer used Check the type of transformer used. If a DC output transformer has been used it can cause the relay to stick. Disconnecting then reconnecting the power should release the relay however if a DC transformer has been used this will continue to happen and damage the relay so an inrush limiting device must be added to protect the relay. 30 1300 368 631 | www.thermogroup.com.au Technical Data Supply voltage Maximum load UFH relay Appliance relay Temperature range Ambient Compatible sensors* Accuracy Warranty IP Rating Width Height Depth 230/240V 50/60Hz 20A combined 16A (3600W) 5A (1125W) 5 ~ 35°C 0 ~ 50°C 6.8K, 10K, 12K, 15K, 33K ±0.5°C 3 years IP30 129mm 88mm 48mm (31mm in wall) *All quoted sensor resistance ratings are measured at 25°C www.thermogroup.com.au | 1300 368 631 31 Service and Support Thermogroup PO Box 822 Leeton NSW 2705 AUSTRALIA Phone: 1300 368 631 Technical Line: 1300 989 464 www.thermogroup.com.au sales@thermogroup.com.au Watch the video guide on our website www.thermogroup.com.au
