See page 21 - 23. 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. 20 1300 368 631 | www.thermogroup.com.au Advanced Settings Adjusting the advanced settings To access the settings, switch the unit off by pressing .

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. Check whether there are any high temperature influences around the thermostat or the floor sensor probe. High temperature influence Faulty floor sensor Incorrect Settings 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* 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 22. 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 units compared to the defaults listed on page 22. 26 1300 368 631 | www.thermogroup.com.au Troubleshooting Guide Problem "Er" error message 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 or the thermostat set to ambient. See page 22. Need a hand?
