• Page 4: Description of buttons and functions Show support information by long pressing both button 1 and button 4 simultaneously for 3 seconds. Adjust and navigate down. Adjust and navigate up. Select and accept. When screensaver is active, press to wake up display. GFCI test button. Multifunctional button: Press once to go into standby mode or turn on the thermostat. When display is ON, hold for 15 seconds to perform a factory reset. Reset/confirm GFCI test mode. Heating: The LED lights up orange during heating.
• Page 5: Start-up wizard When the thermostat has been installed and turned on for the first time, or after a factory reset, the thermostat will run a start-up wizard. The wizard guides you through a basic setup process to ensure that you have the right settings and a thermostat test is performed. The start-up wizard gives you the option to adjust four settings, followed by the GFCI test. The dots in the left column show the setting number to help you navigate your way through the guide. The start-up wizard takes you through the following steps: unit, sensor application, floor protection, GFCI test. After the last setting, you will be instructed to perform a GFCI test. Once the test has been passed, the thermostat is ready to use. To see a description of the setting, you can tap the text or wait 10 seconds. If the default settings are fine, you can proceed to the GFCI test step immediately to complete the initial setup.
• Page 6: Start-up wizard During power-up, a pulsating select/accept button will appear, followed by the text “PRESS HERE.” Pressing this area will initiate the start-up wizard.
• Page 7: Start-up wizard Step 1 – Unit The first step is the Unit setting. In the Unit setting, the temperature unit can be set to F (Fahrenheit) or C (Celsius). Fahrenheit is set as default. Press the up or down arrow to set the temperature unit to Fahrenheit or Celsius. Press the select/accept button to change the setting. Press the select/accept button to confirm the setting.
• Page 8: Start-up wizard Step 2 – Sensor application The second setting option is the sensor application. You can choose between room sensor, floor sensor, or room sensor with floor limit. Once the sensor application has been chosen, you can only change it via the app or by performing a factory reset. With the floor setting, the floor sensor controls the heating system. With the room/floor protection setting, the room sensor controls the heating while the floor sensor limits heating according to set limits. With the room setting, the room sensor controls the heating system. With the sensorless setting, the thermostat can be set to a fixed heating percentage without any temperature sensor. The floor protection will be disabled in sensorless mode. Press the up or down arrow to scroll through the sensor options.
• Page 9: Sensorless mode is a regulation mode in the thermostat that allows selection of a heating percentage without a temperature sensor. This mode is selectable only during the initial setup wizard. Sometimes neither floor mode nor room mode is suitable for regulating heat in the floor. The thermostat is set to a fixed heating percentage of the cycle time. It is recommended to have a setting of 20-25% as a starting point. When sensorless mode is activated, the heating indicator will be off and will only light up when heating is activated. The screen will show the number in percent instead of the actual temperature in sensorless mode. There will be no floor overheat protection enabled when sensorless mode is selected. Internal overheat protection of the thermostat remains active in sensorless mode.
• Page 10: Start-up wizard - step 3: floor protection. The third setting option is the floor protection setting. Set the floor protection according to the floor type: W (wood), L (laminate), T (tiles) or OFF. Wood is the default setting. Once the floor type has been selected and the start-up wizard has been completed, you will only be able to change the floor type by performing a factory reset. Press the select/accept button to change the setting. Press the up or down arrow to scroll through the protection options. Press the select/accept button to confirm the setting.
