3. Introduction Congratulations on the purchase of your new touch thermostat. We hope that you will enjoy the ease of use offered by the touchscreen and the intuitively designed user interface. You can program the thermostat in any way you would like with the options provided under Heating Schedule and User Settings. The thermostat features an adaptive function that automatically changes the heating start times to ensure that the required temperature has been reached at the beginning of any specific event.
4. General Operation The thermostat has two physical buttons. A ground fault (GFCI) test button is located on top of the thermostat, and a power/reset button is located on the right side of the thermostat. The GFCI should be tested monthly (all settings, including time and date, will be remembered). The thermostat is an intuitively operated touch thermostat in which the touchscreen is used to navigate through the menus and to change the settings.
4.1.Navigation Buttons Accept/Back/Cancel/Arrow Up/Arrow Down/Arrow Left/Arrow Right Whenever you change a parameter setting, you must tap the “Accept” button for the thermostat to acknowledge the change. “Accept” is shown on the screen as “√”. “Back” is shown on the screen as a button marked with a hollow arrow pointing to the left. In the various menus and submenus, you will find the “Back” button in the upper left corner of the touchscreen. Tap the “Back” button to return to the previous menu.
5. Ground Fault: (GFCI) 1/2 The GFCI thermostat has a built-in GFCI that ensures personal safety in case of ground faults. It is important that the GFCI is tested monthly. Installation and use must be according to the national and local regulations. Testing the GFCI: Press the “TEST” button. The test is successful if the red LED on the right of the thermostat flashes once every two seconds and “GROUND FAULT” appears on the display. If this does not occur, check the installation.
5. Ground Fault: (GFCI) 2/2 The red LED on the right of the thermostat can indicate four different GFCI states: 1. LED off – NORMAL state. 2. LED flashing slowly (once every two seconds) – TRIGGERED state. Try pressing the “Standby/Reset” button to reset the GFCI. 3. LED flashing quickly (five flashes per second) – ERROR state. Try switching the power off and then back on again.
