Frequently Asked Questions - FH11S GENERAL Life
How do I install the FH11S thermostat?
Turn off the power supply, remove the old thermostat, connect the wires to the FH11S terminals (typically L, N, and load), mount the base to the wall box, and attach the front unit. Ensure that the wiring matches your heating system. For safety, consult a qualified electrician if unsure.
How do I program the weekly schedule?
Press the 'P' or 'Menu' button to enter program mode. Select the day, then set the time and temperature for each of the 6 periods. The FH11S allows separate program settings for weekdays and weekends. Confirm each step with the OK button.
How do I switch between heating and cooling modes?
Use the system switch button on the front panel or in the menu. Select Heating, Cooling, or Auto. In Auto mode, the thermostat will activate heating or cooling based on your setpoint and room temperature.
What does frost protection do?
Frost protection keeps the room temperature above a minimum level (e.g., 5°C) to prevent pipes from freezing. The FH11S automatically activates frost protection when the ambient temperature drops below the set limit, even if the thermostat is in setback mode.
How do I reset the thermostat to factory defaults?
Press and hold the reset button (small hole) for 5 seconds using a paperclip, or navigate to Settings > Factory Reset in the menu. This will restore all default parameters, including the schedule and calibration.
Why is the display not working?
Check that the batteries are correctly inserted and have sufficient voltage. Replace them if necessary. If the display remains off, check the battery contacts and clean them gently. If the issue persists, the device may need servicing.
How do I adjust the temperature calibration?
Enter the advanced settings menu by pressing and holding the '▲' and '▼' keys simultaneously for 3 seconds. Select 'Calibration' and adjust the offset from -5°C to +5°C to match a reference thermometer. This ensures accurate temperature control.
Will my settings be saved when I change the batteries?
Yes, the FH11S has a non-volatile memory. All programs and settings are stored permanently and will not be lost during battery replacement, as long as you replace the batteries within a few minutes.
What type of batteries should I use?
Use two AA alkaline batteries (1.5V) or lithium batteries for longer life. Do not use rechargeable batteries, as their lower voltage may affect the thermostat's operation.
How do I enable the child lock?
Press the 'Child' button (or hold the 'Menu' key) for 3 seconds until the lock icon appears. To disable, repeat the same operation. The child lock prevents unauthorized modifications to the settings.
