Frequently Asked Questions - FH25S GENERAL Life

How do I install the FH25S thermostat?

Turn off power to your HVAC system. Remove old thermostat, label wires, and connect them to the FH25S terminals according to the manual. Mount the base plate, attach the thermostat, and restore power. Follow the setup wizard for basic configuration.

How do I set the time and day on the FH25S?

Press the Menu button, navigate to Time/Date, and use the up/down arrows to set the correct time and day. Confirm by pressing OK.

How do I program a weekly schedule?

Press Menu, select Schedule. Choose a day, then set up to 4 time periods (Morning, Day, Evening, Night) with desired temperatures. Repeat for other days or copy a day’s schedule to others.

Why is my thermostat not turning on?

Check if batteries are installed correctly and have charge. For wired units, ensure power is on at the breaker and that the C-wire (common) is connected. Replace batteries if needed.

How do I switch between heating and cooling?

Press the Mode button repeatedly to cycle through Heat, Cool, Auto, and Off. The display will show the active mode.

What does the 'Low Battery' icon mean?

It indicates the batteries are low and need replacement. Replace with two fresh AA alkaline batteries to ensure proper operation. The thermostat will retain settings for a short time during battery change.

Can I use the FH25S with a heat pump?

Yes, the FH25S is compatible with most heat pump systems. In the installer setup, select the heat pump option and configure the reversing valve (O/B) as needed.

How do I reset the thermostat to factory defaults?

Press and hold the Menu and Up buttons simultaneously for 10 seconds until the screen resets. All settings will be cleared, and you’ll need to reconfigure.

What temperature range does the FH25S support?

The thermostat can be set between 5°C and 35°C in heating mode, and between 10°C and 37°C in cooling mode (typical). Exact limits depend on HVAC system.

How do I clean the FH25S thermostat?

Use a soft, dry cloth to gently wipe the surface. Do not use water, solvents, or abrasive cleaners, as they may damage the electronics.

ENGLISH

ROOM THERMOSTAT PLACEMENT

Place your Room Thermostat in a room you use frequently in your living space. For example; like the hall or living room of your home. Avoid installing the Room Thermostat in places where there is a lot of air circulation, such as at the doorway or by the window. Also, do not place it close to heating units (heater core, fireplace, etc.) and in direct sunlight. We recommend that the room thermostat is placed at a height of 150 cm from the floor.

ROOM THERMOSTAT TEMPERATURE CALIBRATION

Temperature sensors used in Room Thermostats are very sensitive. Based on the temperature on the thermometers in your living space you need to calibrate your Room Thermostat. For this:
- While your device is off, press and hold the button for 3 seconds.
- Press the button until you see the calibration menu that says "CFL" press it. The temperature difference you want from the calibration menu, Adjust by turning the button to the right or left. This value can be adjusted between "-8°C" and "+8°C".
- Press the button until the device turns off to save the settings and
exit.
- Note: Recommended temperature calibration setting is "0.0°C".

ROOM THERMOSTAT HEATING / COOLING MODES

Your Room Thermostat has heating and cooling modes. In order to switch easily between heating and cooling modes:

• While your device is turned off, press and hold the button for 3 seconds.
• Press the button until the "PU" menu appears.
• You can switch between HE" (heating) and Eo" (cooling) modes by turning the button to right or left in the Fu" menu.
• To save the settings and exit, press the button until the device turns off.
• The settings you have made have been saved. Once you turned on your device, it will operate with the changed settings.

ROOM THERMOSTAT HYSTERESIS POSITIVE MENU

The hysteresis positive factory setting of your Room Thermostat is 0.5^irc C. This value can be adjusted between "0.1^irc C" and "2.0°C". While the hysteresis positive value is 0.5^irc C, your Room Thermostat will send a command to your heating unit when the room temperature rises 0.5^irc C above the set temperature. For example, when we set the Room Thermostat to 22.0^irc C, your heating unit will stop when the room temperature rises to 22.5^irc C. To change the hysteresis positive setting:

• While your device is off, press and hold the button for 3 seconds.
• "Press the button until the HSP" menu appears.
• In the hysteresis positive menu, you can adjust the operating sensitivity by turning the HSP " button to the right or left.
• Press the button until the device turns off to save the settings and exit.
• The settings you have made have been saved. When you turn on your device, it will work with the operating sensitivity you have set.

ROOM THERMOSTAT HYSTERESIS NEGATIVE MENU

The hysteresis negative factory setting of your Room Thermostat is -0.5^ircC . This value can be adjusted between -0.1^ircC and -2.0^ircC . While the hysteresis negative value is -0.5^ircC , your Room Thermostat will send a command to your heating unit when the room temperature drops 0.5^ircC below the set temperature. For example, when we set the Room Thermostat to 22.0^ircC , your heating unit will work when the room temperature drops to 21.5^ircC . To change the hysteresis negative setting

• :While your device is off, press and hold the button for 3 seconds.
• Press the button until the HSn "menu appears.
• In the hysteresis negative menu, you can adjust the operating sensitivity by turning the H5n." button to the right or left.
• Press the button until the device turns off to save the settings and exit.
• The settings you have made have been saved. When you turn on your device, it will work with the operating sensitivity you have set.

FLOOR SENSOR TEMPERATURE SETTING MENU

If a floor sensor is installed with Room Thermostat, only GENERAL Life floor sensor should be installed. Otherwise, the product will be out of warranty.
*In case of floor sensor connected, the following settings apply. The factory temperature setting for floor sensor is 28°C. This value can be adjusted between 23°C and 34°C. The floor sensor operating sensitivity is 1°C. For example, when you set the floor sensor temperature to 28°C, your Room Thermostat will stop the heating unit from working when the floor temperature rises to 29°C. When the floor temperature drops to 27°C, it starts the heating unit of the Room Thermostat. To change the floor sensor temperature:
- Press and hold the button for 3 seconds while your device is off. - Press the button until the " menu appears.
- Adjust the operating temperature by turning the " button to the right or left in the floor sensor temperature menu that appears.
- Press the button until the device turns off to save the settings and exit.
- The settings you have made have been saved. When you turn on your device, it will operate at the floor sensor temperature you have set.

FACTORY RESET

You can reset the Room Thermostat to its factory default settings.
This action resets the calibration setting and hysteresis settings to the factory setting. To factory reset your Room Thermostat:
- While your device is off, press and hold the button for 3 seconds. - Press the button until the "S" menu appears.
- While in the "S _t " menu, turn the button to the right or left, select the "YS" option and press the button.
- Your device will turn off and reset to factory settings.

ROOM THERMOSTAT WORKING PRINCIPLE

Heating Mode

As soon as you energize your Room Thermostat, it will start working. Your room thermostat takes the average room temperature of last 40 seconds as basis. If the ambient temperature rises above the hysteresis positive temperature you set, your Room Thermostat turns off the heating unit, and if it drops below hysteresis negative temperature value, it turns on the heating unit. Thus, it is ensured that the ambient temperature remains within a certain range.
If the floor sensor measures temperature above 28^irc C, it turns off the heating unit.*
*External floor sensor is only active when it is connected.

Cooling Mode

As soon as you energize your Room Thermostat, it will start working. Your room thermostat takes the average room temperature of last 40 seconds as basis. If the ambient temperature rises above the hysteresis positive temperature you set, your Room Thermostat will start the cooling unit and if it drops below hysteresis negative temperature value, will stop the cooling unit. Thus, it is ensured that the ambient temperature remains within a certain range.

*External floor sensor is deactivated in the cooling mode.
