Frequently Asked Questions - FH26S GENERAL Life
How do I set the temperature on my GENERAL Life FH26S thermostat?
Press the '+' or '-' buttons to adjust the desired temperature. The current set temperature will flash on the display. After 5 seconds, the setting is saved automatically.
How can I program the weekly heating schedule?
Press the 'P' button to enter programming mode. Use '+' and '-' to set the time and temperature for each of the 6 periods. Select the day or day block you want to program and confirm with 'OK'. The thermostat allows individual settings for weekdays, weekends, or each day separately.
What batteries does the FH26S thermostat need?
To power the thermostat, insert two AAA 1.5V alkaline batteries into the compartment on the back of the device. To replace the batteries, remove the front cover, take out the old batteries, and insert new ones while respecting polarity.
How do I reset the thermostat to factory settings?
Press and hold the 'Reset' button (located in the battery compartment) for 5 seconds. The display will show the default settings again. This operation erases all custom programs and temperature settings.
Why is my thermostat display blank?
First check if the batteries are correctly installed and have sufficient charge. If the screen remains blank, replace the batteries. If the problem persists, the internal fuse or relay may be defective. Contact a qualified technician for repair.
Can I use the FH26S for electric floor heating?
Yes, the FH26S is suitable for controlling electric heating systems, including floor heating. It switches the heating load via a relay rated for up to 16A. Make sure the total load does not exceed the specified maximum power.
What is the temperature swing or hysteresis?
The default hysteresis is ±0.5°C. This means that when the set temperature is reached, the heating switches off, and it switches on again when the temperature drops by 0.5°C below the set value. This prevents rapid on/off cycling.
How do I lock or disable the child lock function?
To activate the key lock, press and hold the '+' and '-' buttons simultaneously for 3 seconds. The lock symbol will appear on the display. Repeat this operation to unlock. This prevents accidental changes to the settings.
What is the temperature sensor calibration?
If the displayed temperature differs from the actual room temperature, you can calibrate the sensor. In the advanced setting menu, look for 'Cal' or 'Offset' and adjust the value in steps of 0.1°C to compensate for reading errors.
Does the thermostat need a neutral wire?
The FH26S is battery-powered and does not require a neutral wire. The relay output is a dry contact, so you only need to connect the switching wires (live and load) to the terminal block. However, the heating equipment itself must be properly connected to the mains.
