6. Programming Features
The Sokio radiator includes advanced features for energy efficiency and convenience.
6.1 Customizable Daily Programming
In Prog Mode, you can set a personalized heating schedule for each day of the week. Refer to the detailed programming section in the full manual (if available) or the on-screen prompts for step-by-step instructions. This allows you to define specific temperatures for different times of the day.
6.2 PIN Code Lock
To prevent unauthorized changes to settings, the controls and parameters can be locked using a PIN code. Access the settings menu (usually by holding a specific button) to set or activate the PIN lock feature. This is particularly useful in households with children or in public spaces.
6.3 Window Open/Close Detection
The radiator is equipped with a sensor that detects when a window is opened. If a sudden drop in temperature is detected, the radiator will temporarily reduce its heating output to save energy, preventing unnecessary heating of cold incoming air. Heating will resume once the window is closed or after a set period.
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your radiator.
7.1 Cleaning
- Always disconnect the radiator from the power supply before cleaning.
