- Program Button (P): Used to enter and exit programming mode.
- Function Buttons (Right Side): Buttons for power, time/date settings, and other functions.
- Rotary Dials (Bottom): Used for quick temperature adjustments or setting specific values during programming.
5.2. Setting Time and Date
To adjust the current time and date:
- Press the Time/Date button (often indicated by a clock icon).
- Use the rotary dials or arrow buttons (if present) to adjust the hour, minute, day, month, and year.

5.3. Programming Weekly Schedule
The chronostat allows for weekly programming to optimize energy consumption. This typically involves setting different temperature levels for various times of the day and days of the week.
- Press the P (Program) button to enter programming mode.
- The display will show the current day and a time slot. Use the navigation buttons or dials to select the day and time period you wish to program.
- Adjust the desired temperature for that period using the rotary dials.
- Repeat for all desired time slots and days.
- Press the P button again to save the program and exit programming mode.
5.4. Mode Selection
The chronostat offers various operating modes:
- Automatic Mode: Follows the programmed weekly schedule.
- Manual Mode: Maintains a constant temperature set by the user, overriding the program.
- Comfort Mode: Sets a higher, comfortable temperature.
- Economy Mode: Sets a lower, energy-saving temperature.
- Anti-freeze Mode: Maintains a minimum temperature to prevent freezing (e.g., 5°C).
Press the mode selection buttons on the left side of the unit to cycle through or select the desired operating mode.
5.5. Temperature Adjustment
In Manual, Comfort, or Economy modes, you can adjust the target temperature using the rotary dials at the bottom of the unit. Turning the dial clockwise typically increases the temperature, while turning it counter-clockwise decreases it. The new target temperature will be displayed on the screen.
6. Maintenance
6.1. Battery Replacement
When the battery low indicator appears on the display, replace the batteries promptly to ensure continuous operation. Follow the steps outlined in Section 4.1. Battery Installation. It is recommended to replace both batteries simultaneously with new, high-quality 1.5V AA alkaline batteries.
6.2. Cleaning
Clean the chronostat's exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the unit, as this may damage the surface or internal components.
