1. Setting the Time and Date

Upon initial power-up or after battery replacement, you may need to set the current time and date. Refer to the full product manual for specific button sequences to enter the time/date setting mode.

2. Selecting Operating Modes

Press the Mode button (usually indicated by a symbol or text) to cycle through the available operating modes:

• Auto: Follows the programmed schedule.
• Manual: Maintains a constant temperature set by the user, overriding the schedule.
• Holiday: Sets a reduced temperature for a specified duration, ideal for energy saving when away.
• Temporary Override: Allows a temporary temperature adjustment without altering the main program. The thermostat will revert to the schedule at the next programmed event.
• Off (Frost Protection): Turns off heating but activates if the temperature drops below a set frost protection level (e.g., 5°C) to prevent pipes from freezing.

3. Programming the Schedule (7-Day)

The thermostat supports a 7-day programming schedule with up to 6 independent time and temperature settings per day. This allows for customized heating patterns to match your weekly routine.

1. Enter programming mode (refer to the full manual for specific button presses).
2. Select the day or group of days you wish to program.
3. Set the desired time and temperature for each of the 6 available periods.
4. Repeat for other days as needed.
5. Save and exit programming mode.

The large backlit display will show the current time and temperature, making it easy to monitor your settings.

Maintenance

• Cleaning: Wipe the thermostat's exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Battery Replacement: Replace batteries annually or when the low battery indicator appears on the display. Use only LR6 AA 1.5V alkaline batteries.
• Disposal: Dispose of old batteries and the thermostat responsibly, following local regulations for electronic waste.
