3.3 Wiring Instructions
The Tybox 1127 is a wired, mains-powered unit requiring a 230 Volts electrical supply. Connect the thermostat directly to your heating system according to the specific wiring diagram provided in the product packaging. Ensure all electrical connections are secure and properly insulated.
Note: While product specifications may mention Wi-Fi connectivity, the Tybox 1127 is primarily a wired thermostat for direct control of your heating system. Any Wi-Fi functionality, if present, would typically be for remote monitoring or smart home integration, and specific setup instructions for such features would be detailed in supplementary documentation.
4. Operating Instructions
4.1 Basic Operation
The thermostat features a central selector dial and several push-buttons for navigation and setting adjustments. The digital display shows the current time, ambient temperature, and the active operating mode (indicated by a sun icon for comfort mode and a moon icon for economy mode).

4.2 Programming Your Schedule
The Tybox 1127 allows for weekly programming, customizable in half-hour increments.
- Rotate the central selector to the 'Program' position.
- Use the navigation buttons to select the day and time segment you wish to modify.
- Set the desired temperature for each half-hour segment, choosing between comfort (sun) and economy (moon) modes.
- Repeat for all days and time segments as needed.
- Confirm and save your program settings.
4.3 Heating Anticipation Function
This intelligent feature continuously learns your home's thermal characteristics and external conditions. It calculates the optimal time to activate your heating system to ensure your desired temperature is reached precisely at the programmed time, compensating for system inertia.
4.4 Temporary Override
If you need to temporarily deviate from your programmed schedule, use the override function. This allows you to set a new temperature for a specific duration, after which the thermostat will revert to its programmed settings.
4.5 Absence Mode
For extended periods away from home, activate the absence mode. This mode maintains a lower, energy-saving temperature. You can specify your return date, and the thermostat will automatically resume your normal heating program in anticipation of your arrival.
5. Maintenance
The Delta Dore Tybox 1127 is designed for minimal maintenance.
- Cleaning: Clean the thermostat casing with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the unit.
- Air Vents: Ensure that the thermostat's air vents are not obstructed by dust or objects, as this can affect temperature sensing accuracy.
- Internal Components: There are no user-serviceable parts inside the thermostat. Refer any internal servicing or repairs to qualified personnel.
