3.3. Wiring Connections

WARNING: Electrical installation should be performed by a qualified professional. Ensure power is disconnected before making any wiring connections.

The thermostat provides potential-free contacts for connection to your heating or cooling system.

• COM (Common): Public terminal of the relay.
• NO (Normally Open): Connect for heating systems.
• NC (Normally Closed): Connect for cooling systems.

For Heating Systems: Connect the system's control wires to the COM and NO terminals.

For Cooling Systems: Connect the system's control wires to the COM and NC terminals.

3.4. Final Assembly

Once wiring and battery installation are complete, carefully align the front panel with the mounted back plate and snap it into place until it is securely fastened.

4. Operating Instructions

4.1. Power On and Initial Display

After battery installation, the thermostat will power on and display the current room temperature, set temperature, and time on the backlit LCD screen.

4.2. Operating Modes

The chronothermostat offers several operating modes:

• Automatic Mode: Follows the programmed schedule for temperature control.
• Manual Mode: Allows you to set a constant temperature that overrides the schedule until the mode is changed.
• Holiday Mode: Maintains a specific temperature for a set duration, ideal for when you are away.
• Anti-freeze Mode: Prevents temperatures from dropping below a critical point (e.g., 5°C) to protect pipes from freezing.

4.3. Setting Temperature

To adjust the desired temperature, rotate the dial on the front of the thermostat. The set temperature will be displayed on the screen, and the system will adjust to reach this target.

4.4. Programming Schedules

The device allows for hourly programming to define comfort and economy temperature settings throughout the day and week. Refer to the detailed programming section in the full manual for step-by-step instructions on setting custom schedules or activating the two predefined programs.

6. Troubleshooting

If you encounter issues with your KPS CONFORTLINE CRONO chronothermostat, consider the following common solutions:

• No Display/Power: Check if the batteries are correctly inserted and have sufficient charge. Replace batteries if necessary.
• Incorrect Temperature Reading: Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources. Allow time for the sensor to stabilize after installation.
• System Not Responding (Heating/Cooling): Verify all wiring connections are secure and correct according to the installation diagram (Figure 4). Check the operating mode to ensure it is not in an inactive state (e.g., Holiday mode when you expect heating).
• Programming Issues: Review the programming steps carefully. Ensure the current time and day are set correctly.

For persistent issues, please contact technical support.
