Problem: The central unit does not respond to any of the buttons and none of the indicator lights are lit.
Solution: There is no power to the central unit. Make sure the power supply is properly plugged into the wall socket. Make sure the socket the power supply is connected to is live. 1: Check the fuses. 2: Check the connections on the contact. Make sure the power cable is properly connected to the central unit. The contact should be almost entirely inside the central unit. Due to the water-resistant design, the coupling is completely tight (applies only to Siro R). Make sure the power cable is properly connected to the Power supply. Ensure there is power in the kitchen: Check the fuses and connections in the consumption meter and check any home / away switches.

Problem: The central unit does not respond when specific buttons are used according to the instructions.
Solution: Error in the central unit. Component that needs to be replaced. Contact the retailer.

Problem: When you press two buttons simultaneously, the result is not as expected.
Solution: Holding down two buttons at the same time is a bit difficult. Carefully try again by first pressing Yes, holding down the Adjustment Mode button and then the Extra button.

Solution: The unit is defective. Press the OK button to find out the problem type from the indicator lights. Water leakage warning light flashes once: problem with the radio connection to the power supply unit. Water leakage warning light flashes twice: The power supply unit is defective. Water leakage warning light flashes three times: The power control unit has overheated. Stovetop hazard warning light flashes once: The sensor is defective. Stovetop hazard warning light flashes three times: The power supply is defective.

Problem: The installation does not go as expected.
Solution: You can restart the installation process at any time by pressing the Function Mode button for 5 seconds until you hear the signal, and then continue with installation step 3/6 (see Installation Instructions). Make sure the stove and oven (if connected to the power supply unit) are turned off before starting installation. Make sure the stove and oven are not live = that the breakers are off before you start the installation. Ensure there is power in the kitchen: Check the fuses and connections in the consumption meter and check any home / away switches.

Problem: The childproof lock alarm doesn’t work on any of the stove plates.
Solution: The wireless connection is not properly activated. Check the connection again: Repeat the installation from step 3/6.

Problem: The unit turns off the stove’s power, but then the power returns.
Solution: The power supply unit is plugged in incorrectly. Make sure the power supply unit is connected properly – in other words, the stove is connected to the output cable.

Problem: Problems with step 3/6 during installation.
Solution: The central unit does not search for a pairing signal, or the power supply unit does not send a pairing signal.

Problem: A wireless connection is not established.
Solution: The central unit searches for a pairing signal from the power supply unit only when the light is flashing purple-blue. The power supply unit will send the pairing signal for eight seconds when it is connected to the power grid. See installation step 3/6. Make sure the power supply unit is not powered before starting step 3/6: Switch off breakers in the fuse box. Hold down the Function Mode button for 5 seconds until you hear a signal and restart the installation process from step 3/6. There is no power to the power supply unit. Ensure there is power in the kitchen: Check the fuses and connections in the fuse box and check any home / away switches.

Problem: Problem in installation step 4/6 (Calibration).
Solution: During calibration, the stove does not use power. Calibration requires that the stove uses at least 300 W of power.

Problem: Does not recognize the stove / hob.
Solution: With an induction stove, use a compatible plate or suitable metal item. When calibrating a stove, turn on the largest cooker plate with maximum heat. Make sure the oven is actually switched on – not just the oven light or the fan. The stove or oven is not connected to the power supply unit. Make sure the stove is connected to the power supply unit. The central unit may have been wirelessly connected to the neighbour’s power supply device. Repeat the installation for both stove monitors again from step 3/6.
