How do I adjust the dial on the ATLANTIC water heater to get hotter water?

Question

Accepted Answer

To increase the water temperature of your ATLANTIC Chaufféo water heater, you need to adjust the potentiometer (dial) of the electronic thermostat located inside the protective cover of the water heater. This thermostat controls the heating of all the water contained in the tank.

Location and access: Unscrew the fixing screw of the protective cover located on the side of the water heater to access the thermostat. Inside the cover is the connection label with the adjustment diagram. You will find the potentiometer numbered with positions generally ranging from 1 to 7.

How to adjust: Turn the potentiometer to the right (clockwise) to increase the water temperature. The factory setting of the ATLANTIC Chaufféo water heater is position 5, corresponding to approximately 65°C. To obtain hotter water, turn it to position 6 or 7. After making the adjustment, carefully close the cover and screw the fixing screw back in.

Action time: Be patient: after adjusting the potentiometer, you will need to wait several hours (generally 4 to 8 hours depending on the capacity of your tank) for the water to reach the newly programmed temperature. Test the water at the hot water tap to check that it meets your expectations.

Attention to safety limits: For safety and energy-saving reasons, do not set the temperature too high. For bathrooms, the maximum temperature should be 50°C at the draw-off points. For other rooms (kitchen, etc.), it should not exceed 60°C. A setting that is too high increases the risk of burns and consumes more electricity.

If you are unsure about the setting, consult the technical label located inside the cover of the water heater that indicates the correspondences between each numbered position and the temperature in degrees Celsius.
