Question 1

What does a turned-off LED on the ATLANTIC pilot wire wall box mean and how can I resolve this issue?

Accepted Answer

A turned-off LED on your ATLANTIC pilot wire wall box may indicate several situations related to the power supply or the operation of the device. Here are the main possible causes and the steps to diagnose and resolve this issue:

1. Checking the power supply

Ensure that the box is properly powered.
Check the circuit breaker or fuse associated with the box and verify that they are not tripped or blown.

2. Checking electrical connections

Inspect the cables and connections of the box for any loose, disconnected, or damaged wires.
Poor contact may prevent proper power supply and turn off the LED.

3. Checking the thermostat or associated controls

If the box is controlled by a thermostat or another control system, ensure that it is functioning and properly set.
A fault in the thermostat may prevent the box from activating and thus the LED from lighting up.

4. Resetting the box

Unplug the box for a few minutes, then plug it back in to attempt a reset.
This operation may resolve some temporary malfunctions.

5. Professional intervention

If after these checks the LED remains off, it is recommended to contact ATLANTIC customer service or a qualified electrician for a thorough diagnosis and possible repair.

Question 2

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

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.
