Question 3

How to turn off the REGENT THERMODYNAMIQUE ECO 250L temperature regulator?

Accepted Answer

To turn off the REGENT THERMODYNAMIQUE ECO 250L, simply press the ON/OFF button located on the control panel. The screen will display "OFF", the SMILE LED will turn off, and all other indicators will turn off.

Important: When the device is turned off, the corrosion protection remains automatically active thanks to the active current titanium anode and the magnesium anode. The device enters frost protection mode: the water temperature inside the tank is maintained above 5°C to prevent damage from potential exposure to freezing.

If you have an anti-legionella function activated in the installer menu (which is optional), it will continue to run according to its monthly cycle even when the device is turned off, heating the water once a month to 65°C for a maximum of 15 minutes.

For a prolonged absence, you can also use the TRAVEL mode by pressing the "mode" button several times until you select this option, then programming the number of days of absence. During this period, the device remains off but the corrosion protection and frost protection mode remain active. The device will automatically reactivate after the specified number of days.

Question 4

Where are the buttons and controls on the REGENT ECO 250L control panel?

ON/OFF Button: turns the device on and off
MODE Button: selects the operating mode (AUTO, BOOST, GREEN, TRAVEL)
Central Dial: adjusts the temperature and allows navigation through information and configuration menus

Above is the screen displaying the set temperature, the measured temperature, as well as indications on the operating mode, any faults, and the status of the device.
