My son pressed too many buttons and it has caused our heater to lock itself. It is currently very cold, so we would appreciate any suggestions to help me unlock it.
If its Displaying a Little key Picture, all you have to do to unlcok it is Hold the Up and Down Button until the heater beeps and it will be unlocked.
Have you tried unplugging it(disconnect the power source) for several minutes then reconnecting the power? You may just need to reset the program.Hope this helps.
