Relentless delivered by carrier, beautiful build quality, serious product: Bought to replace an older dehumidifier half as powerful (250watts, 2litres tray ...) by cons: - The former was much quieter inaudible from the ground chased - This can only work at night (slept on the 1st floor). - Former programmer working with the EDF peak hours (including holidays: water tray full return every time !!) - The new is not programmable, every night I have to put a delayed start at 1:15 ET stop it when I get up in the morning !!!!! - For vacation? I think of a continuous operation ... but beware the electricity bill! - Caution Do not touch the setpoint Factory setting 30% moisture, otherwise it hardly dehumidify! - With the old when the humidity was reached sarrêtait it (with a tempo on ventilation) then he never stops without any action on your part, only the compressor stops when the level is reached (it it's a shame!) ..... During the holiday he will turn 24/24 with his big fan !!!!! So we have to think before you buy to see if this is the product for you!
