Thanks to Owner-Manuals.com! This manual was exactly what I needed. As Amana was purchased by Maytag and later by Whirlpool, there was no way to receive it from their websites. I was lucky to find this resource.
Great to be able to set channels again, on an old but stoll fine working TV

De-icer control
Do not operate dehumidifier at temperatures below 18.3% (65°F). The coils may become iced over and unit will not operate properly. Your Whirlpool dehumidifier is equipped with a feature to help you get the most comfort from your new appliance by permitting it to operate down to 18.3% (65°F). If your dehumidifier runs when room temperature and humidity conditions are low, frost can form on its evaporator coil. This interferes with proper operation. The De-icer Control senses frost build-up on the evaporator coil and automatically shuts off the compressor. The fan continues to run, drawing air across the coil and melting the frost. When the coil is defrosted, the compressor is automatically restarted, and dehumidifying is resumed.
