Yes, the Nautilus (IW60) has two ways of protecting it from freezing:
Mechanical: Freeze Protection Valve which has a thermo-plastic valve that reacts to cold water and starts to shrink at 39° F allowing the movement of water out the drain.
Electrical: The electrical freeze protection is the Module Board. With both gas and electric turned on, the board will receive a temperature reading from the inlet temperature sensor and will automatically turn on the unit when it recognizes 39° F. If the RV is to be stored for the winter, the Nautilus should be drained of all water.
