1. A temperature and humidity controller operating at first mode, second mode, third mode, or fourth mode, comprising:
- a temperature unit having temperature sensing means, setable adjustable temperature setting means, and temperature switching means responsive to said temperature sensing means and temperature setting means to provide a connection between two terminals of said temperature unit for a temperature above said temperature set;
a humidity unit having humidity sensing means, setable adjustable humidity setting means, and humidity switching means responsive to said humidity sensing means and humidity setting means to provide a connection between two terminals of said humidity unit for a humidity above said humidity set;
means for displaying the temperature of surrounding air;
means for displaying the humidity of surrounding air;
a male receptacle to be connected to a conventional AC outlet for supplying a high AC voltage;
a transformer transforming said high AC voltage to a low AC voltage;
an AC/DC converter converting said low AC voltage to a low DC voltage;
a relay having first and second input terminals, first, second and third output terminals, closed switching means to provide connection between said first output terminal and said second output terminal when said low DC voltage is applied between said first input terminal and said second input terminal, and open switching means to provide connection between said first output terminal and said third output terminal when no voltage is applied between said first input terminal and said second input terminal;
means for connecting said low DC voltage to said first and second input terminals, controlled by said temperature switch means, when operating at said first mode or said second mode;
means for connecting said low DC voltage to said first and second input terminals, controlled by said humidity switch means, when operating at said third mode or said fourth mode;
a female receptacle for supplying said high AC voltage to a load;
means for connecting said high AC voltage to said female receptacle, controlled by said open switching means, when operating at said first mode or said third mode;
means for connecting said high AC voltage to said female receptacle, controlled by said closed switching means, when operating at said second mode or said fourth mode.
