// 
// This script is activating the fan on output2 depending action on input button 1 
// 
// 
// Input  1: button, output 1 on/off 
// Input  2: ---
// Output 1: Lamp, timer switch off after 30 minutes
// Output 2: Fan,  timer switch off after 30 minutes 
// 
// 
// Case 1: Lamp OFF, Fan OFF 
//    Button short keypress: Lamp ON, delayTimer stopped, Fan OFF 
//    Button long  keypress: Lamp ON, delayTimer started, after delayTimer expired -> Fan ON 
// Case 2: Lamp ON, Fan OFF 
//    Button short keypress: Lamp OFF, delayTimer stopped, Fan OFF 
//    Button long  keypress: Lamp OFF, Fan ON 
// Case 3: Lamp OFF, Fan ON 
//    Button short keypress: Lamp ON, delayTimer stopped, Fan OFF 
//    Button long  keypress: Lamp ON, delayTimer started, after delayTimer expired -> timer switch off retriggered 
// Case 2: Lamp ON, Fan ON 
//    Button short keypress: Lamp OFF, delayTimer stopped, Fan OFF 
//    Button long  keypress: Lamp OFF, Fan ON, timer switch off retriggered  
// 
//
// Configuration script: 
// - delayTms: delay time till output 2 is activated
//
