Nothing happend because config events switches outs when the signal exceeds the setpoint + hysteresis and next setpoint- hysteresis.
In this case you have set point 17+ 0,6 hysteresis, if temp was below 17-0,6 (=17,6, then out0 OFF.
But if temp was above 16,4 (eg. 16,8) and next go to >=17,6, nothing hapend because temp never was below 16,4.
