Hello, For more information on how the ITC-308-WIFI works, please refer to. > [@Q&A: How does ITC-308WIFI work?](https://community.inkbird.com/t/q-a-how-does-itc-308wifi-work/151): > > ITC-308WIFI has a special temperature mode and a normal temperature mode. The trigger conditions for the special temperature mode are: Enter the setting mode through the SET key then exit. Enter the setting mode through the app then exit. In the special temperature mode, ITC-308WIFI will ignore the settings of HD (Heating hysteresis temperature) and CD (Cooling back temperature) and turn on the heating/cooling output. It will not enter the normal mode until the temperature reaches the SV tar… If its settings cannot be saved, please ensure that the ITC-308-WIFI remains connected to the network. Please provide the app you are using and a video of the problem to [support@inkbird.com](mailto:support@inkbird.com). --- _[View the full topic](https://community.inkbird.com/t/what-does-the-heating-hysteresis-setting-do-on-inkbird-itc-308-wifi/2879)._
