Startup response
The application is restarted after every reset, so that all the connected motorized valve actuators are synchronized (see section 3.7).
Startup delay
After a reset, it takes up to 5 minutes for all the connected room thermostats to restart. This is designed to avoid overloading the mains power supply when restarting. At the same time, it reduces the load on the KNX network, as not all thermostats transmit data at the same time. The delay (TWaitDevice) is determined by the thermostat's device address. After the delay, the device starts to send.
