Do not signal power on reset in case of a "warm" reset: The RTE signaled at every startup a coldstart to the firmware causing a reset of the button responsitivness to default. Even for example after a firmware update. The reset of the values is a wanted behavior in case a value was set which makes it impossible to operate the buttons. This is still possible by removing the battery => real cold start
