A Bell Controller checks-in to OneVue hourly. You can optionally initiate a manual check-in. During each check-in, any pending schedule or setting updates are downloaded to the device, its current operating status and event history is sent to your OneVue account, and its time is synchronized with its NTP time source.
Press and release the device check-in button .
The device emits a series of audio beeps indicating its connection sequence. If a check-in fails, all data is stored in its non-volatile memory.
