Table 10.2: Storage depth in hours and days
Changing channels reduces the current storage capacity by approximately 0.5 % per
configuration change.
If a Sunny Boy Control manages 50 devices, the preset settings (3 channels per de-
vice, 15-minute measuring interval) result in a storage depth of about 12 days.
