A typical cleaning interval for aeration basins would be 2 hours (120 minutes).
In colder climates, condensation may form and then freeze in the tubing. This
can be prevented by setting the interval to 5 - 20 minutes.
The cleaning time would typically be 30 seconds.
The measurement delay (recovery time) may also be used to coordinate with
other processes. The delay merely freezes the last reading before cleaning
begins. A typical value would be 60 seconds.
