PowerFail Detection is identifying power failures
and saving all relevant data before the voltage
drops below a critical level.
In a few cases of exception data cannot be
saved. The next time the control unit is switched
on, the display then shows E81 and the control
unit clicks three times. A manual reset must be
performed to rectify this fault (see Section 7.4.4).
8.2.3 Control unit click codes
As soon as the control unit is supplied with power, it uses the
built in relays to generate acoustic signals informing the user
of system status as well as of the reason for the last shutdown.
The table below shows the number of clicks generated and the
information they provide.
