9.2 Remote display
Read the system information from the remote display as
follows:
1. Press the menu button briefly to call up the current infor-
mation from the monitoring unit.
The antenna symbol disappears briefly and then the cur-
rent value of the first parameter is displayed.
2. Press the menu button again within 10 seconds to display
the current value of the next parameter. The parameters
are described in the table at the end of this section.
Observe the following points when operating the unit:
• If the menu button is not pressed then new information
is called up every 1o minutes. This can also be recognised
by the brief disappearance of the antenna symbol.
• When the menu button is pressed and held for 5 sec-
onds the remote display calls up new information via the
system configuration. The display sequentially shows the
number of irradiation sensors, the number of tempera-
ture sensors and the number of inverters (inverters that
are nor active or are in Standby , e.g. due to inadequate
irradiation, are not included).
• When the system does not contain any irradiation and/or
temperature sensors then the corresponding menu set-
tings are skipped.
• The battery symbol flashes when the battery voltage
drops below the nominal value. When this occurs, the
batteries should be replaced within the next 3 months.
After the batteries have been replaced, the remote display
must be restarted as described in Initial commissioning .
• The kWh/day meter starts running as soon as the sys-
tem is operational. The weekly and monthly meters are
incremented each evening by the total energy generated
on the respective day. The year meter is incremented once
a week by the total energy generated in the respective
week.
• When the respective period expires, e.g. 7 days for the
week, 30 days for the month and 52 weeks for the year,
the relevant old information is deleted so that the run-
ning totals are always correct for each respective period.
• Since the annual total is not updated until the end of a
week and the weekly and monthly totals re updated at
the end of each day, the value displayed for the annual
total may initially be smaller than the weekly or monthly
total.
