Instead of setting the fl ow rate for the system using a fl ow rate limiter,
it is better to adjust the fl ow rate using the switch on the pump and by
means of the “max. speed” setting on the controller (see 7.9.4). This
saves electricity!
The service values (see 9.) include not only current measurement val-
ues and operating states, but also all of the settings for the controller.
Write the service values down just once after commissioning has been
successfully completed.
In the event of uncertainty as to the control response or malfunctions
the service values are a proven and successful method for remote diag-
nosis. Write the service values down (see 9.) at the time that the sus-
pected malfunction occurs. Send the service value table by fax or e-mail
with a brief description of the error to the specialist or manufacturer.
In program 13 “Solar with storage tank and pool” the charging of the
pool, e.g. for winter operation, can be switched off using a simple func-
tion. To do this, simply press and hold the “esc” key down for several
seconds on the diagram/overview screen. A message appears on the
display as soon as the pool is switched off or when the pool is switched
on again.
The Operating hours displayed in the “Analysis” menu are solar oper-
ating hours. This therefore only takes into account hours in which the
solar pump is active.
To protect against loss of data, record any analyses and data that are
particularly important to you (see 2.) at regular intervals.
