Solar controller XTDC - Sorel

Useful notes/tips and tricks
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. „6.2.6. - max. speed“ on
page 30). This saves electricity!
The service values (see „8. - Service values“ on page 44) include not only current measurement values and
operating states, but also all of the settings for the controller. Save the service values at least once after commissioning
has been successfully completed (see „6.22.4. - Save confi guration“ on page 42).
In the event of uncertainty as to the control response or malfunctions the service values are a proven and successful
method for remote diagnosis. Save the service values (see „8. - Service values“ on page 44.) at the
time that the suspected malfunction occurs. Send the service value table with a brief description of the error to
the specialist or manufacturer.
In programs with pools, the charging of the pool, e.g. for winter operation, can be switched off using a simple
function. 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.
To protect against loss of data, record any analyses and data that are particularly important to you (see 2.) at
regular intervals.
