The
service values
(see 15.) include not only current measurement
values and operating states, but also all of the settings for the con-
troller. 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
diagnosis. Write the service values down (see 15.) at the time that
the suspected malfunction occurs. Send the
service value table
by fax or e-mail with a brief description of the error to the specialist
or manufacturer.
The controller provides the option of switching the
heating circuit
pump
depending on the outdoor temperature (summer/winter
changeover) or when the reference value is undershot or overshot.
(see menu 12.7.6).
To protect against loss of data, record any
statistics
and data that
are particularly important to you (see 7.) at regular intervals.
The
operating hours
displayed in the „Statistics“ menu should only
take into account the actual operating time of the compressor. In
order not to take into account any times in which the heat pump is
blocked, e.g. by a mains disconnect, the controller compares the
glycol
fl
ow temperature with the glycol return temperature to check
whether the compressor is actually switched on.
The remote adjuster
RT21
, which can be connected as an option,
can be used from the living space to carry out a parallel translation
of the heating characteristic, thus affecting the living space tempe-
rature quickly and easily.
Ask your power utility what their
low-rate periods are.
To save
operating costs, the controller provides the option of carrying out in-
creased storage tank charging at certain times (see 8.4 and 8.6).
