6. Check rotating field of compressor - with correct rotating field and
voltage on all three phases, there is no message on display.
7. When the message F016 failure phase rotating field appears on
display, check first if all three phases have voltage. If this is the
case, interchange two phases at the terminal blocks in the terminal
to reverse the rotating field.
8. Finally, turn ON LS switch for electric heating
Risk of total loss!
Repeated restart of heat pump can result in total loss!
In case of heat pump failure, an inspection by qualified and authorised per-
sonnel must be performed before restart
Info: Controller settings must only be performed during initial startup of ma-
chine.
This is not required for restart, since the settings have been saved (settings
remain saved even in case of power failure).
Info: During initial start-up, the specified limits are often exceeded, thus
numerous warning messages could appear.
For this reason, the warning messages occurring during this period can be
disabled by service personnel, see
Operating manual for heat pump con-
troller
.
After completing installation and wiring and tubing of indoor and outdoor
units, check for refrigerant leaks, loose power supply or control wiring,
wrong polarity, and ensure that no single phase in the power supply is dis-
connected.
Compressor will not operate unless the power supply phase connection is
correct.
11.3 Control of entire operation
This heat pump is equipped with an efficient electronic control system. All
necessary settings and options are described in the operating manual of
the controller.
Tip: The correct use of the controller saves money. Particularly the correct
settings of flow temperature, hot water temperature, heating curve and
heating times can result in substantial cost savings.
