2. The following only applies to
commissioning in summer
(cooling mode):
Press
repeatedly unto the LED
below symbol "
" (cooling mode)
illuminates (see page 27):
The LED next to symbol " "
(compressor) flashes.
The compressor starts after a
start-up delay of 6 minutes (stan-
dard setting).
Note
Should the unit fail to start, observe
the LED indicators on the phase
monitor (see page 39).
The unit is operational.
Adjusting parameters HEA and H31
1. Disable the heating curve; for this,
set parameter H31 to "0".
Note
For a description of the adjustment
of parameters and the code, see
from page 35.
Adjusting the throughput in the hydraulic circuit
The pump rate of the internal pump of
the hydraulic circuit can be adjusted
to ensure the required minimum
throughput. This is made in accor-
dance with the system pressure drop
via the three-stage speed selector of
the pump. In the delivered condition,
the pump is set to the highest stage
(3).

3. The following only applies to
commissioning in winter
(heating mode):
Press
repeatedly unto the LED
below symbol "
" (heating mode)
illuminates (see page 27):
The LED next to symbol " "
(compressor) flashes.
The compressor starts after a
start-up delay of 6 minutes (stan-
dard setting).
Note
Should the unit fail to start, observe
the LED indicators on the phase
monitor (see page 39).
The unit is operational.
2. Raise the return temperature; for
this, change parameter HEA (see
page 36).
As the units are reverse controlled,
select a value approx. 5 °C lower
than the required flow temperature.
For the required heating and cooling
water throughput, see the specifica-
tion (from page 48).
