2.10.9 Changing the maximum output (Hi) for CH
operation
The maximum output for CH operation can be changed with
parameter p 17 (maximum fan speed) and is set standard
to a speed of 2400, 3500 or 4600 rpm for the three System-
types. See the speed-input ratio figures.
This parameter can be changed from the stand-by status as
follows:
• Press the [enter]-key and briefly the [reset]- key until codes
c and 0 appear alternately in the display.
• Press the [+]-key until access code 12 is displayed.
• Press the [enter]-key until p1 appears (codes p [ and
[ 1 are displayed alternately);
• Press the [+]-key to go to parameter 17.
• Press the [enter]-key until p17 appears (codes p [
and 17 are displayed alternately);
• Press the [+] or [-]-key to change this value for Avanta 18v,
for example to 35 (3500 rpm corresponds with 18kW).
• Press [enter]-key to confirm the value.
• Press [reset]-key to return to the operating mode.
