3.1.11 Condenser
fans
If a condenser probe is available, an AUX output can be confi gured to manage the condenser fans by setting
H1,H5,H10 = 6.
The condenser fans are activated based on the settings of parameters
F4
and
F5
.
After the compressor starts the fi rst time the condenser fans are activated at
F4+0.2
degrees so as to
compensate for rapid increases in temperature that cannot be easily read by the probe. Subsequently, the fans
are activated and deactivated at
F4+F5 and F4
.

Note:
if no condenser probe is selected, the
condenser fan output is deactivated.
If no condenser probe is available, the condenser
fans can be controlled by setting H1,H5,H10 =12
and c11=0.
