ASFnominal:
The recommended ASF = 0.9 for installations with a single aerothermal unit and ASF = 0.45 for installations with two aerothermal
units, regardless of the ecoGEO model installed and whether the installation is aerothermal or hybrid.
An ASF that adjusts more closely to your specific installation. To do so, operate the heat pump to start generating heat (DHW,
heating or pool) at sufficient power for the fan to be operating at the full speed setting (the speed can be checked at any time in
the user menu/information). Once this is done, make sure there is no frost or dirt on the AU12 unit. Read the nominal ASF value of
the installation in the user menu/information. Configure the control with the setting obtained.

Aerothermal collector
Min Max
40 70% 1. Used to adjust the maximum and minimum fan speed percentage allowed. The
recommended minimum is 40% and the recommended maximum is 70%.
4.0C
0.45
2. Used to adjust the difference in air-antifreeze agent target temperatures to control
the fan. The recommended temperature setting is 4ºC.
3. Used to adjust the nominal operation factor (ASFnominal) of the aerothermal
collector.
Defrost

1. Used to adjust the defrost program of the aerothermal collector and to adjust its
parameters.

2. Used to adjust the production system used as a heat source to perform defrosting
12.0C
20min
(heating / DHW / pool). Remember that heat will be diverted from this system to
defrost, so its temperature will drop slightly.
3. Used to adjust the deviation with regard to the ASFnominal that the defrost program
starts up with. The recommended setting is 50%.
4. Used to adjust the brine fluid temperature required to finish the defrost program.
The recommended temperature setting is 12ºC or above.
5. Used to adjust the maximum defrost program operation time. The recommended
time setting is 20 min.
Hybrid system
20%
1. Used to adjust the minimum power percentage absorbed by each collector. If the
20%
power percentage absorbed by one of the collectors decreases below the established
limit, it is disabled. The recommended initial setting is 20%; however, these settings
12.0 C
must be adapted to the type of geothermal collector and its limitations.
2. Used to set a minimum input temperature for the geothermal collector; below this
temperature, the geothermal collector will be disabled. This option is useful for
disabling horizontal brine systems when they are blocked, thereby assisting in their
recovery.
Note: This screen is only available for hybrid brine systems.
