2.5 Start-up benets
2.5.1 Automatic start-up test
The installation is started up automatically, therefore considerably reducing the time required for the process.
There are the following types of start-up:
•  Test run and identication of the units forming the system.
•  Test run from the remote control.
•  Test run from the outdoor unit.
Test run and identication of the system units
The automatic test run can be activated through outdoor unit
DIP switch or indoor unit remote control switch. The outdoor unit
7-segment display gives all the information needed to check the
system is operating correctly.
The units forming part of the system are identied separately for 
the outdoor and indoor units:
•  Outdoor  units: Using the remote  control,  the  series  to  which 
each of the operational outdoor unit belongs (for example, sim-
ple or multiple series) can be assigned.
•  Indoor units: Using the rotary and DIP switch on each unit.
Test run from the remote control
The remote control can run 3 operations.
•  Auto-diagnostic: quick check of the operating conditions of the
indoor units and the outdoor unit.
•  Data memory query: if an abnormality occurs, the LCD remote 
control switch shows an alarm code and saves all the opera-
tion settings of the unit at the time the fault occurs, so that a 
quick diagnosis can be made of the installation.
•  Optional function setting: the remote control switch allows can-
cellation of the 4-degree offset in the heating mode and an
increase in the fan speed setting, among 29 possible options.
 This way, multiple indoor units can be set at the same time. Also, the conguration can easily be changed, even after the 
installation has been completed.
Test run from the outdoor unit
 The outdoor unit PCB is equipped with a 7-segment display, which depending on the position of the PSWs shows the fol-
lowing parameters in sequence.
•  Outdoor temperature.
•  Discharge gas temperature.
•  Evaporation temperature in heating mode.
•  Condensing temperature.
•  Discharge pressure.
•  Compressor run time.
This allows quick and accurate diagnosis of the installation during normal operation or test run.
2.5.2 Service verication
System operation control
The working order of the system is continuously monitored through the control system. All operating parameters that the
system uses to manage the outdoor and indoor units are continuously supervised.
