13.3 AUXILIARY OUTPUT (ixF=AUS) 

The AUX output (if present and configured) will be enabled / disabled following the status of the relative 
digital input. 

13.4 ENERGY SAVING (ixF=ES) 

The energy saving mode will be enabled / disabled following the status of the relative digital input. 

13.5 EXTERNAL WARNING ALARM (ixF=EAL) 

It is used to detect an external alarm. It does not lock the regulation. 

13.6 EXTERNAL LOCK ALARM (ixF=bAL) 

It is used to detect any critical external alarm. It locks immediately the regulation. 

13.7 EXTERNAL PRESSURE ALARM (ixF=PAL) 

It is used to detect any pressure external alarm. This signal locks the regulation after detecting 

nPS

 events in 

the interval 

dxd

. 

13.8 EVAPORATOR FAN MODE (ixF=FAn) 

It is used to control the evaporator fan. 

13.9 REMOTE HOLIDAY MODE (ixF=HdF) 

It is used to force the holiday mode. 

13.10  REMOTE ONOFF (ixF=onF) 

It is used to switch ON and OFF the device remotely. 

13.11  LIGHT OUTPUT (ixF=LiG) 

It is used to control the light output. 

13.12  PULL DOWN (ixF=CC) 

It is used to force a cooling cycle. 

13.13  MOTION SENSOR DETECTOR (ixF=EMt) 

It is used to connect an X-MOD motion sensor. Please note that motion sensor can be connected only to the 
HOTKEY port, so digital input 2 must be properly configured. 

13.14  CHANGE CONFIGURATION (ixF=MAP) 

It is used to change the controller configuration.
