    ADVANCED FUNCTIONS 1.- REMOTE ON/OFF This function allows you to turn the unit on/off by a simply remote contact (contacts 95-96 in AIRCOOLAIR /COMPACTAIR / FLA- TAIR units;contacts 88-89 in AIRCUBE units). Close contact = ON; Open contact = OFF. 2.- REMOTE CHANGEOVER WINTER/SUMMER On heat pump units (also in Aircoolair / Compactair / Flatair cooling only + electrical heater), cooling or heating mode can be selec- ted by a remote contact (contacts 97-98 in Aircoolair and contacts 95-98 in Compactair and Flatair).

    Given the growing and unstoppable trend towards Building Automation, the Climatic 40 controller offers the possibility of commu- nicating with Building Management Systems (BMS) via Modbus protocol. The Modbus standard interface is integrated into the control, so you do not need any sort of gateway, router, etc.

    ADVANCED FUNCTIONS 5.- LOW NOISE Available for models with poroportional fan pressure regulation. It moves the condensing pressure set point in order to lower the fan speed and thus reduce noise (specifically at night). If low noise is active during cooling, the condenser control set points are increased by 5º bar. If low noise is active in heating, the set points are reduced by 1º...

    ADVANCED FUNCTIONS 11.- FREE COOLING This option takes advantage of external conditions for cooling mode. Freecooling is enabled when outdoor temperature is 1ºC lower than indoor temperature; when the former is: - < 10ºC, the compressors are deactivated and the air intake gate fully opened in order to refresh with outdoor air only (sufficient under these conditions).
