Cooling system configurations
N O T E
• The following installation examples show typical configurations only for cooling application. In case of heating
installation working also in cooling operation, the responsability of correct system functioning will be of the
installer. The configuration examples given below are only for illustration purposes.
• The split air to water heat pump is pre-configurated to work only in heating mode. In order to allow the only
cooling mode, it is necessary to perform a dip-switch setting and install the drain pan accessory. In the case,
all the heating mode uses for the unit will be prohibited and the LCD user’s interface heating configuration will
disappear.
