111.6 The interfacesDepending on the type of controller, a number of interfaces are available:Fig. 1.9: The interfacesUSBEach controller is equipped with an USB interface. The USB interface can be used to:x Make adjustments.x Create a backup of the configuration.x Upload backups or new firmware.The only equipment neccessary is a normal USB-to-Micro-USB interface cable andthe necessary COM-port driver as required by the computer’s operating system.External display (RS-485)This interface enables connecting a remote control unit (e.g. an external touch panel).Communication with the heat pump (RS-485)This interface is used to communicate with the heat pump. To connect the heat pump,a PAW-HPMINT-X model adapter cable is needed. The “X” stands here for either “–U” (a 3 m adapter cable to communicate with the internal unit of a split-heat pump) or“–M” (a 30 m adapter cable to communicate with a MONO-block-heat pump). In thiscase, the HPM functions as a substitute for the operating unit of the heat pump.Network (Ethernet)If the controller is equipped with an Ethernet interface, it can be connected to acommunications network which can in turn be connected to the Internet. The interfacecan be used to:a) Communicate with the controller.b) Connect master and slave controllers when using more than one heat pump in thesystem.RS-485 forexternal displayEthernet for TCP/IP (webserver) and other controllersRS-485 forcommunication withheat pumpUSB to PC(service)
