It is designed to operate in a stand-alone configuration or, with the support of a communications network, as an integral part of a comprehensive building automation system. Also the MR-HP controller provides sufficient applications flexibility to address multiple heat pump (HP) configurations. It is designed to operate in a stand-alone configuration or, with the support of a communications network, as an integral part of a comprehensive building automation system. Plug-on terminals for a thermostat, communications, power, and four external inputs. Plug-on terminals for six external outputs. A 12-position DIP switch for setting up initial application/ equipment configurations. Indicator lamps for output status, communications, power, and self-test.
