The BMS Gateway accessory allows direct communication from a heat pump to building management systems. It allows commands and data to be transferred in both directions.

The gateway is installed inside the heat pump or master control panel’s electrical enclosure on a factory
supplied DIN rail. Then, it is wired to the BMS system through ethernet and/or control wiring terminals. On C-Series heat pumps, a Communication Module addon is also installed on the PLC controller and wired to the gateway.

One gateway accessory package is required for each stand alone heat pump that is to be connected to a
BMS system. Systems with Master Control Panels do not need this accessory if the BMS option was selected for the MCP.
