CRS-Gateway

This connected roof gateway, model CRS-Gateway, is part of the Watts Connected Roof System. The gateway unit receives water level and temperature data from monitor units on a 915MHZ wireless connection and compares the water level between the drains on the roof. If the level becomes critical at one of the drains, this data is relayed from the monitor and a warning is issued by the gateway. The display on the gateway can be visually checked for warnings or the gateway can send warnings and other pertinent data via its RS-485 port (MODBUS protocol) to a building management system (BMS) for a full overview of the entire installation. The gateway comes with a relay that can trigger an audible alarm as a warning and/or it can be configured to control (on/off) a snow melting system.
