 "summary": "Valent's ERV controller offers BACnet MS/TP, BACnet IP, Modbus RTU and Modbus TCP. The BMS can enable the unit, reset alarms, write temperature, static pressure, CO2 and VOC setpoints, command supply and exhaust fan speed, enable the economizer, and send outside temperature, RH, CO2, static and VOC values from the BMS behind source-select points and a watchdog. Read-only objects cover sensors, ramps, the unit status mode, the latest alarm, fan status inputs and individual alarm flags.",
