Systemair RC-C3DOC - Room Controller with Modbus communication

Room controller based on multiple physical values and control states in different configurable operation modes and sequences Functions: • Heating control, separate controls of the heating valve and VAV in heating mode • Cooling control, separate controls of the cooling valve and VAV in cooling mode • CO2 (or other values) control by VAV • Dew point surveillance, protection • Frost protection • Different operation modes switched according to room occupation state • Energy conservation procedures in case of room control conditions disturbance (e.g. open window) The following measurement and detection capabilities are included or can be connected to the RC: • Room temperature measurement on board • External temperature measurement connectable via analog input • External CO2 (or other value) measurement connectable via analog input • External change-over switch connectable via digital input • External dew point detection connectable via digital input • External presence/occupation detection connectable via dig...
