VECTIOS™ PJ Compact air-air rooftop units Free-cooling + outdoor humidity (Group 20) Terminal + unit communication (Group 21) nRunning the unit in free-cooling mode allows it to make best nBy default, the electronic control Vectic is supplied with a use of outdoor air conditions when these are more favourable graphic terminal installed in the electrical cabinet of the unit, than the return air conditions. This allows the cooling capacity but these other configurations also are available: to be reduced. The percentage of outdoor air can vary between 0% and 100%. There are three options for free-cooling management: •Thermal, by comparing the temperatures. •Enthalpic, by comparing the enthalpies. Recommended in cases where a high moisture content in the air is foreseen. • Thermoenthalpic, by comparing the enthalpies and correcting for temperature. This is the optimum solution VecticGD graphic terminal TCO user terminal as it takes the variability of the climate into account. •TCO user terminal installed in the electrical cabinet, instead of the VecticGD graphic terminal. Thermal free-cooling •VecticGD graphic terminal installed in the electrical cabinet and TCO user terminal remote up to 100 meters. •TCO user terminal installed in the electrical cabinet and VecticGD graphic terminal remote up to 200 meters (two TCONN bypass cards must be used from 50 to 200 meters). •VecticGD terminal installed in the electrical cabinet and VecticGD terminal remote up to 200 meters (two TCONN bypass cards must be used from 50 to 200 meters). 200 m Dry temperature Enthalpic free-cooling RJ12 TCONN TCONN 0,8 m Terminal VecticGD Vectic Dry temperature •Control without terminal (for units with shared terminal in a pLAN network). nBy default, the electronic control is configured for a stand- alone unit, but it is also possible to place it in a pLAN network (µPC MEDIUM Local Area Network) as Master or Slave. Thermoenthalpic nThis control allows the connection to a centralised technical free-cooling management system by using a specific BMS card for some of the following communication protocols: •RS485 serial cards for network communication with protocols: Carel, Modbus, LonWorks®, BACnetTM MSTP, Konnex. •Ethernet pCO Web card for network communication with protocols: Modbus TCP/IP, BACnetTMEthernet, TCP/IP, SNMP V1-2-3, FTP and HTTP. Dry temperature nOutdoor air humidity sensor (compulsory in units with optional enthalpic or thermoenthalpic free-cooling). There are 2 options: •Sensor supplied with the unit. •Sensor installed on another unit of the local network (pLAN).
