VECTIOSPOWER TM PJ Compact air-air rooftop units Factory options and accessories (..continuation). The “Selection Software” includes the option as mandatory In following picture, electronic PCB and 4 zone terminals when return temperature is lower than 20ºC (with 15ºC as are detailed. Connections can be found in the Vectic control the minimum allowed value). manual. Electrical cabinet nZoning of the air flow up to 4 different zones. This option allows the management of the air flow of the zone 1 unit to condition up to 4 different zones with a minimum air (addr.11) Servo. zone 1 flow of 35% (all of them in same operating mode: heating or cooling). This function allows to adapt the indoor air flow to the installation requirements. zone 2 (addr.12) Servo. zone 2 zone 3 (addr.13) Servo. zone 3 zone 4 (addr.14) Servo. zone 4 Note: In case the unit includes enthalpy or thermoentalpic free cooling (T+H control) an extra return T+H sensor in the offer is required. If the unitadditionally includes CO2 probe, it must be a return probe and not an ambient probe. Sensors (Group 19) nSensor(s) of ambient temperature. There are 3 options: • One NTC sensor connected to the control board. Note: An ambient sensor with RS485 communication is required for installation at more than 30 meters. • One to four sensors with RS485 communication. •Sensor(s) installed on the master unit of the local network (pLAN). nOne to four sensors of ambient temperature + humidity, Regulation gives the control signal to the dampers installed with RS485 communication or installed on the pLAN in each zone (dampers and servomotors for those dampers network. This sensor is compulsory in units with enthalpic not supplied). The unit modifies the air flow and capacity or thermoenthalpic free-cooling (optional). In this case, the depending on information coming from sensors in each zone outdoor air humidity sensor is also added. and considering active zones in each moment. The option includes 4 zone terminals (one for each zone) and a control board supplied in an independent box. The 4 terminals, the PJ unit main board and also the servomotors that control dampers in each zone are connected on this T or T+RH T or T+RH T or T+RH T or T+RH sensor sensor sensor sensor board (dampers and servos not supplied). The temperature information for each zone is coming from No.1 No.2 No.3 No.4 Vectic temperature sensor integrated inside each zone terminal. It 24 Vac is not needed to install any extra ambient sensor. GND 260 260 CATALOGUE 2021 :021:021
