VECTIOSPOWER TM PJ Compact air-air rooftop units Factory options and accessories (..continuation). There are three options for free-cooling management: The specific functionality will be configured on site (according Thermal, by comparing the temperatures. to the Vectic regulation manual). • •Enthalpic, by comparing the enthalpies. Recommended in cases where a high moisture content in the air is foreseen. • Thermoenthalpic, b comparing the enthalpies andy correcting for temperature. This is the optimum solution Vectic 1 Vectic 2 Vectic 15 as it takes the variability of the climate into account. Master unit, address 1Slave unit, address 2 Slave unit, address 15 One function that helps improve energy management is nocturnal free-cooling. This feature allows the compressors to be disabled in summer with programming, the unit works VecticGD terminal VecticGD terminal VecticGD terminal providing free-cooling at night, when the outdoor conditions (shared) (private) (private) are favorable. This allows the cooling demand to decrease The pLAN network allows to have the following functionalities significantly early in the day. depending on the parametrized configuration: nOutdoor air humidity sensor (compulsory in units with • Master/Slave: optional enthalpic or thermoenthalpic free-cooling).
