CARRIERrtc electronic control ( optional )
Electronic module with microprocessor comprised of a control board and a pGD1 graphic terminal installed over the unit electric panel and accessed using a polycarbonate collapsible window .
Optionally this terminal can be replaced by a TCO user terminal for installation inside of the premises . In this case the TCO terminal are not allowed to access parameters control and time schedule .
The management of the ambient temperature is controlled via a NTC ambient probe . This probe can be replaced by 1 or 2 RS485 probes .
In addition to the functions described in CARRIERrtc basic & medium control , this control allows controlling optional elements such as :
-- Cooling recovery circuit .
-- Electronic plug-fans .
-- Enthalpic or thermoenthalpic free-cooling .
-- Smoke detecting station .
--
Air quality probe for measuring CO2 and / or volatile compounds ..
-- Energy meter .
--
Refrigerant leak detector .
It also manages a local connection between units through a pLAN network (µ PC MEDIUM Local Area Network ), thus allowing communication of data and information for a maximum of 15 units . This enables the reduction of the number of pGD1 terminals , since a single shared terminal can monitor all control boards . It also allows to share the reading of some probes .
