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 (μPC 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.

Optional for the outdoor unit 38NZ/NF
Outdoor environment Temperature - Operation during all seasons via the condensation pressure control by damper (up to -15ºC). Safety Soft starter of the supply fan which prolongs the set time mainly aimed at installations with cloth ducts.
Protection grille for the coil
Installation - Antivibration mounts made of rubber. - Service valves for cooling connections. - Oil separator for cooling connections with maximum equivalent length of the cooling line greater than 50 metres. - Position of air supply of the outdoor unit: side or upper. - Different conﬁgurations of available pressure from 7 to 35 mm.w.c - Air coil protection grille (it’s not compatible with the air ﬁlter). - Gravimetric ﬁlters in the return air. The ﬁlters frame is removable, and upon request, it is possible to supply the frame separately with the unit 38NZ/NF, to be joined on site (width = 53 mm) Acoustic - Acoustic insulating cover for compressor Electric panel Electrical power supply with neutral. Energy meter for monitoring of the power consumption of the installation (with CARRIERrtc control). Available if the unit does not incorporate electrical heaters.
