SPLIT-SYSTEM UNITS 38NZ/NF & 40NZ/NF
CARRIERrtc basic & medium electronic control (standard)
Available in two versions:
models 90 to 182 models 200 to 360
CARRIERrtc basic : CARRIERrtc medium :
The following features improve the energy management of the installation: Defrosting management (in heat pump units). Possibility of intelligent defrosting that reduces energy consumption of the heat pump, by adjusting the time between defrosting operations to the actual needs of the unit. Compensation of the setpoint based on the outdoor temperature. This function prevents thermal “shock” between the inside and outside of the premises whilst at the same time provides signiﬁcant energy savings Time schedule that reduces energy consumption, adjusting the needs of air conditioning of the building throughout the day. TCO terminal has a schedule programmer with an intuitive graphic interface that allows 6 time slots to be chosen for each day of the week. A change in the setpoint temperature or the disconnection of the unit can be scheduled in these time slots (according to the building occupancy).
Note: Optionally, the models 90 to 182 can incorporate the CARRIERrtc medium version. CARRIERrtc basic & medium control is an electronic module with microprocessor comprised of a control board and a TCO user terminal that ensures the following functions: - Selection of the operating mode: • • • • • HEATING COOLING AUTO DEHUMIDIFICATION FAN (no icon).
Modiﬁcation of the setpoint. Permanent control of the operating parameters. View of the values measured by the sensors. View of the alarms produced by means of codes. Timing of the compressors. Control of the compressor discharge temperature by probe. - Control of the ambient temperature thanks to the probe incorporated into TCO terminal. This probe can be replaced by an return or ambient probe that would be installed in the control board. - Control of the outlet temperature to improve thermal comfort level of the installation. In cooling mode this control prevents excessively signiﬁcant drops in the ambient temperature. In heating mode, it prevent the stratiﬁcation of the hot air masses.
Optional functions: - Control of the auxiliary electrical heaters. - Proportional control of a hot water auxiliary coil. - Humidity control. - Anti-ﬁre safety. - Operation during all seasons via the condensation and evaporation pressure control. - Detection of clogged ﬁlters and air ﬂow control. - Connection to a centralised technical management system (BMS) for supervision (please see “Optional” chapter). Optionally, this control can have a terminal for pGD1 maintenance that facilitates the initial scheduling of the unit, the modiﬁcation of the operating parameters and the description of the alarms produced.
