NRCS-Q-Z 0604 - 1204
Multi-purpose outdoor unit for use in 4-pipe systems for the simultaneous production of hot and chilled water by means of two independent hydronic circuits. These units are able to satisfy the demand for hot and cold water simultaneously through a system that does not require seasonal switching and is therefore a valid alternative to traditional plants with chiller and boiler. This unit is equipped with hermetic rotary Scroll compressors, with R410A, axial fans, braze-welded plate-type exchanger and thermal expansion valve. External panels in Peraluman and base in galvanised sheet steel with paint finish. The range includes two-compressor and four-compressor versions, both with two independent refrigerant circuits.

Features
UNIQUE PROPOSAL
Unit designed to satisfy the hot and cold side requirements simultaneously, for 4-pipe systems without any particular operation mode setting.
CUTTING-EDGE ELECTRONICS
The Energy Raiser units are fitted with an evolved electronic unit that allows fully automatic management of the best type of operation to meet the load requirements
VENTILATION CONTROL FOR LOW-TEMPERATURE OPERATION
The standard units come fitted with pressure-operated control of ventilation, which allows the unit to produce cold water with an external air temperature down to -10°C
INTEGRATED HYDRONIC GROUP
The built-in hydronic module already contains the main water circuit components; it is available with single or twin in-line pump, for achieving both low or high head, available for both plant and recovery circuits (up to 4 pumps).

W3000SE Large
The controller W3000 large offers the latest control and functions specially developed for these units.
The keypad is generously sized with full operating status display. The controls and detailed LCD make access to unit settings easy and safe. These resources allow one to directly intervene on the unit settings through a multilevel menu, available in several languages.
The diagnostics includes full management of alarms with black-box functions and alarm record for better analysis of unit performance.
For multi-unit systems a special device to coordinate and manage all the resources is available as an option; energy metering device. Supervision can be easily developed via proprietary devices or the integration in third party systems by means of the most common protocols as ModBus, Bacnet, Bacnet-over-IP, LonWorks.
Compatibility with remote keyboard (management up to 10 units). Clock available with programming of operation (standard 4 days and 10 time bands).
Temperature regulation managed on the two water circuits, with a proportional logic referred to the return water temperatures. This simultaneously satisfies the different heating and cooling requests, with no need of mode change.
Exclusive self-adaptive defrost logic, monitoring multiple operational and ambient parameters, which reduces the number and duration of the defrost cycles, benefiting the overall energy efficiency.
