FOCS-WNR 0802 – 3202

Reversible unit, NRG line, total heat recovery, water source
Cooling capacity 183 – 839 kW

NECS 0202T - 0612T
Heat pump unit for indoor installation, designed for 2-pipes plants application for summer/winter air conditioning. Unit complete with a section for the condensation heat reclaim: a dedicated heat exchanger produces on request hot water for secondary uses (domestic hot water, air treatment in AHU, …). Semi-hermetic screw compressor, R134a, shell and tube heat exchangers both, plant-side (primary, working as an evaporator or condenser as a function of unit´s commutation, and secondary, working only as a condenser) and source-side. Frame in polyester-painted galvanized steel.

Features

  • UNIQUE PROPOSAL
    Unique proposal: unit designed to satisfy, according to the mode of operation, requirements of cold water, hot water for heating or hot water for domestic use
  • ENERGY SAVING
    Free domestic hot water during summer season.
  • HOT WATER SUPPLY
    Hot water supply up to 55 °C. In winter mode the unit manages hot water production in the plant-side heat exchanger and in the reclaim one, with priority setted by customer, eventually at two different set-points
  • INTEGRATED CONDENSATION´S CONTROL
    A 2 way valve is supplied as standard for the condensing pressure control. For all the applications in which a constant waterflow through the condenser is needed, a 3-way valve option is also available under request.

Accessory

  • Integral acoustical enclosure (type base or plus)
  • Several devices for condensation´s control
  • Electronic expansion valve
  • Set-up for remote connectivity with ModBus/Echelon protocol cards

Controls

  • W3000SE Large
    The W3000SE Large controller offers advanced functions and algorithms. The keypad features an easy-to-use interface and a complete LCD display, allowing to consult and intervene on the unit by means of a multi-level menu, with selectable language setting. The regulation operates on both water circuits featuring the step-wise regulation referred to the return water temperature with proportional logic. This allows to satisfy simultaneously the different requests of both cooling and heating, according to the selected operation mode. The diagnostics includes a complete alarm management, with the “black-box” and alarm logging functions for enhanced analysis of the unit operation. For multiple units’ systems, the regulation of the resources, via optional proprietary devices, can be implemented. Energy metering, for both consumption and capacity, can also be developed. 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, Echelon LonWorks. Compatibility with the remote keyboard managing up to 10 units. Availability of an internal real time clock for operation scheduling (4-day profiles with 10 hour belts). The defrost adopts a proprietary self-adaptive logic, which features the monitoring of numerous operational parameters. This allows to reduce the number and duration of the defrost cycles, with a benefit for the overall energy efficiency.
