Features

REFRIGERANT GAS R410A

The use of R410A achieves better energy efficiencies while respecting the environment (ODP = 0)

INTEGRATED HYDRONIC GROUP

The optional built-in hydronic module already contains the main water circuit components; available with single or twin in-line, for achieving both low or high head.

W3000SE Compact

W3000SE Compact offers advanced functions and algorithms. The keypad features an easy-to-use interface and a LCD display, allowing you to consult and intervene on the unit by means of a multi-level menu, with selectable language setting. Regulation based on the exclusive QuickMind algorithm, including self-adaptive control logics, beneficial in low water content systems. As alternatives the proportional- or proportional-integral regulations are also available. The diagnostics includes a complete alarm management, with the "black-box" and alarm logging functions for enhanced analysis of unit operation. For multiple unit 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. - Internal real time clock available 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 reduces the number and duration of the defrost cycles, with a benefit for the overall energy efficiency.
