Outdoor unit for the production of chilled water with hermetic rotary Scroll compressors, ozone-friendly refrigerant R410A, axial-flow fans, shell and tubes exchanger and electronic expansion valve. The range is composed by units equipped with four, six and eight compressors in multi-circuit configuration.
The controller W3000SE Compact is characterized by proprietary advanced functions and settings. The keyboard commands and a fully functional LCD display, which allows for consultation and intervention unit by means of a multi-layer menu with a choice of the language setting. The temperature control algorithm is based on the exclusive QuickMind with self-adaptive logic, useful in systems with reduced water content. Alternatively, controls may be set proportional or proportional-integral. The diagnostic includes a comprehensive alarm management, with the black box functions (PC) and alarm (via display or PC) for a better analysis of the unit. For systems consisting of multiple units you can control the resource owners through optional devices. It can also be implemented in the accounts of consumption and performance. Supervision is provided via several options, with proprietary devices or integrated into third party systems using the ModBus, Bacnet, Bacnet-over-IP, Echelon LonWorks. Compatibility with remote keyboard (management up to 10 units). The presence of programmable timer allows the creation of a profile containing the operation up to 4 days and 10 bands. To defrost logic is employed owner of an auto-adaptive, characterized by monitoring multiple operating parameters and environmental conditions. This reduces the number and duration of the defrost for the benefit of the overall energy efficiency.
