Unit description
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 can 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. Each circuit works with a semi-hermetic screw compressor using R134a, two shell and tubes heat exchangers shared by both circuits, a cold heat exchanger on plant’s side that acts as an evaporator in the production of cold water, a heat exchanger on plant’s side that works as a condenser in the production of hot water, and a source side coil heat exchanger that works as either condenser or evaporator as required by the loads.

Features
UNIQUE PROPOSAL Unit designed to satisfy the hot and cold side requirements simultaneously, for 4-pipe systems without any particular operation mode setting.
ENERGY SAVINGS Energy savings guaranteed by advanced operation logic. The best operation mode is set completely automatically and independently by the unit’s controller, in order to minimize the absorbed energy whatever the heating and/or cooling demand might be.
WIDE OPERATING RANGE Unit´s operation guaranteed with external air temperature down to -10 °C during winter and up to 46 °C during summer.
VERSION ´XL-CA-E´ AVAILABLE Exclusive Premium version. Together for the first time, the lowest noise level on the market combined with the maximum efficiency in any operating mode.
HOT WATER SUPPLY Supply of hot water in use up to 60°C, offering maximum versatility with respect to different plant engineering solutions.
Accessories
Hydronic group
VPF (Variable Primary Flow) kit: variable flow pumps with on board regulation
Electronic expansion valve
Set-up for remote connectivity with ModBus/Echelon protocol cards
Controls
Controls
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.
