Features
LOW GWP REFRIGERANT
The new generation refrigerant R454B is the most eco-sustainable alternative to traditional refrigerant R410A, offering a 76% reduction in terms of GWP (Global Warming Potential GWP of R454B = 467, GWP of R410A = 1924 as per IPCC rev. 5th) and zero impact on the ozone layer.
WIDE OPERATING LIMITS
These units are operative at full load in heat pump mode down to -15°C outdoor air temperature, and up to 46°C in chiller mode without needing additional options. At -15°C outdoor air temperature, these heat pumps are able to produce hot water up to 42°C at full load.
TWO SOUND EMISSION LEVELS
Two different sound emission levels available. This means the best unit can be identified based on requirements, according to the system where it will be installed and the application.
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.

Electronic control W3000TE
The W3000TE controller offers advanced functions and algorithms.
The Compact keypad features an easy-to-use interface and a complete LCD display that allows consulting and intervening on the unit by means of a multi-language menu (19 languages are available).
The regulation is based on the patented “Quickmind” water temperature regulation logic uses self-adapting control to maintain flow temperatures and optimise performance even in low water content scenarios. As an alternative, the proportional or proportional-integral regulations are also available.
The diagnostics comprises a complete alarm management system, with the “black-box” (via PC) and the alarm history display (via display or also PC) for enhanced analysis of the unit operation
Optional proprietary devices can perform the adjustment of the resources in systems made of several units. Consumption metering and performance measurement are possible as well.
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 the remote keyboard (up to 8 units).
The defrosting (air source reversible unit only) follows a proprietary self-adaptive logic, which features the monitoring of several operational parameters. This allows to reduce the number and duration of the defrost cycles, with a benefit for the overall energy efficiency.
