Features
REFRIGERANT GAS R410A
The use of R410A achieves better energy efficiencies while respecting the environment (ODP = 0)
ELECTRONIC EXPANSION VALVE SUPPLIED AS STANDARD
The use of the electronic expansion valve generates considerable benefits, especially in cases of variable demand and different external conditions. It was introduced into these units as a result of accurate design choices concerning the cooling circuit and the optimisation of operation in various different working conditions.
EXTENSIVE RANGE OF OPERATION
Production of high temperature hot water up to 65°C for space heating and hot water purposes.
STACKABLE UNITS
The special structure of the units (without on-board pumps) is designed to allow two units to be stacked on top of each other without any additional accessories, reducing the space requirements when needing to expand system capacity. The capacity of two heat pumps with the footprint of a single unit.
INTEGRATED HYDRONIC MODULE
The units can be supplied with a hydronic kit on the user side and a hydronic kit on the source side. These kits include all the water circuit components so as to optimize installation space, times and costs.
In addition, a vast selection of pumps are available, up to 13 different models, for both the user side and the source side, which means the best solution can always be configured in terms of flow-rate, available pressure head and power consumption.
INTEGRATED CONDENSATION CONTROL
The unit's electronics manages the most suitable condensing control for each type of application: two-way modulating valve, inverter control for the pumps.
MODULAR CONFIGURATION
Modular configuration with capacity extension up to 400 kW for medium- and high-capacity installations. Ability to manage different thermal loads according to the requirements of both heating and the domestic hot water systems.

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.
