ERACS2-WQ 0802 - 1502
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.
HOT WATER SUPPLY
Supply of hot water in use up to 60°C, offering maximum versatility with respect to different plant engineering solutions.
INTEGRATED CONDENSATION CONTROL
A 2-way valve is supplied as standard for the condensing pressure control. For all the applications in which a constant water flow through the condenser is needed, a 3-way valve option is also available by request.
Produkt-Informationen
Produkt-Informationen- - - Standard efficiency
- Integral acoustical enclosure (base or plus)
- Several devices for condensation control.
- Electronic expansion valve
- Set-up for remote connectivity with ModBus/Echelon protocol cards
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.
