Unit description
Multi-purpose indoor unit for use in 4-pipe systems for the simultaneous production of chilled and hot water by means of two independent water circuits. These units are able to satisfy the demand for hot and cold water simultaneously through a system that does not require seasonal switching. Each circuit works with a semi-hermetic screw compressor using R134a, and three tube nest heat exchangers, a cold exchanger on the user side shared by both circuits that acts as an evaporator in the production of cold water, a heat exchanger on the user side that words as a condenser in the production of hot water, and a source side exchanger that works as either condenser or evaporator as required by the loads.
Versions
- - - Basic
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
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.
Accessories
- Integral acoustical enclosure (base or plus)
- Several devices for condensation control.
- Electronic expansion valve
- Set-up for remote connectivity with ModBus/Echelon protocol cards
Controls
Controls
- Electronic control W3000TE
W3000TE controller features a large format keyboard with wide LCD display in order to ensure an easy access to the unit's setup and a complete view of the unit's status. The assessment and intervention on the unit is managed through a multi-level menu, with selectable user’s language. The led icons immediately show the operating status of various components. As alternative, the innovative KIPlink user interface allows one to operate the unit directly from a smartphone or tablet. The regulation operates on both water circuits featuring the step-wise regulation referred to the return water temperature with proportional logic. This simultaneously satisfies the different requests of both heating and cooling, with no need of mode setting. Complete alarm management system is available, with the “black-box” and the alarm history display functions. Optional proprietary devices adjust the resources in multiple-unit systems. Consumption metering and performance measurement are available and 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 programmable timer manages a weekly schedule organised into time bands (up to 10 daily time bands associated with different operating set points) to optimise unit performance by minimising power consumption during periods of inactivity. Proprietary self-adaptive logic for the defrosting features the monitoring of several operational parameters. This reduces the number and duration of the defrost cycles, benefiting the overall energy efficiency.
