1 Energy Flex Electronic controllers for centralised air-conditioning units General Description Eliwell, a leading manufacturer for over a decade of control equipment for small and medium-size air conditioning units is proud to present Energy Flex, the new range of compact devices with advanced functions and innovative applications for the HVAC market. Features: Energy saving and innovative applications in a new range of controllers for the HVAC market Single or double-circuit control of centralised air-conditioning systems with 2 or 4 compressors (steps), such as: Chiller : air-air; air-water; water-water; Condensing units: Air Chiller; Water Chiller; Heat Pump: air-air; air-water; water-water with gas inversion; water-water with water inversion; Air Heat Pump Water Heat Pump Main functions: User interface with configurable buttons Navigation Menu configurable Parameters set through device interface / remote terminal or PC Large Historical alarms memory Copy Card to upload and download the controller parameter map Remote terminal (up to 100 m) to be directly connected without serial interfaces Configurable inputs NTC, 4 20mA, 0...1V, 0...5V o V by parameters Thermoregulation on inlet or outlet water temperature configurable Automatic changeover Dynamic set point ON/OFF and proportional condensation control without external devices up to 2A Boiler control or electric heater for the heating Indoor ventilation control Management of semi-hermetic, scroll and screw compressors up to 2 stages Control of single refrigerant circuit up to 4 compressors or 1 compressor with 4 stages Control of 2 refrigerant circuits up to 2 compressors/stages per circuit Summary Models and Technical data Energy SB600 SB646/C/S 4 DO 6 SB655/C/S 5 DO 5 Energy SD600 6/C/S SD636/C/S 3/4 DO 6 SD655/C/S 5 DO 5 Energy SC600 SC646/C/S SC636/C/S 3/4 DO 6 SC655/C/S 5 DO 5 Expansions SE632 - SE646 - SE655 4/5 DO 6/5 Remote terminals SKP10 32x74mm remote terminal SKP22(L) - SKW22(2L) LCD remote terminal Accessories AIR CONDITIONING LEGENDA DO Digital Outputs Analogue Outputs

2 Plus points Versatile installation Thanks to the offer of several models and highly flexible configuration, the controller can be adapted to suit a variety of applications, from the single unit to the whole system. The hardware platforms have several I/O configurations and several sizes to give maximum versatility of installation. The expansion modules enable to increase the number of resources to control, so to meet even the most complex application needs User interface Connectivity and control The whole Energy Flex range has front plates that can be customised with icons and manufacturer s logo for a market differentiation. The 4-digit display with 18 icons, 7 of which configurable, offers a clear readability, with dedicated units of measures for each value displayed. Using the 4 push buttons it is possible to activate all the main controller functions, like modifying the current display, selecting the operating mode, activating defrost and switching the controller on/off, as well as browse the menu organized into folders. The access to the folders and parameters is configurable through three different levels: end user, service and constructor. The Energy Flex range is completed by different remote terminals: with a small-dimension led display for panel mounting (SKP10) and the others with a backlit LCD display (SKP22L, SKW22L), with modern and attractive design that easily fits in with the furnishing, for wall mounting. All Energy Flex controllers are equipped with a serial connection which enables the easy integration with the plant supervision, monitoring and management systems. The management of most of the systems functions is possible through the ModBus standard communication protocol, ensuring a complete control of the plant. Thanks to the connectivity moduls RadioAdapter, LanAdapter or BusAdapeter, it is possible to exploit the connections Wireless or the Ethernet or even RS 485 for the remote plant management. The new SW DeviceManager, is not used to monitor and record the system variables in real time, simplifying the plant set-up for the lab tests, but enables also a quick controller programming. With an optional Copy Card it is possible to upload and download the controller parameter map for fast configuration, download the alarm history and upload the software applications. Energy saving High capacity within the microprocessor's memory equips the instrument with advanced adjustment algorithms. This includes a modulating control of the water pump, dynamic defrost, analogue condensation control and heat pump deactivation for very low external temperatures. These controls can be used to reduce energy consumption within the installed system with significant impact. The addition of a high number of analogue outputs provides increased flexibility so that any kind of utility can be managed with power modulation to increase the energy efficiency of the device.
