ELECTRONIC REGULATOR FOR CHILLER CONTROL


The DIN NANO CHILLER electronic module is capable of fully monitoring and controlling air/water and water/water chiller units with up to two compressors, ensuring uniform operation and correctly distributing the working times between the individual machines; all of this with maximum operating safety together with the convenience of being able to install the NANO ECHO Control Console anywhere.

Applications • Air/water and water/water chiller control. Main characteristics • Configurable for control air/water or water/water chillers. • Evaporator flow switch management. • Antifreeze protection management. • Condensing energy saving management based on external environmental conditions. • Configurable stand-by mode. • 0-10 V Analog output for the adjustment of speed of the condenser fans or for modulating control of the evaporator / condenser water pump. • Display of the pressure probe measure in Bar or in °C (conversion based on the type of refrigerant gas selected). • Rotation of compressors according to the time of operation. • Side band regulation. • Configurable digital inputs/outputs. • Night / day management (energy saving). • Clock and calendar. • Password for keys lock. • 3-figure LED display sign, decimal point and plant status icons. • Internal buzzer for acoustic signals. • PEGO programming philosophy guaranteeing immediate start-up. • RS485 serial connection with Modbus-RTU or Telenet protocol. • Power supply 230Vac.
