1 INTRODUCTION This software personalised for Rhoss S.p.A. will proceed at the control and regulation of single/twin/fourth-compressor chiller units, single/twin-circuit; with the possibility to work in chiller modality or heat pump, by a pCOEM for the management of Rhoss personalised double-circuit. The software will include the following characteristics: • Chiller + heat pump • Air/water • Single/twin/fourth-compressor • Single/twin-circuit • Pump/s control of main circulation • Pressure condensation control of 1 or 2 fan rows • Management of the contemporary and separated defrost in temperature/pressure • System and circuit alarm • Alarm log • Communication to the serial supervisor system We provide the use of a PGDO remote keyboard, with a Rhoss personalised keyboard.
