Istruzioni per l'uso CARRIER 30RH017

[. . . ] An auto-adaptive control system ensures intelligent control of the compressor start-up sequence. Features n Refrigerant R-407C is a blend of R-32, R-125 and R-134a, n Prepainted steel panels. [. . . ] The advanced concept of the scroll allows reverse rotation due to incorrect wiring, without impairing the operation of the compressor. These compressors are especially designed for operation with R-407C. n The hydronic module is factory-installed. This eliminates the need to install the necessary components on site, making the unit more compact and easy to install. 1 Water fill system: - Spherical check valve - Pressure reduction valve - Safety valve Hydronic kit - Flow switch - Suction pressure gauge - Expansion tank - Spherical shutoff valve - Filter - Pressure pump - Spherical control valve - Discharge pressure gauge - Automatic purge. PRO-DIALOG Plus control PRO-DIALOG Plus is an advanced numeric control system that combines complex intelligence with great operating simplicity. PRO-DIALOG Plus constantly monitors all machine parameters and safety devices, and precisely manages the operation of compressor and fans for optimum energy efficiency. It also controls the operation of the water pump. A powerful control system n The PID control algorithm with permanent compensation for the difference between entering and leaving water temperature anticipates load variations, and ensures intelligent leaving water temperature control. n Reset of the leaving water temperature set point (according to the outdoor air temperature or the return water temperature). n PRO-DIALOG Plus control is auto-adaptive for improved heat pump protection. Compressor cycling is automatically adapted to the characteristics of the application according to the inertia of the water loop and prevents dangerous compressor short cycling. Clear and easy-to-use control system n The operator interface is clear and user-friendly: LEDs and numeric displays ensure immediate verification of the unit operating data. n A simple push of the button positioned on the synoptic heat pump diagram gives you immediate display of the usual parameters: temperatures, pressures, set point, compressor run times etc. [. . . ] kW Comp kW Unit kW Cond l/s Pres kPa - Leaving water temperature - Integrated heating capacity - Net nominal heating capacity (instantaneous capacity = gross heating capacity minus the capacity corresponding to the available pressure (flow x pressure/0. 3). - Compressor power input - Unit power input, (compressors, fans, control circuit and pumps) minus the capacity corresponding to the available pressure (flow x pressure/0. 3).
