ANTIFREEZE MIXTURES EVAPORATOR HYDRAULIC CIRCUIT Machines can work with antifreeze mixtures although not necessary, because the machines do not accept outlet temperature of the liquid cooled below 4 C, the use of glycol mixture is a generic antifreeze protection, for machines not in operation during the winter season. CONDENSER HYDRAULIC CIRCUIT In case of heat exhaustion through a close hydraulic circuit on a dry cooler, is mandatory to load the circuit with antifreeze mixture. The choice of glycol percentage may be based on the following table: Freezing point [ C] % Ethylene glycol volume % Propylene glycol volume -10 24 27-20 36 39-30 46 49 STORING TEMPERATURE If the machine is not installed on receipt and is stored for a long time, store it in a protected place, at temperatures ranging between -30 C and 50 C in absence of superficial condensation and direct sun light. 5

MICROPROCESSOR CONTROL SYSTEM The microprocessor controls the machine guaranteeing on the one hand a precise and punctual temperature regulation, on the other hand integrating the safety functions relative to all fluid-dynamic circuits.the microprocessor controls the outlet temperatures of the chilled water through two set parameters, xk1 e xk2, as outlet temperatures from the evaporators, with possible remote commutation through voltage free contact. In any case, the microprocessor will modulate the electric input to the compressors motors to guarantee the maximum temperature precision in respect of the working range allowed by the centrifugal compressors. For multi-compressor units, for any working condition, the control will cleverly manage the number of compressors to be activated in a combined optics of safety and energy saving. The system includes: Compact controller for DIN rail mounting 24Vac 50/60Hz. 16-bit microprocessor. 2 +2 MB flash memory (retains data without power) and memory RAM 512kB.

OPTIONAL ACCESSORIES RILHEVA - PLANT MONITORING AND MANAGEMENT GPRS SOLUTION. Rilheva is a part of the RC Group Artificial Intelligence. Is the most advanced solution in unattended monitoring and remote management for an air conditioning plant. Rilheva can be used everywhere in the World, through an easy web access from mobile devices such as PC s, tablets or smartphones. The solution is available for PC, tablet and smartphone: Thanks to an easy access to rcgroup.rilheva.it website the user is provided with an interface that allows him to operate directly on the field. Dedicated apps for Android and ios operative systems are available for the mobile network access. Each device can manage up to 400 Modbus registers and up to 31 (linked in serial) RC Group units: Air conditioners; Liquid chillers; Heat pumps and multifunction units. MAIN FEATURES: Real time plant s check; Units remote control (start/stop, set point modification, alarms reset); Customizable visualization and analysis (historical) of each unit data; Charts creation and export; Data monitoring on maps; SMS, Mail, Speech Synthesis, FAX and APP (ios e Android) notifications; Integration of different devices in the system (pumps, cameras, etc.) through RS485 communication ports on ModBus RTU communication protocol. MAIN COMPONENTS: The system is factory assembled and it includes: RILHEVA electronic card that measures physical data (pressure, levels, temperatures, failures, unit conditions, ) through RS485 communication ports on ModBus RTU communication protocol and transmits them with a GPRS modem to a central server where they are stored, elaborated and made available to enabled users through the use of a common internet browser. Omni-directional dual band (900 and 1800MHz) antenna with magnetic base for data transmissions and receptions. Modular transformer TMC 15/12 230V / 4-8-12 V AC 15 VA for the power supply. IMPORTANT The optional accessory requires the installation of the serial port RCcom MBUS/JBUS on each unit to control (optional accessory, not included). The optional accessory requires also the installation of a SIM card with an internet data subscription with a mobile phone provider (not included) and an annual subscription to RC GROUP service. ADDITIONAL MODULE FOR plan CONNECTION When the RS 485 serial connection is not available in the units to control is possible to connect Rilheva to a plan network. This option requires an additional module installation. The additional module is electrically supplied by the same modular transformer used for RILHEVA. The additional module is linked to RILHEVA by the RS232 communication port. RC GROUP SERVICE SUBSCRIPTION Several annual subscription forms are available. Please contact RC Group for further information. RILHEVA ELECTRONIC CARD WARNING For further information please consult the Rilheva TECHNICAL CATALOGUE. 16

MASTER PLANT SEQUENCER Master Plant SEQuencer is part of the RC Group Artificial Intelligence. Master Plant SEQuencer offers some useful tools for the management of several units installed in parallel on a hydronic network: liquid chillers; heat pumps, multifunction units and dry coolers. HIGHLIGHTS The choice of RC Group reliable, made with hi-tech components, with extremely high energy efficiency units is only the first step. Only with proper plant measurements, analysis and control instruments is possible to grant a long-lasting efficiency and quality. The features of Master Plant SEQuencer add value to the installed units, to the plant and to the building. ENERGY SAVINGS MAXIMIZATION Master Plant SEQuencer maximizes energy savings by the activation of the RC Group units that offer the highest possible efficiency according to the required working conditions. Master Plant SEQuencer: Is directly connected with the RC Group units using MP COM microprocessor by a serial link; Automatically recognizes the type of RC Group chiller and acquires the key information by a plug and play logic (SEQuencer has in its memory the mapping of the RC Group chillers); Always activates the chiller offering the highest possible efficiency according to the required working conditions optimizing the plant s energy efficiency. Cuts energy bills significantly. NOISE REDUCTION Master Plant SEQuencer follows all the law requirements against noise, installation in the historic city centres and noise limitation during night hours.
