When remote controllers are used, each master unit must have the capability to control up to 7 slave units if required (all will operate to the same conditions as the master unit). Cylon (or other Modbus compatible) BMS Interface RBC-LG1/LTX-51 TCB-PCNT20E This combination of a Lon Works interface and RealTime Controls LTX-51 shall allow the Toshiba air conditioning systems to communicate with a Cylon BMS. An RBC-LG1/LTX-51 combination shall be hard wired to each indoor unit via the XY terminals on each protocol converter (TCB-PCNT20E), to enable the user to individually control up to 16 master indoor units when connected to a single system. Each master indoor unit is to be fitted with a protocol converter. Multiple interfaces may be connected to a Cylon network to enable the user to monitor and adjust indoor units alongside any other integrated building services from a single PC. The LTX-51 connects directly to the modbus port on a UCC4 to permit all functions and settings to be modified. All of the system fault codes can be passed back through to the BMS that will allow the faults to be managed by the BMS alarm supervisor. The interface shall permit the user to access the control of the system remotely via the use of a modem connection. In addition the interface shall facilitate the use of Remote Controllers (RBC-AMT32E, RBC-AMS41E, RBC-AMS51E-ES or RBC-AS41E) to provide the user with local control of the air-conditioned space. When remote controllers are used, each master unit must have the capability to control up to 7 slave units if required (all will operate to the same conditions as the master unit). Windows Package & Windows Gateway RBC-WP1-PE TCB-IFLN642TLE TCB-PCNT20E A Windows Package (RBC-WP1-PE) shall be used in conjunction with a Gateway (TCB- IFLN642TLE). Each Gateway shall have the capability of individually controlling up to 64 master indoor units. Up to 16 Gateways can be connected to each Windows package. Each Windows Gateway is then linked to the PC via the AB terminals. If Digital / Super Digital Inverter units are to be added a Network Adaptor (TCB-PCNT30TLE) is required for each master indoor unit with the exception of the High Wall models. The Windows Package shall enable the user to control up to 1024 individual indoor units, and via the Gateway be capable of adjusting, managing and displaying all the following control functions: Mode of Operation (Auto, Cool, Heat, Fan Only)

17 Temperature Set Point (18 C to 29 C) Fan Speed (High, Medium, Low & Auto) Louvre Position (Where applicable) On/Off Fault Code Diagnostics Sensor Data Indoor Unit Locked Off On/Off Control Only Multiple Time Scheduling In addition local control may be provided to any or all zones by the use of Remote Controllers (RBC-AMT32E, RBC-AMS41E, RBC-AMS51E-ES or RBC-AS41E). When remote controllers are used, each master unit must have the capability to control up to 7 slave units if required (all will operate to the same conditions as the master unit). The controls software shall also enable the user to display unit locations via site specific floor plans and transmit system alarms via the following media types: - Fax, SMS, Modems, and Pager. To enable the Windows Package to be installed the following minimum system requirements shall be provided either by the end-user or the installer: - PIV or Greater Processor 512MB RAM Hard Drive with 50MB Free Space 16bit High Colour 800 x 600 SVGA or Greater Display (Not shared graphics card) Win NT, Version 4.0 or Later (Service Pack 3.0 or Greater) Win 2K Win XP (Not Suitable for Windows Vista) Internet Kit RBC-IK1-PE An Internet kit shall be used in conjunction with the Windows Package and Lonworks Interface(s) to provide the following capabilities: Remote computer access to the server where the Windows Package is installed to allow up to 5 users at any one time to view, or change data using Microsoft Internet Explorer. Two levels of control: o Monitoring o Full Control Immediate access to operating conditions and historical performance, facilitating rapid response to customer/user enquiries.
