THESE PRODUCTS HAVE BEEN SUPERCEDED BY THE FDP3 PRODUCT RANGE
Go to the FDP3 Product Page for further details and datasheets.
The FDP2 range of interfaces provide monitoring and control solutions for Toshiba SMMS, SHRM and Digital Inverter air conditioning systems.
FDP2 interfaces are the basic building block for creating low cost air-conditioning control solutions. A single FDP2 interface can monitor and control up to 8 indoor units as a single group, multiple FDP2s can create more complex groupings. Two versions are currently available, the FD2-F provides basic fault monitoring and control, the FDP2-BMS extends this by adding a number of control inputs that can be used for control or for hardwiring to a BMS. Both FDP2s can be configured with a variety of control functions to satisfy different applications. Custom solutions can be created to handle a wide range of application requirements.
Download the FDP2 Application Guide, this guide provides detailed information about the various solutions and functionality the FDP2 provides.
FDP2-F Fault Interface
The FDP2-F provides fault monitoring functionality with the ability to operate units in either local or central modes. Three preset modes can be set in order to lock the keypad and operate the units in Heat, Cool or Auto modes.
Group control can be achieved by networking multiple FDP2-Fs on the D-Bus network. If the master is operated in local mode then the additional FDP2-Fs act as slaves and so very large numbers of units can be operated from a single keypad. Alternatively the master can be operated in one of the central preset modes in which case all slaves operate to the same settings. If an FDP2-BMS is used as the master then the FDP2-F slaves can extend the control to a large number of units.
A pair of FDP2-Fs can be operated as a duty/standby pair with 24 hour duty changeover as well as changeover on fault. For more information on applications, download the FDP2 Application Guide.
FDP2-BMS Control Interface
The FDP2-BMS in its factory configuration is configured so that the 6 inputs can be connected to switches and variable resistances, or voltage sources such as BMS outputs, so that various unit functions can be altered. The inputs allow the unit setpoint, fanspeed, mode, louvre operation, on/off state and keypad lock state to be altered. This allows basic control of the units operation without the need for any reconfiguration of the FDP2. When switching between central and local control, an the FDP2-BMS can be configured to restore the user settings from the previous local operation.
The size of the group can be extended by adding additional FDP2-F and FDP2-BMS on the D-Bus network. For more information on applications, download the FDP2 Application Guide.
