FDP3 Interfaces

The FDP3 range of interfaces provide monitoring and control solutions for Toshiba SMMS, SHRM and Digital Inverter air conditioning systems. This supercedes the previous FDP2 range of products

FDP3 interfaces are the basic building block for creating low cost air-conditioning control solutions. A single FDP3 interface can monitor and control up to 8 indoor units as a single group, multiple FDP3s can create more complex groupings.
