The DFC-304R3-240 Fan Coil Controller is a 

line powered, fully programmable (via GCL+) 

Native BACnet

 Application Controller that 

communicates using the BACnet MS/TP 

protocol. Direct 240 VAC line voltage terminal 

connections are provided for one, two, or three 

speed fans (up to 1 HP).  

The binary model, with additional 4 triac 

outputs, covers a wide range of Fan Coil Unit 

applications, including two and four pipe fan 

coils.  And room temperature can be a 

standard 10K sensor or a BACstat II 

connected via a secondary LINKnet network 

and 24 VAC power out connection. 

 

Important Information  

 

 

This controller has terminals for connecting 240VAC (Class 1, Line Voltage). The terminals are 

safety rated, however this controller may have to be mounted in an enclosure if it is not
