Control Applications

Fan Coil Unit (FCU) – [Application (AV12) = 4]

Function: Control of a Fan Coil Unit with a single or multi-speed fan.

DNT-T221-FCU I/O (Outputs 1 & 2 are Analog, and Output 3 is a Triac)

Input AI2 when Interlock option is not selected, i.e.

(



=No)

may be used as a temperature input.

Although this combination may be selected, the mode of operation does not offer a valid sequence.
