1. Application
The VRF Dx-coil Interface comes with DX-coil Controller which has 3 types of application(DDC type,TA type,TF type).
Application types can be set and enable system to response according to the application.
・TA type :(Main application target – Room temperature conditioning)
The VRF Dx-coil Interface(TA type) enables TA control of Toshiba Outdoor units connected to
a DX COIL (with a field supplied AHU). It is compatible with either a Toshiba VRF system.
・DDC type :(Mainly discharge air temperature control linked AHU system.)
The VRF Dx-coil Interface(DDC type) enables BMS capacity demand control of Toshiba Outdoor units
connected to a DX COIL (with a field supplied AHU). It is compatible with either a Toshiba VRF system.
・TF type :(Main application target – Ventilation)
The VRF Dx-coil Interface(TF type) enables TF control of Toshiba Outdoor units connected to
a DX COIL (with a field supplied AHU). It is compatible with either a Toshiba VRF system.
Settings for each type (TA, TF, DDC)
Set with the SW501 switch on the control P.C. board MCC-1777.
TA Type : SW501 all Bit=OFF
TF Type : SW501 Bit2=ON
DDC Type (0-10V) Stepped Control:SW501 Bit3=ON
DDC type (0-10V) Linear Control : SW501 Bit3,Bit4 = ON
