CONTENTS

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

FAN interlocking control by external input
Analog Input 1 (4 - 20 mA)
・FAN mode is switched by external 4 - 20 mA input.
・Both FAN control with 4 - 20 mA input and FAN mode change with remote controller are valid, but boost
priority is given.
・The FAN priority control is switched by the DN setting of [4A0].
0000: Default (no change in FAN mode by 4 - 20 mA input)
0001: FAN control by 4 - 20 mA input, but priority is given to FAN control from the outdoor unit
0002: FAN control 4 - 20 mA input with priority
・The FAN mode switching threshold value for 4 - 20 mA input can be changed in the DN setting
* The change in FAN speed with 4 - 20 mA input is also reflected in the 0 - 10 V output of AO1 / AO1.

・To ease the integration of the Dx-coil with the DDC the capacity control is able to operate with a
STEPPED or LINEAR function from the analogue input.
・To select either a STEPPED(default) or LINEAR response, from the analogue input, use
SW501 bit4 located on the DDC(0-10V) interface P.C. board(MCC-1777)
AI4 Nothing Cannot be used.
Analog Input 2 (DC 0 - 10 V)
・ Capacity control signal(analogue input voltage) will be used as the main control value for the compressor frequency.
・ The control of capacity may not be able to be performed according to the state of an air-conditioner
(During oil recovercontrol, defrost etc.).
１）Capacity control 0-10V（Overview of capacity control）*
*There are possibilities of thermodynamic and/or mechanical limitation from many factors. which may affect our system's heat pump cycle
(refrigerant cycle) during operation. Hence, there is a possibility that the capacity output may be different from capacity control setting.

・Used by switching functions with settings of Code No. (DN Code).
・Notice code is continuously issued while input signal is ON.
・201 is displayed in the Notice code history when there is input in DI4.
＊Notice code is a function dedicated to TU2C-Link communication.
Set data corresponding to Notice code to be used to one of
Code No. 180 to 189, in accordance with following table.
In case where data other than 0000 is already set, set to other
