Product Description
The RBC-TSI1 is a versatile interface for Toshiba air conditioning units, offering a wide range of external control
facilities. The unit attaches to the TCC-NET A+B network. The interface is network powered and may be used with or
without a remote controller being present. Up to eight indoor units may be monitored and controlled as a group by a
single RBC-TSI1.
Hardware Interface:
Six analogue control inputs selectable as resistance or 0-10v D.C. Two relay outputs for ‘Run’ and ‘Error’ rated 24v
0.1A
Serial Interface:
RS-485 serial Modbus connection with slave addresses from 1 to 254 and configurable baud rates and parity.
Modbus may be used for monitoring and control or to allow the
operation of up to sixteen units in a ‘Master/Slave’ configuration.
Operating Modes:
Several modes of operation are available including special modes for energy saving and hotel applications.
Modes are selected by a link and bit switches.
AVAILABLE MODES:
1.
Standard operation with the facility to interconnect up to 16 interfaces as a ‘Master/Slave’ group.

Appendix A: - Definitions
The following nomenclature is used throughout this document.
Modbus Holding Registers H-nn:
These are the function 3/6/16 registers with offset nn.
They are the same as registers 40000 + nn + 1
Function 3 is used to read the registers
Functions 6 and 16 may be used to send values to them.
Modbus Input Registers I-nn:
These are the function 4 registers with offset nn.
They are the same as registers 30000 + nn + 1
Function 4 is used to read the registers
These registers may not be written to.
e.g. H-15 is equivalent to 400016 and is accessed for read/write
by Function 3/6/ 16 using offset 15.
I-24 is equivalent to 300025 and is accessed for read by Function 4 using offset 24.
Hardware Inputs:-
This means either the analogue inputs A1 to A6 or the internal registers H-51 to H-59, depending which set is selected
by switch S1-6.
The analogue inputs A1 to A6 may be configured as Voltage (0-10v) or Resistance inputs.
Switch Settings Diagrams:-
The switch setting diagrams in this document use the following convention:
In the diagram opposite:
S1-1 to S1-4 are shown in the OFF position
S1-5 & S1-6 are shown in the ON position
S1-7 & S1-8 are shown as selectable

In Eco Timed Fan mode the unit will, following switch on, operate with the parameters set on Hardware Inputs A1-
A4 / H-51 to H-54 with A5 controlling On/Off. After 5 seconds the setpoint may be changed if required from the RC.
Once the time has elapsed the unit will change its mode to Fan mode.
The sequence may be re-started by cycling the unit Off / On with A5, Modbus or using the RC. The sequence may
also be re-started by linking the A6 input for 1 second. On restart the setpoint will revert to the A1/H51 value and
may again be changed from the RC after 5 seconds.

The Eco Fan Band mode allows the setting of two set points using the Hardware Inputs. When the RA is below the
low set point the unit will operate in Heat mode with a set point of 30 degrees. When the return air temperature rises 1
degree above the low set point the unit will change to Fan mode. If the RA rises to the upper set point then the unit will
operate in Cool mode with a set point of 18 degrees, reverting to Fan mode when the RA falls to 1 degree below the
high set point.

The Hotel mode provides for ‘Occupied ‘and ‘Unoccupied’ settings. The settings used may be selected with the A6
input. When the A6 input is active (linked) the ‘Occupied’ settings are used initially with the user then being able to
change the settings using the RC. If A6 is open then the unit uses the ‘Unoccupied’ settings which are periodically
refreshed to force the settings. In either mode the A5 input operates as an On/Off input and may be connected to a
master switch, a window switch or both. Following an Off – On sequence on A5 the settings will be returned to the
previous values unless the occupation state is also changed during this period. Changing of the occupation state
always results in the basic ‘Occupied’ or ‘Unoccupied’ values being re-instated.
