The indoor unit is equipped with an automatic restart facility that allows the unit to restart, at the last set operating conditions, after a power failure. The operation will resume without warning three minutes after power is restored. This feature is not set up when these systems are shipped from the factory, therefore it will need to be activated by the installing company.

Generally the process is the same for all RAS products since approx 2001 and is as follows:

To initiate auto restart:

1. Turn the power on. Green On/Off light will flash.

2. Set the system to operate using the remote controller. Green On/Off light will be on constantly.

3. Press and hold down the temporary button for three seconds.

4. The indoor unit will bleep three times to acknowledge set up. In most cases the green light changes to orange.

5. The system will continue to operate during this set up.

6. After set up the system may be stopped using the remote controller.

To cancel auto restart:

1. The system is operating. Green On/Off light will be on constantly.

2. Stop the system operating using the remote controller. Green On/Off light will extinguish.

3. Press and hold down the temporary button for three seconds.

4. The indoor unit will bleep three times to acknowledge cancellation.

5. The system will have stopped operating.

This feature cannot be set if the timer is in operation.

The louver will not swing, if it was previously set, when the system auto restarts.

Fault Codes – RAS “N” Series

Do Not turn off the power supply before reading the fault codes, doing so will clear the diagnostic memory. Caution

must be taken when removing the access covers as high voltages are present.

Fault codes are displayed through the LEDs flashing at 5 times per second. Note, the green LED will flash once per second when the system is initially powered.

More specific codes may be obtained, while in the fault mode through the wireless controller

1. Press CHK to enter service mode

2. Navigate through TIMER  buttons until all LEDs flash, accompanied by the internal buzzer – compare the

displayed code with the table below

3. Press CLR button to clear the existing fault code (controller displays 7F)

4. Press ON/OFF button to exit service mode.

Common Sensor Characteristics

There are eight commonly used sensors in the RAS and RAV systems.

Ta = Return Air Sensor; indoor unit Tc = Coil Sensor; indoor unit TL = Liquid Pipe Sensor (fan speed); outdoor unit TE = Heat Exchange Sensor (defrost); outdoor unit Td = Discharge Pipe Sensor; outdoor unit To = Ambient Ts = Suction Tk = Oil sensor

The Ta,Tc,TL and TE sensors all share the same resistance versus temperature characteristic. They differ however in electrical connections and sensing head style, therefore it is important to quote the full model type number when ordering any replacement sensors. The Td sensor has a different resistance characteristic because its sensing range is that much higher than the others.

Outdoor Fan High Static Pressure Setup

This function is used when connecting a duct to the discharge outlet of an outdoor unit. To setup turn ON the DIP switch [SW10, Bit 2] provided on the interface P.C. board of the outdoor unit. This function must be enabled with every discharge duct connected outdoor unit for both of the header and follower units. It is necessary to increase the speed of the propeller fan units on the outdoor fan to allow the installation of a duct with a maximum external static pressure not greater than specified in the table below. If a discharge duct with a resistance greater than 15 Pa (1.5 mmAq) is to be used, enable this function. The maximum external static pressures of base units are shown below: -

SMMS(i) Model MMY- MAP0804* MAP1004* MAP1204* MAP1404* MAP1604* Maximum external static pressure(Pa) 60 60 50 40 40 (*) Outdoor unit air flow (m3/h)

Group control

 Indoor units may be supplied from any phase  Up to 8 indoor units per group  Automatic addressing  Any indoor unit may be designated as the “master”  Pre-heat indication  Filter indication

Automatic addressing

This takes place when power is applied and can last up to 5 minutes – the address will be selected automatically. If a replacement indoor PCB is fitted, the missing address will be re-applied. The powered controller screen shows the demarcation lines – and does not indicate that the system is either configuring itself – or is ready to use. If the remote temperature sensor is selected (configuration item 32), the associated symbol will appear when the system is ready for use. If a 9

indoor unit (which can be a protocol converter) is added to a group, the controller will continue to show the demarcation lines. Adding a system to an existing group (or powering a group up at different times) will require manual configuration (the fault codes will provide guidance).

Identifying an indoor unit

 Stop operation  Press TEST and (external) FAN for 4 seconds  ALL is displayed  Indoor fans of the entire group are now energised  Press UNIT to scroll through group  Indoor fan of selected indoor unit runs  Press TEST to exit.

Test operation

 System must be stopped  Press TEST for 4 seconds  Controller displays TEST  Press the ON/OFF button to start operation  Select MODE of operation  HEAT or COOL  Press the ON/OFF button to stop test  System will automatically revert to normal operation after 1 hour  Press the TEST button to leave TEST function 

Quick Reference Guide

To assist service engineers working on Toshiba air conditioning equipment, there is a large quantity of data available via the standard remote controller, either the RBC-AMT32E or the RBC-AMS41E, this data is NOT available via an Infra Red remote or the RBC-AS21E2 simplified remote controller. Accessing the data is a simple process of pressing a sequence of buttons on the remote controller.

Fault Code Guide Current fault codes are displayed automatically on the left of the remote controller, (Four figure display in Black) fault code history can be accessed by pressing “TEST & SET” together and holding for 4 seconds. Each controller will hold four fault codes per unit controlled, the first displayed fault code is the youngest and the fourth will be the oldest. To scroll through the faults use the

“TEMP”

buttons.

Terminology

Terms for explaining DI/SDI used in section are redefined to: Indoor Unit No. N-n =outdoor unit line address N (Max30) –indoor unit address n (max64)

Group address 0=single (not group control)

1=Master unit in group control 2=sub unit in group control

Master unit:

The representative of multiple indoor units in group operation sends/receives signal to/from the remote controllers and sub indoor units. It has no relation with an indoor unit which communicates serially with the outdoor units. Also this unit communicates with the central controller. The operation mode and setup temperature range are reflected on the remote controller LCD. (Except air direction adjustment of louver)

Sub unit:

Indoor units other than master unit in group operation. Basically, sub units do not send/receive signals to/from the remote controller.

Header unit (Representative unit) (Master twin):

This unit communicates with the indoor unit (follower) which serial-communicates with the outdoor units and sends/receives signal (command from compressor) to/from the outdoor units as the representative of the cycle control in the outdoor units of the identical line address within the minimum unit which confugures one of the refrigerating cycles of twin.

Follower unit (Subordinate unit) (Sub twin):

Indoor units excluding the header unit in Tw in. This unit communicates with Header indoor unit in the identical line addres s and performs control synchronized with Header unit. This unit does not perform the signal send /receive operation with the outdoor units. No judgement for serial signal error.

Address re-setup for group control

After turning on the power and finishing automatic address setting, check the Indoor Unit No using the wired remote controller. If the line address is not unified in the devices in a refrigerant line, unify the line address using the wired remote controller. If group control is used, assign th e g roup ad dress “1” t o an y o ne of the indo or units and “2” to the rest of the units. Confirm that each indoor unit in a gro up has a unique Indoor Unit No (E08 error

is not indicated on the wired remote controller).

Standard configuration (One outdoor unit)

In this case, address setting can be made by using auto addressing.

Connection and Address re-setup example for central control

When controlling the super-digital inverter and the digital inverter, the adaptor named “1:1 model” connection interface (TCB-PCNT30TLE2) is necessary.

“1:1Model” Connection Interface TCB-PCNT30TLE2

SDI series 4 4-way discharge cassette type, etc. need metal case TCB-PX30MUE additionally for fixing. Some of Hi-wall Type does not need “1:1Model” Connection Interface. Please refer to installation manual of each model.

Cabling connection of control wiring

Attach an adaptor per 1 group in the group control operation (including individual control). Connect the adaptor to the Master indoor unit in the group control.

After automatic address setup, it is necessary to change the line address from the wired remote controller for each system.

Reason :

After automatic address setup, all of the line addresses will become “1” except in a group control and then a duplicated address error “E08” will be outputted.

When the central control is performed for indoor units using twin control in a group operation, it may be required to change the group address. (Adapter is attached to the Master indoor unit.)

Reason

: The central control device communicates with each individual indoor unit, the Master indoor unit of the group

control and the Master indoor unit of the twin control. However, as the address is automatically set up, which unit will become the Master unit is indefinite. Therefore if the unit attached with adapter does not become the Master indoor unit, the central control function will become unavailable.

Network Addressing DI/SDI and VRF Systems

1. Set up address after the wiring has been completed.

2. “1:1Model” Connection Interface TCB-PCNT30TLE2is necessaryfor DI/SDI for central control. Some Hi-wall

Type do not need “1:1Model” Connection Interface. Pleaserefer to the installation manual of each model. Connect the central control devices to U3/U4 wires of the central control system.

3. When “1:1Model” Connection Interface is used for the group control or twin, triple or quad

system, the interface

must be connected to the Master unit of the indoor unit. (Connection to Sub unit is unavailable). One “1:1

Model”

Connection Interface per one group.

4. In group operation, be sure to turn on power supplies to all indoor units in group control within 3 minutes.When

power supply of the Master unit is not turned on, there is a possibility that the Master unit exchanges with Sub unit. (If Master unit is exchanged, the central control is unavailable.)

CAUTIONS

Address setup procedure (when using DI/SDI only, or using DI/SDI and VRF)

When an outdoor unit and an indoor unit are connected, or when an outdoor unit is connected to each indoor unit respectively in the group operation even if multiple refrigerantlines are provided, the automatic address setup completes with power -ON of the outdoor unit after group construction check (refer to the note below). The operation of the remote controller is not accepted while automatic address works. (Approx.4 to 5 minutes)

Note)

If group construction is abnormal, the automatic address sequence starts automatically. Normal condition is below.

1. There is no duplicated indoor unit address.

2. There is no invalid indoor unit address.

3. Individual unit and master/sub units are not intermingled.

4. Only a unit for Individual.

5. A master indoor unit and 1 or more sub indoor units for group.

Integration with AI Network Control

TCC-net models use a different language to AI – however a TCC-net group can be linked to an AI network, by the use of a protocol converter. This device is not standard and should be fitted on site – a group requires only one protocol converter to communicate with a network. An LED flashes to indicate communication with the network. The Protocol converter provides terminals X-Y for the network connection – it also has the 7-way DIP switch used to give a network address – the method is identical to that used for AI indoor units. The network address may also be set by a wired controller from the configuration menu. The protocol converter is counted as an indoor unit – only 7 indoor units may therefore be group controlled in this way.

Second Controller

 Options available

 2 x wired controllers  1 wired + 1 infra red controller

 Full group control from either  Connection may be anywhere within group  Changes updated

The sub-controller must be set – this can be done from either controller. The choice of sub-controller makes little difference unless it is required to act as the temperature sensor

Temperature Sensing

Both infrared and wired controllers are able to supply a temperature value to the indoor unit. This may be more representative than the standard, return air sensor but is not available from sub controllers of either type. To set the room sensor:

 Infrared controller – press MAIN SENSOR  Wired controller – selected from configuration menu

Should the infrared controller lose contact with the indoor unit, return air temperature control will automatically resume. A further option for remote sensing is available – the remote sensor. This is connected to terminals A-B whether or not a wired controller is used. The indoor unit must, in this case, be set to use the standard, return air sensor – this sensor automatically takes over in this case. This value will be used to provide control to all indoor units within the group.
