TCB-PCNT30TLE

The device is intended for use on all the DI/SDI units other than the KRT High Wall, which is supplied with the adaptor built in. The device is designed to allow Network devices such as Central Controllers and BMS systems to be interfaced.

 

Application

The device consists of a small PCB, which should be installed within the indoor unit and would typically be used where the indoor unit/units will be interfaced with a Central Controller or any other network device, such as a BMS system. One device is required for each indoor unit or group of indoor units. Where indoor units are grouped together they will be assigned with one address on the central device and will consequently all receive the same operational instructions.

 

Connections

The device connects to the indoor unit PCB via socket CN50 and will provide two terminal network connection designated U3 & U4.

Where multiple devices are to be installed it is necessary to set one unit with a 100ohm termination resistance. This would normally be on the device connected to the unit with the lowest network address. The resistance being set by SW01 bit being set to ON.

When the device/devices have been installed and a termination resistance applied it is then necessary to apply a unique network and refrigerant line address to each unit.
 

Addressing Procedure

The address setting is carried from a standard RBC-AMT21/31E remote controller.

Where units do not have standard remote controllers installed, one should be temporarily attached in order to carry out the configuration process.

Accessing the Engineers configuration menu

Press Set CL & Check Simultaneously for 4 seconds.

Navigate to menu item 12 (refrigerant line address) using the Temperature Set Buttons.

Set a unique line address using the Timer Set Buttons and then press SET.

Navigate to menu item 03 (network address) using the Temperature Set Buttons.

Set a unique network address using the Temperature Set Buttons and then press SET

Press the CHECK button to complete the setting process

Generally speaking the refrigerant line address would mirror the network address, however this would not be the case with grouped units, which would have the same network address but different line addresses.

 

Limitations

It is recommended that 1.5mm2 2-core screened cable be used on all networks up to a maximum of 500Mtrs in length.

The KRT range of units do not require adaptors as they are supplied with U3 & U4 connections and also have a termination resistance facility on the indoor PCB. The termination resistance being set by SW01 bit 1 being set to ON.
