(3) Block setting
The block comes in two types, operation block and charge block.
The operation block is an aggregate of groups, and it is possible to set a different model group
for the same operation block.
The charge block consists of an aggregate of operation blocks.
* The blocks controlled with the AG-150A/G-50A browser are the same as the operation blocks.
Operation blocks extending over AG-150A/G-50A can be set only with the integrated software TG-2000A.
The operation block should be set individually for the K-control model, A-control model, DIDO
controller, LOSSNAY and free plan indoor unit.
(4) Notes on using K-control models
When using a K transmission converter (model name: PAC-SC25KA, PAC-SC25KAA(-E)) to
manage K-control models, take note of the following. See the documentation provided with the K
transmission converter for more detail.
The address of the K transmission converter will be the smallest address of the K-control model
+ 200.
Set the K control model addresses so that they are larger than the M transmission model addresses.
When setting a group containing K-control models, make the group number the same as the smallest
unit address in the group.
K-control LOSSNAY models are not applicable.
(5) Notes on using A control mode
Use the A/M-NET Adapter (model name: PAC-SF48MA(-E)). Set the group to “Group with only
A-control”.
(6) Countermeasure when an error occurs
Note that each control or function may not operate properly when rebooting (*1) or when a fault
occurs in the central controller AG-150A/G-50A or other controllers and so on. Since each error
is displayed when it occurs, it is recommended to solve the faults quickly.
*1 Indicates that the system is restarting.
(7) Notes on charge system
This charge system does not actually calculate the power consumption by each air
conditioning unit. Rather, it helps calculate the capacity output of each air conditioning
unit, using the unique apportioning method developed by Mitsubishi.
Mitsubishi shall not be held responsible for any problem or damage resulting from the
use of TG-2000A, including but not limited to the cases as described in section (8) below.
If there is a group that is not set in the charge block, the electric power amount for that group will
not be included in the air-conditioning charge. If there are groups which require charging to be
divided, set those groups as operation blocks or charge blocks to accomplish this.
Some older M-NET control indoor units are not compatible with the charge function.
When the system is changed or the air conditioner is extended, which may require address
changes, the charge calculation may be affected in some cases.
Executing such changes or extensions are recommended after gaining approval from the
building owner(s).
Irregular processes, such as repeated apportioning of power or non-apportioning of power (*1),
may occur due to communication errors with the central controller AG-150A/G-50A , PLC or PI
controller , etc. If the rates are not apportioned, a recovery process must be executed with the
charge maintenance function, etc.
*1 For power apportioning billing function's (Direct read in of power value into computer) function
The power rate accuracy relies on the watt hour meter. The measurements for the gas, etc.,
also rely on the meters, so an error could occur in the accuracy during operation.
