Fixed interval mode means that the average demand value in T minutes is calculated 
for each T block, and then the value is recorded. A month's demand is automatically 
recorded at a fixed time. 
Sliding interval mode means that the average demand value of the last T minutes is 
calculated, and then the value is recorded. The demand of a month is automatically 
recorded at a fixed time. 
 
*RS485 version: 
For the RS485 version, the MTA36R, the modbus identity is configured differently. A 
table with the different identities according to the position of the tab at the top is 
shown below: 
 

TAB POSITION

11 

12 

14 

13 

 
To change the identity of the 0 position it is necessary to write it from position F. To do 
this: 

1.

 

The tab is positioned in position F. 

2.

 

Using the software, the device is connected with the identity 0. 

3.

 

Enter the Configuration->Basic configuration menu. 

4.

 

Enter the desired identity and press the save button. 

5.

 

In the software, the communication with the device is cut off. 

6.

 

The tab is changed to position 0. 

7.

 

Using the software you connect the device with the desired identity. 

 

3º Configuration of the tariffs. 

 
It is possible to configure two different tariff days with time intervals and up to 4 
different tariffs.  
It is also possible to configure which day of the tariff is each month.
