Terminal integration steps 

The Toshiba adapter is programmed to align the outdoor unit with the correct indoor units. 

In order to do that, we will run a test in the toolbox terminal. 

1. Type:

ostat

2. You should receive the response:

Y1.000 Undefined
OK

Look up the outdoor unit model from this list:

link Y1.100 SMMS
link Y1.100 SMMSe
link Y1.100 SHRMe
link Y1.100 SMMS-Mini
link Y1.100 SMMSu

3. Copy the correct outdoor line to the toolbox terminal. For example:

link Y1.000 SMMS-Mini

4. You should receive the response:

OK

5. Boot the device by unplugging and replugging the power cord/type in the toolbox terminal:

boot 2

Now, you will receive a different response when you type the "ostats" command in the toolbox terminal
