Ciller command ON/OF from T3-NANO

Hi,

I can read data from chiller like :
10 VAR1 = 122929AI1
20 VAR2 = 122929BI1

But I cannot switch ON and OFF the chiller even I can do it with YABE.

The code I tried is like this :
30 122929BV2=1
30 122929BO2=1
30 START 122929BO2

The team can work on this right after we return from the local holiday, Oct8.
