I really would appreciate written directions, am I required to use my phone?
Could you please let me know the product model?
ISV-200W, AC120 60HZ 1000W,
I don’t see a Model number on anything, hope this is enough, thank you
If it is a simple function, the ISV-200W can be set by the buttons.
There is a description of the buttons in the manual: ISV-200W User Manual in English 20200715.pdf - Google Drive
But setting it through the app is faster and more convenient. If you have problems connecting to WIFI, maybe this thread will be helpul: Q&A: Inkbird WIFI product connection troubleshooting
