Dear customer,

To replace your old controller, you can find the attached photo for reference. 

Please let us know if it works.

Thanks,

Hint:

Not using 2 of 6 zones too due to yardwork. I just changed the schedule and removed the zones from the schedule. The 2 unused zones are not watered automatically temporarily.  Note: I did not remove the unused zones from the system and did not disable them. This allows me to test the zones manually by manual watering the zones on my phone on the spot. It helped me very well adjusting the new sprinkler heads without walking back and forth to the system / taps all the time. 

Dear customer,

Thanks,
