This NAE and UNT set up were working when removed.
The NAE is 3511-1 and there are 7 UNT 111 boards included.
Recently removed from a working environment, 3 of the roof top units were on thermostats and one had no low volt power however when hooked up at home the unt 111 boards power up and show up online.
Unfortunately I cannot help with installation programming or setup questions.
Please check out the pictures and offer accordingly.
These used items are sold as is, however i just connected them and they all came online as shown in pictures.
Cannot be shipped to P.O. box, must have a physical address for shipping.
