I cannot figure this one out. The display inside says Fan Only but the bacnet point says Heating and is not writeable. This unit does not have heat. The fan shows status, no visible alarms, the compressors all show Enabled, all temps reading fine, cycled power, economizer disabled due to high OAT, DX enable set at 55. PCT won't work with this circuitboard. Grabbin' at straws if anyone has seen this before.
Model J18ZJC00F2VZZ0001
How is it controlled, thermostat, space sensor? Possibly set for thermostat only control and not using a thermostat. New unit or old unit that stopped working?
Sorry for being so brief. It's an existing unit that just will not cool this year. There is a bacnet point called TstatOnly which is true but as you can see in the pic above it has never been wired to one. I am not having any luck finding a bacnet manual for this. Will Simplicity work with this? PCT is not.

The tstat only needs changed. It’s easiest to do it via the map gateway tool, but is changeable via the joystick. It’s just a pain.
I think it’s under the control option.

Sorry for being so brief. It's an existing unit that just will not cool this year. There is a bacnet point called TstatOnly which is true but as you can see in the pic above it has never been wired to one. I am not having any luck finding a bacnet manual for this. Will Simplicity work with this? PCT is not.
When using the Map Tool, do not use PCT/CCT
Log into the map tool via web browser and then log in credentials. Then you will see the points/setpoints list.

You can also use the Simplicity software and hardware I believe, but the Map is so much easier to navigate.

Just when I thought I knew it all, I realize that I am still learning something new everyday!
The MAP Gateway creates a WIFI connection that you connect to giving you a Web UI. Without a MAP gateway you will need to use the local joystick. I think that point is writtable if using N2 but not in BACnet.
I never noticed the Tsatonly point before so I thought maybe the bms was priority. I used the joystick and looked and looked and looked and looked and looked and found it under Factory. I wonder what happened! Thanks guys.
Will the MAP Gateway allow USB or FC/SA bus connections as well? It would be nice to work on these units that have the Simplicity boards installed without the nice screen and buttons.
Ran into several JCI packaged rooftops with flashing codes, could not eliminate all the codes and had no way to view the programming last week. From what I see in the guide, you have Ethernet and RJ12 as options to view config through a laptop.

Only works with the newer boards as it plugs in with a rj12 type connector from the Gateway. The gateway can communicate with a computer using Ethernet or Wifi. https://cgproducts.johnsoncontrols.c...F/24107378.pdf
The older boards use Simplicity software with a RS485 adapter.
Is there a legacy site still alive that offers the Simplicity download? I tried some links from a good YouTube video about the software, but the York website is dead now. Seemed like free software so a bummer.
hvac69 I really appreciate the help. Was able to plug up to an RTU today and found issue stopping it from running. Would have no shot without the software.
Someone decided to disable the Cooling Mode Operation Enable point, and also ignored the VAV/CV selection message that says 1A boards and standalone units have to be set to OFF. The Simplicity software doesn't let you do a ton, but it's enough.
