Had to replace the cartop SRU board. Got the new board from Smart Rise, preprogrammed for the job. But now the Controller is only running the S1 speed profile (50fpm) and does not move into S2 or S3 speeds. I can set the S1 profile to run at contract 350 but it shoots through the DZ during slowdown on 1 floor runs. It runs fine with S1 at 175 to 200 becasue it has time to slow down as long as the distances are set up right. But this is a work around and not a solution. I refuse to reduce the speed just becasue the Smart Rise tech said this will make it run. That's not what the customer paid for. Has anyone else experienced issues like this after replacing the car top or any SRU? Waiting on further tech support but thought I'd check here for any past experiences with the same issue.
