Installed time delay relays for both rooftops on compressor number two, this should allow the machine to run at 25% capacity for roughly 3 and 1/2 minutes to allow for better humidity removal. Monitored both units and confirmed that they still are only running at half capacity, I can extend the delay time for compressor number two if necessary. I did not want to make too many adjustments at one time until we have a better idea of how the machine is performing. The humidity dropped 2% on each floor once I made the changes. We can also install time delay relays on compressors number 3 and 4 if necessary. I would like to monitor the operation of the unit before we make any further decisions in regards to adding additional parts.
