Procool SP480X

How it works:

User sets the controller's on and off temps to start and stop the system. Typical start temp is about 80-85F. Off temp at or slightly above room temp. These settings can be adjusted for optimal performance. The controller has a temp sensor that should be located on or near the heat source, or can be located at the top of the cabinet for an ambient reading. This temp is displayed on the controller during operation for easy monitoring. Or, the display can be shut off during operation. (See Operating instructions)

Each of the 4 fan power connectors are numbered 1 thru 4 corresponding to the front panel LED indicators. When the LED's are on that fan will be on. When the LED's are off those fans will be off.
Global setting: Front panel LED's for fans 1-4 are all on.
Individual setting: Front panel LED on for one fan at a time.

Programming Temperature profiles:

Set the Global range higher than individual fan settings. If the highest individual temp is for example 90F set the Global temp to 92F or higher. If the Global temp is set to start at 85F then any fans set to start at 90F they will start when the Global start point of 85F is reached. Likewise if using the Global setting, make sure all individual settings are set outside of the Global range. The same rule applies for the OFF settings.
