BWT control display
A full colour LCD screen provides the user with a detailed description of the UV
system’s performance in addition to providing any applicable fault messages and
system diagnostics. The controllers used in both the un-monitored and monitored
systems are identical. The difference is that the monitored series of products include
a UV intensity monitor. All BWT controllers include an “infinite expandability port”
located on the right side of the controller. Simply plug in an optional UV sensor
module into the expandability port of a BWT controller and the system will now
monitor the UV intensity of the system!

On start up, the controller will run through a diagnostic start-up and the sequence will show the power-up

Next, the controller checks for and initializes any optional modules that may be attached to the UV system.
