CalUltra Controllers
A full colour LCD screen provides the user with a detailed description of the
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 CalUltra 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
CalUltra controller and the system will now monitor the UV intensity of the
system!
Power-up Sequence
On start up, the controller will run through a diagnostic start-up and the sequence will be
displayed as follows on the colour LCD:
Next, the controller checks for and initializes any optional modules that may be attached to the
system.
