At any point during this sequence, the audible chirp can be deferred by holding the controller button down for a
period of five seconds. The screen shown below will appear for five seconds indicating that the audible defferal has
been activated and then the system switches back to the current lamp change or lamp expired screen. This audible
deferral will last for seven days after which then the alarm will sound once again. This audible deferral feature can
be activated as many times as you wish. PLEASE NOTE: During the condition of lamp expiration and audible
deferral, the water may be unsafe for consumption and should not be consumed without another form of
disinfection.
Lamp Countdown Reset Sequence
After changing the lamp on the CalUltra system, the controller must be reset in order for the system to begin its
countdown function on the newly installed lamp. To perform this reset, you must firmly depress the button on the
front of the controller and then manually plug the power cord back into the wall outlet initiating power to the unit.
Keep holding down the button for five seconds until you hear an audible chirp indicating the controller has reset
the internal timer. Release the switch and the lamp countdown feature has now been reset. The following two
screens will be displayed during this process.
Failure Modes (if applicable to the system)
The CalUltra controller continuously monitors your UV system and if there is a problem with the system the
controller will provide both a visual and audible signal indicating the specific fault that may be adversely affecting
the operation of your system. The fault conditions are listed in a priority sequence as follows:
LAMP FAILURE:
If at any time during the operation of the system, the UV lamp fails
to be illuminated, the controller will return both an audible and visual signal indicating
lamp failure. In addition, a constant audible buzzer will sound during lamp failure.
