Setpoint Screen Index
The available Setpoint Screens for the MUA II Controller are listed on
the next few pages by sequential screen number. When each MUA II
Controller is confi gured for the fi rst time, it is best to start with screen #1
and proceed to each Setpoint Screen in numerical order until you have
viewed all available Setpoint Screens. This ensures that you have seen
all of the available MUA II Controller Setpoint possibilities and have
the opportunity to change or accept the defaults for each screen. Once
the unit Setpoints are confi gured and you decide to change one of the
screen options, it is helpful to know what screen number contains the
confi guration you wish to change. With this in mind, the following is a
