Things You Might Need to Know
• When the controller is first plugged in, it may display a flashing Err 3
and scrolling "Call Dealer for Service" message. This means that the
controller is rotating to the home position. The Err 3 will clear when the
control reaches the home position.
• The preset default time of regeneration is 2:00 AM. If you want to
change it, see the Level II Programming section.
• The controller can be programmed to regenerate on specific days of
the week. See Level II Programming section.
• If electrical power is not available, the camshaft can be rotated
counterclockwise by hand if the motor is removed.
• The Ultramax series controller sends commands to the motor for
camshaft movement. However, water pressure/flow are required
during the regeneration cycle for backwash, purge and refill, and brine
draw to actually take place.
• Make sure control power source is plugged in. The transformer should
be connected to a non-switched power source.
