CONTROLLER OPERATION 

General Operation 

The unit has 2 modes of operation, a standby mode and an operating mode that are controlled by 
the POWER key. In the standby mode, the unit is effectively off. All outputs are turned off and the 
display shows STANDBY. In the operating mode, the unit operates automatically. All inputs are 
monitored and the outputs are controlled accordingly. Pressing the POWER key will toggle the unit 
from STANDBY to OPERATE or from OPERATE to STANDBY. If power is removed from the unit, 
when power is reapplied, the unit will restart in the mode it was in when power was removed. 

Display 

The display is a 2 line x 20-character backlit liquid crystal display. System operating status and 
sensor readings are shown on this display. Set point information can, also, be shown on this 
display. 

Operating Status Messages 

The operating status of the unit is shown on the top line of the display. The following list describes 
the items shown for the operating status. 

STANDBY - The unit is in the STANDBY mode. 

DELAY 99 - The unit is in the RO start delay. The number is the seconds remaining before the RO 
pump starts. 

OPERATING - The RO unit is operating. 

TANK FULL - The unit is shut down due to a tank full condition. 

TANK FULL 99 - The unit is shut down due to a tank full condition. If the number is blinking, the 
tank full high switch has cleared, but the tank full low switch is still active. If the number is on 
steady, both tank level switches have cleared and the delay is counting down. 

PRETREAT - The unit is shut down due to a pretreat lockout condition. 

PRESS FAULT - The unit is shut down due to a pressure fault condition. 

MEMB FLUSH 99 – Membrane Flush is active.  The number is the minutes remaining in the flush 
cycle. 

CONDUCTIVITY 

The Conductivity is shown on the top line after the unit operating status. When the unit is in 
STANDBY, because of a shut down condition, the reading is replaced with ‘----’.  If the reading is 
over range, the reading is shown as ‘^^^^’ when in the OPERATE mode.
