Pretreat
If the pretreat input becomes active (closes) and stays active for 2 seconds,
the unit will shut down in a pretreat lockout condition. PRETREAT will show
on the display and the unit will remain shut down as long as the pretreat input
is active.
High Conductivity
If the Conductivity reading exceeds the limit programmed the Cond Limit
Setpoint for the delay programmed in the Cond Delay Setpoint, the alarm
lamp will light and the HI COND warning message will show on the display.
This warning will clear when the Conductivity drops below the Setpoint.
When the High Conductivity warning message is active, the MRO will divert
the PRODUCT WATER to drain (through the Reject hose), until the Product
water conductivity goes back into the acceptable quality range.
Direct Feed
This is the setting that installation of this new CPU enables. Setting this to “1”
allows for pairing with the Heatsan disinfection system. This changes the
operation of the “tank full high” and “tank full low” inputs. “Tank full high” is
used to indicate that the Heatsan is in operation while “tank full low” is used to
turn the RO on and off when water is required. Changing this set point to “0”
allows for the RO to operate as if the CPU was not installed.
