5.0 Operation
5.1 Startup
Do not add chemicals to the feeders until all
start-up operations are completed. Using a
DPD test kit, manually adjust and balance the pool to acceptable ranges. Automation
should be used to maintain
chemical
levels, not to balance a pool that is out of
acceptable ranges. With the controller in the OFF Mode, turn the filter pump on and
check for leaks in the system and flow through the flow cell. The flow lamp will be
illuminated if the controller has power, it is connected to the flow switch and there is
adequate flow. If a flow switch is not attached, the flow lamp will be illuminated if there is
a jumper in the flow cell terminal. Using a flow switch is always recommended.
5.2 ORP setting
Press and release the controller MODE button until the AUTO light is off. Then select the
desired set level and feed time cycle.
5.3 Operating mode
Press the MODE button until “AUTO” is lighted. This is the operational mode for the
controller. The controller must be in this mode to maintain the desired parameters.
Timed feed settings: T
he feed lamp will flash during the feed time and be constant during
the delay time of the feed cycle. Feed lamp will be active
until set-point is reached and
feed cycle is completed. If over feeding is occurring, consider a shorter feed cycle.
Constant feed setting: T
he feed lamp will flash while feeding.
Power will be supplied to
feeder until set-point is reached.
The feed lamp will not activate when the alert lamp is on (ORP below or above the alert
settings).
Low feed rates can cause the feeder to lag or feeding to be extended. A high feed rate
can result in too much chemical being added.
5.4 Reset to factory default
The controller can be reset to the default factory settings by using the steps below.
Note: ‘Re-Set’ button is unmarked and located directly to the right of Feed Time button.
A. Turn the controller Off:
Press ‘MODE’ to turn ‘Auto’ light off.
Hold ‘MODE’ button until display reads “oFF”.
Release the ‘MODE’ button. Only the flow light should be on.
