Push Button Interface
Three separate silicone momentary contact buttons for
Light (I), Moderate (II), and Heavy (III) skimming modes
and a Start Button for testing and immediate operation.
Built-in LED’s behind buttons indicate mode chosen and
blink during operation.
Startup
**Before applying power to unit, always make sure tank is full of
water**
1. Upon applying power to the unit, all lights will activate
for 1 second.
2. If the (I) Button blinks 4 times, the unit is operating in
Default Mode.
3. If the (III) Button blinks 4 times, the unit is operating in Extreme Mode.
4. The last setting chosen will remain illuminated. See corresponding chart (page 4) to determine skim
time and frequency chosen.
Operation
1. During a skim cycle, the skim setting will remain illuminated.
2. The Start Button will light up during a skim cycle.
Error Codes
In Error Code events, all four lights on the Push Button Interface will flash in one of the following
sequences:
1. 3 Flashes - There is no information coming from the thermistor. Check to ensure the wire is properly
connected to the board and there are no frays in the wires. If wiring is correct, replace thermistor.
2. 4 Flashes - The thermistor is reading an extremely high temperature inside the tank, meaning the
water level inside the unit has dropped below the heater. Check to verify the tank is full of liquid
and cycle power. If error code repeats despite the heater sitting in liquid, replace the thermistor.
3. 5 Flashes - There is a voltage out of range on the printed circuit board. Verify that all wiring
connections are secure and there are no frayed wires inside the Center Module. If wiring is correct,
printed circuit board (PCB-2) will need to be replaced.
