The topside control panel has buttons which you press to set the temperature, initiate the filtra-
tion cycle, turn the light on, and activate or deactivate the pump(s) and blower. The Topside
control panel display responds to let you know you have pressed a button, and that the selected
function has been performed.
Temperature Control (Up & Down Buttons)
These keys are used to set the temperature of the water. As soon as you press one of these keys,
the display will show the current set point and will keep showing it for 5 seconds after releasing
the key. Pressing the keys will either increase or decrease the current set point. The Set Point
LED on the display tells you if the display shows the current set point or the actual tempera-
ture of the water.
The water temperature can be adjusted in 1 degree increments from 15 to 40°C (59ºF to
104ºF). After a power down, the default set point is 39°C (102ºF).
When the water temperature is 0.5ºC lower than the set point, the heater will come on until
the water temperature reaches the set point plus 0.5ºC. The Heater LED on the display will
blink when the system calls for heat and will come on when the heater is actually turned on.
Pump 1 Button
This key is used to turn Pump 1 on in the sequence Low, High, then Off. A built-in
20-minute timer will shut the pump off unless the user does so manually. The pump
LED on the display will be on when the pump is running. When there is a Heat demand, a
Cooldown period (30 seconds after heater turns off), or when pump is running because of a
filter cycle, the controller will turn the pump on Low speed. Then, if the user presses the Pump
key, Pump will go directly into High speed.
Pump 2 Button
(Optional)
This key is to turn Pump 2 on in the sequence of High, then Off. A built-in 20-minute
timer will shut off the pump unless the user does so immediately. The LED beside the
the Pump 2 logo on the display will be solid when the pump is running. When there is a filter
cycle (first phase) the controller will turn the Pump 2 on in High speed for one more minute.
Then, if the user presses the Pump 2 key within the first phase of the Filter Cycle, Pump 2 will
turn off.
