FUNCTIONS
Functions
Sensor Type
The controller accepts two flow signal types. Either flow switch (on/off) or flow sensor (proportional).
The proportional rate can be set to 600, 1000, 2200 pulses per litre.
Fault Detect
The controller can sense if there is a fault and signal the shower to shut off, preventing flooding (only
available when used with AKW compatible shower).
Calibration
Run the shower at the expected normal flow rate. The pump must run at a speed which removes the same
amount of water as is flowing in.
Adjust the calibration value so the water level stays approximately the same. If the water level drops,
decrease the value on the display so the pump runs slower. If the water level rises, increase the value on
the display so the pump runs faster.
Auxiliary Switch Type
The controller accepts two switch types - latching or momentary. This function manually starts/stops
the pump. The pump will stop automatically after 30 minutes, if not stopped manually. Switch available
separately - AKW Stock Code: 25488 (Latching Switch)
Start Delay
The time before the pump starts after the shower starts. This is to allow the pipe work to prime with water.
Run on time
The time the pump will run after the shower has stopped. This is to ensure complete clearing of water
from the shower tray.
