Description
The Gecko Heater-Controller is the heart of the Water Quality System across the Endless Pools product line. The Gecko
carries the programming needed for all product configurations. The replacement controller’s programming (low-level) MUST
be configured once power is introduced to the system.
Replacing & Programming Gecko Heater-Controller:
Refer to the following instructions for replacing and programming the Gecko Heater-Controller. The controller MUST be
programmed for the appropriate configuration to function. Refer to the chart on the following page for the correct low-level
configuration for the product purchased.
1. Isolate the existing heater-controller by closing ball valves and/or plugging the water quality system thru-wall
penetrations. Remove the heater-controller from the Water Quality System plumbing.
2. Install the replacement Gecko and re-introduce water by opening ball valves and/or unplugging thru-wall penetrations.
Inspect all union connections to ensure there are no leaks.
3. Re-supply power to the Water Quality System. The heater-controller will go through a boot-up cycle which can take
up to 5 minutes. Once the keypad is displaying LL and a blinking 2, the low-level configuration can be
programmed.

to store the programming configuration. If the light button is not pressed within 25 seconds, then the
