Up or Down until "Back" is blinking; then press the Select button). Now, choose the desired function for that channel

and press Select.

If you set the channel to control a light, select whether the light is a metal halide or other type of light. If it is a Metal

Halide, the ReefKeeper will ensure that it has time to cool down after a power loss before turning back on. After making

your selection, set the time that you would like the light to turn on. Use the Select button to make each selection for

hours and minutes. Then, set the time you would like to have the light turn off. Pressing Select will return you to the

main channel selection menu. Note that if the ReefKeeper has been power cycled within the last 15 minutes any metal

halide channel will be off until a full 15 minutes have passed. The LEDs are blinking during this time to indicate that

they will be turned on after the 15 minutes has passed.

If you set the channel to be a sump pump the ReefKeeper will automatically turn the sump pump off during feed mode.

If you set the channel to be a powerhead, choose which wavemaker cycle you would like the powerhead to be a part of.

For more information, see the

Setup Wavemaker

section below. After making your wavemaker cycle selection, specify

whether you want that particular pump to be on or off during night mode.

If you set the channel to be a heater, you will need to specify the temperature at which you would like to have the heater

be shut off. When using the heater function, set the thermostat on your heater to no more than two degrees above the

threshold temperature on the ReefKeeper. This will allow redundant protection from a single-point failure.

If you set the channel to be a fan/chiller, you will need to specify the temperatures at which you would like to have the

fan/chiller turn on and turn off. In this way, the fan/chiller function allows you to set your desired hysteresis. When the

water heats up to the turn-on temperature, the fan/chiller turns on. As the water then cools down, the fan/chiller will turn

off at the turn-off temperature. It will then not turn on until it reaches the upper turn-on temperature. This prevents the

fan/chiller from cycling rapidly when the water is hovering around the set point. You may, however set the turn-on and

turn-off temperatures to be equal if you would like the water temperature to maintain at a given temperature regardless of

the rate at which your fan or chiller cycles. When using the fan/chiller function, set the thermostat on your fan or chiller
