iTemp Temperature Probe
The ReefKeeper Lite System has the unique ability to monitor temperature from a probe con-
nected directly to the system bus. The probe consists of a standard temperature probe with an
RJ bus connection on one end. This allows the probe to be connected at the end of the bus chain
and lets the RKL system monitor temperature without the usage of an SL1. Besides the physi-
cal connection of the iTemp probe, iTemp is treated exactly the same as any other input on the
system.

Chapter 2: Installation
Wiring Your System
The ReefKeeper Lite (RKL) is a modular system. All modules are connected together via the bus
cables included with the system. There is not a specic order when connecting modules to the
system, nor is there a required port order. Below are connection examples for each one of the
RKL system packages. These examples are intended to show a possible connection scheme for
your system.

General Mounting
It is important that electronic equipment never be mounted on the ground or the bottom of a
cabinet. All Digital Aquatics modules should be mounted as high as conditions will allow. Also,
all bus cables, probe wires, and power cords should use proper drip loops.
Correct Installation w/ Drip Loop Incorrect Installation w/o Drop Loop
Water damage is not covered by product warranties and is the leading cause of device failure. It
is the responsibility of the user to insure safe installation practices are followed.
Mounting the RKL Head unit
Mount the head unit in a location where it can be easily accessed for daily operation. While the
face of the head unit is splash resistant, proper ventilation is important.
ReefKeeper Lite User Guide 5
Getting Started
Mounting the PC4
Mount the PC4 in a well ventilated location. Also, make sure it can be accessed in the event main-
tenance must be done, such as a rmware upgrade.
PC4s should never be mounted on the oor or any other surface where water can pool.
Mounting the SL1 (Included with the RKL PLUS and RKL NET package)
Mount the SL1 in a well ventilated location; close enough to the tank or sump so that all probe
wires can reach their mounting locations. Also, make sure it can be accessed in the event mainte-
nance must be done, such as a rmware upgrade.
Mounting the NET (Included with the RKL NET package)
Mount the NET in a well ventilated location. Please be aware that the module must be within
wiring distance of a network connection. Also, make sure it can be accessed in the event mainte-
nance must be done, such as a rmware upgrade.
Bus Cable Routing
It is important to make sure bus cables are routed in a way that will keep them safe. Make sure
they cannot get pinched or crimped. Damaging a bus cable can cause system wide failure.
It is also important to keep bus cables clear of lighting ballasts and wiring. Bus cables can pick up
electronic noise and in extreme cases this noise can cause interference to the system.

Chapter 3: General Interface
Getting Around
The ReefKeeper system and head unit have been designed to be as intuitive and easy to use as
possible. Navigation through the head unit can be accomplished by using the [UP] and [DOWN]
arrow keys. The [UP] key is indicated by a triangle pointing upward and the [DOWN] key is
indicated by a triangle pointing downward. Menus can be entered and exited using the [ENTER]
and [BACK] keys receptively.
Home Screen
The home screen gives you quick and easy access to the most important information in your
system.
Example Home Screen
Date and Time
The Date and Time are displayed in the top half of the display. The date is formatted as the cur-
rent day of week followed the current day of the month. The time is formatted based on a 12
hour clock using the A (AM) and P (PM) designators.
Please see page 12 on how to change the current date and time.
Quick Data
Quick Data can display any port (input/output) attached to the system. This allows for quick ac-
cess to all of your systems parameters without having to navigate through the menus.
A port that has been removed from the system will show up as “error”
The quick data will always say “None” when powered up as it does not store the sensor
that it was previously set to.
To change quick data
Press the [Up] button to go up through the port list.
Press the [Down] button to go down through the port list.

The ReefKeeper Lite (2.00+) uses the new ReadyFit functions. These are intended to simplify
setting up a system for some of the more common functions. All functions have been updated
to use the new EasyFlow menu structure where the ReefKeeper Lite will walk you though the
conguration options for each function.

On/O
The On/O function has a default state of “O”. It can only be aected by alarms, standby and it’s
mode. This is the most basic function and allows a channel to be always ON or always OFF but
still give the option to be controlled by alarms and standby.
To set up the On/O function
1From a Module’s Port Menu, select “Function” and press [Enter].
2Press the [Up] or [Down] buttons to scroll to “On/O” and press [Enter]
The rst setting is “Action”. The action determines the constant state of the channel. For
example, if you want the device to constantly be ON, set the action to “On”.
3Press the [Up] or [Down] buttons to choose between the “On” and “O” options.
The next prompt will be for “In Standby” with the options of On/O/Ignore. This sets the
state of the output when you enter Standby mode on the head unit.
4Press the [Up] or [Down] buttons to make your selection and press [Enter] to conrm.
The next prompt is for setting the default state for the output. If the programmed module
can no longer communicate with the head unit, the module will set the output to the state
chosen in the default setting. For example, if a heater is plugged into channel 1 on a PC4
and it can no longer communicate with the head unit, the default state will take aect.

Controller
This is the most dynamic control function for the ReefKeeper Lite. The controller function is used
to take an input such as temperature, pH, ORP, salinity and more to cause an output or channel to
change it’s state. Such as if the pH rises or falls you can turn on or o a reactor pump as needed
to stabilize that value. The Controller function also allows for more control over a heater or chiller
allowing the user to set the hysteresis. These advanced setting are pre-set in the Heater, Fan and
Chiller ReadyFit functions.
