Digital Aquatics ReefKeeper 2 Controller Information



pH Monitoring and Control
The ReefKeeper’s pH feature allows the user to monitor pH to 0.01 resolution. A channel can be linked to the pH measurement to control devices that raise and lower pH. Common pH probes are supported and an easy calibration will ensure an accurate reading. We recommend using Pinpoint pH probe (Neptune pH probes not compatible).

Upgradeable Firmware with Free PC Cable Adapter
Customers will be able to update their unit when new software features are released. The serial cable adapter is included with the RK2 system and the firmware update program will be available for free download whenever new software is released. To perform an update you simply press the "Go" button on the firmware update program. Then the program auto-detects the serial port and performs the upload, it`s that easy!

BLUE Backlight LCD & LEDs w/ dimming The ReefKeeper 2 now comes with an even sleeker design employing a blue backlit LCD, blue status LEDs and a black overlay background all standard. Users can set the brightness to 25%, 50%, 75% & 100% as desired.

Manual Override
Each channel has a manual override to allow for quickly turning on/off channels when working with your tank or if you just need to activate your lights for an unexpected visitor.

Digital Light Timer
A light timer can programmed with an on and off time in 15 minute increments. Some or all of the channels can be programmed to be a timer. New! – Lights can now be programmed to turn off when the temperature exceeds a set value.

Night Mode - Independently Programmable
Night mode can be configured independent of your light configuration so that moonlights can be configured to be on at night. You can also disable night mode altogether if desired.

General Purpose Timers
General purpose timers allow for a single channel to turn on/off multiple times in a day, or provide an oscillate feature for things like top-off, etc. that you might want to turn on every so often throughout the day (independent of wavemaking).

Wavemaker (with softstart)
There are 3 wavemaker cycles in the ReefKeeper, cycles A, B and C. When a channel is designated as a powerhead a cycle must be chosen for that channel. Cycles A/B alternate opposite each other, while cycle C alternates on and off independently. Under the wavemaker setup you choose how long you want each cycle time to be by dialing an A/B cycle time and a C cycle time. In normal operation an ‘A’, ‘B’ and/or ‘C’ is displayed on the LCD to indicate which cycle is on. During night mode the cycle times double creating a calmer environment. You can also program individual channels to be off during night mode if desired.

Softstart
Softstart is a much debated issue in the aquarium community; many argue about whether or not it even exists. The reality is that both camps are right in some way. Softstart does exist, however, it isn’t practical or cost- effective to implement perfectly. Digital Aquatics does implement “softer-start” for all channels. This is done to reduce the “clanking” of the impeller when a powerhead is turned on. Put Digital Aquatics to the test! The way to judge a product’s softstart capability is to listen to the pump when it turns on; there is always some clanking, but the goal is to reduce it as much as possible. Digital Aquatics tested many other products and has implemented what it feels is the best performing softstart available. Also, powerhead design is improving over time and pumps like the MaxiJet brand last much longer than some others.

Standby/Feed mode
Standby mode can be programmed to be from 1 to 99 minutes long. When the “Standby” (top) button is pressed the ReefKeeper turns off the powerheads and sump pumps that are programmed to be off during standby mode for the set time or until “Standby” is pressed again. Standby/Feed mode helps reduce the bio load on the tank by maximizing the food eaten by fish and corrals and minimizing waste. Food will not get whisked away into the sump filter and to dead spots in your tank. Standby mode is also useful when it is time to perform maintenance on your tank and you need all the water pumps to be temporarily turned off.

Digital thermometer & dual-stage temp control (temp probe included) The ReefKeepers digital thermometer is a reliable temperature sensor that is digitally filtered to provide accurate readings. Using the temperature measured the ReefKeeper controls one or more heaters and fan/chillers. The thermometer can be calibrated by the user so that near perfect (0.1 degree resolution) accuracy can be achieved from year to year.

Fan/Chiller control The ReefKeeper turns on chillers and/or fans when the temperature in the tank exceeds a limit. Most aquarists don’t want to listen to their hood fans when then don’t need to. The ReefKeeper allows the fans to be off unless they are needed to keep the water temperature down. This way you only have your fans on when you absolutely need them. A temperature limit can be chosen for the fan/chiller in 0.1 degree increments.

Metal halide “sure-on” Metal halides lights are notorious for not turning back on after a power interruption. This is because they cannot be lit when they are still hot. The ReefKeeper’s Sure-On feature detects power interruptions and allows a metal halide bulb to cool before turning back on. Since the ReefKeeper has an internal battery it will always be able to keep time and settings despite power interruptions of any length. If a metal halide channel is being held off by Sure-on after a power interruption, the LED associated to that channel will blink until the metal halide channel is turned on again.

8 programmable channels (No need for separate X-10 devices)
The 8 controlled outlets are built into the ReefKeeper making it easy to install and setup. No separate X-10 devices are needed to be purchased and setup, which saves aquarists time, space and money. The power controller is very compact for an 8 channel controller and mounting is very easy.

New! - 2 of the 8 channels (Ch 4 & 8) are traditional relays best used for light ballasts. Some ballasts do not light reliably with triacs (switches used in most controller products). This provides users with maximum flexibilty

New! - Channels 1 & 5 are offset to provide space that supports wall power adapters that sometimes come with fans. This avoids the need to run extra extension cords around your system which keeps you wiring clean.

Easier Fuse accessibility The 15A fuse is now accessible without taking off the cover off the device. It is also a standard easy to find size ? x 1 ? inch.

Resistive or inductive loads The ReefKeeper can control resistive (heaters) or inductive (pumps and ballasts) loads and still supply 6A of power.

Microprocessor design The ReefKeeper has an embedded microprocessor to enable advanced features like softstart, night mode, “Sure-On” and temperature functions on different types of channels, plus much more. It drives the LCD menu system for easy setup. It also reads water temperature, digitally filtering it to provide stable and accurate readings.

Display box can mount flush to cabinet for professional look
The display unit has two mounting options to accommodate different configurations. It can be mounted flush to your hood/cabinet for a sleek look by cutting out a rectangle. It can also be mounted easily to any flat surface. The outlet box mounts to a flat surface.

High power design: 15A total power, 6A per channel
A maximum of 15A can be supplied by the ReefKeeper, and each of the 8 channels can supply 6A (as long as the total current is less than 15A). A heavy duty power cord and a fused supply provides the safety that is needed for home use.

User optically isolated from AC power
The power switches use optically isolated controllers to provide the highes

Excellent!

Comments: Like most people I was at first intimidated by the thought of a controller. You can''t go wrong with this one,very simple to set-up and versatile enough for all but the most demanding reefer. No fancy programing language just straight and simple plug and play.

RK2 Two Thumbs Up Product Review by DAN F (Posted on 11/18/08)
Rating
Excellent!

Comments: As usual service was great, I had my RK2 quickly and intact. The RK2 is an excellent product, from both the functional and usability stand points. I had it up and running (controlling actually) in no time. It is easy to program via its menu system while providing flexibility in control options. The only negative is that the user guide is only on mini CD which my Mac doesn't support. However, this is easily overcome by downloading it from the manufacturers website. I wish I had my RK2 when I set this tank up a year and a half ago.

Excellent Controller Product Review by GREGORY PIZZUTO (Posted on 8/9/08)

Excellent!

Comments: I purchased an RK2 a few years ago and it has worked flawlessly with controlling various devices on my system. I just recently purchased the second unit to dedicate it to a lighting system for simulating sunrise to sunset in addition to moonlighting, in addition to freeing up outputs on the first unit to control other devices. For the money, this system can not be beat. Waiting to see some positive feedback on their newest system, the Elite, before making its purchase.

Outstanding! Product Review by ALTAHOE (Posted on 7/1/08)

Excellent!

Comments: This is, by far the most "bang for your buck" optional item I have ever purchased for my reef tank. Outstanding!
