Fan/chiller setting change question?

[tonym10]

I got the replacement controler that you sent me with the version software on it with the battery saver. But you have changed the fan/chiller setting now. On my old one I had the heat set to turn on at 80 and fan to come on at 81, that worked perfect. But now with the same settings my fan also comes on at 80 instead of 81. I read the note about how you changed the chiller setting by 2 degrees. But I cannot make sence of this. Am I correct in thinking that to have the same settings as before I must set my fan setting to 83 instead of 81. SO at 83 it will come on at 81? When will it turn off, at 80.9?
If this is all the change , why was it done?
Thanks

Ya this has gotten real confusing now. How I have mine set up is the heater is set to come on at 80 so it should turn off at 81. The fans are set up to turn on at 82 so that they will turn off at 80. The one degree gap should keep the fan/heater from fighting each other. You can test this out by putting the temp probe into a container with water and slowly add hot water until your fans come on and then put a small amount of ice into the container to bring down the temp until the fans turn of and the heater turns on.

Mine doesnt work like that really thow. My heater is set to turn on at 80, so whent he water drops to 79.9 it turns on, as soon as it hits 80 it turns off, thats ok with me. But I have to set the fan to turn on at 83, but the water temp is really 81 when it turns on not 83. That just doesnt make sence to me that we need to make up a fake 2 degrees in there. I have tested it , by accdent , when I noticed at 80 both my heater and fan were on. the fan didnt turn off till I changed it to turn on at 83, well it turned off when I had it at 82, but I wanted a 1 degree differnace.

Try bringing the fan turn on temp down to 82 and see what happens. I remember having a problem if I had the temps to far apart.

heres the problem that I'm having....my fan/chiller setting is set to turn on at 81 degrees....but instead of turning on at that set point, it turns on 2 dgrees before that, at 79 degrees!, at which point it then contiously turns itself on and off every second, so that the channel LED light is blinking on and off.. I thought the whole idea was to turn on the chiller at my pre-determined setpoint, and have the reef keeper auto turn my chiller off after it drops 2 degrees, correct?..but instead, the reef keeper is turning on my chiller 2 degrees before the set point....this is my second remote display...now, I'm starting to get a little impatient..please help!

[CCG]

You know I had that turning on and off every second problem to. I think there may be a problem if the set points for the heater and the chiller/fan are two far apart or to far of the preset, set point. I don’t know this for sure though. In my case I have them set 2 degrees apart (80 heater and 82 fan) and after doing this I haven’t had a problem sense. Both of you guys may want to e-mail DA and see what they say. Your rights though I would think that you should be able to set the temps at what ever temp you want and it should work. HTH

Trust me when this happened to me i was a little more than a little upset.

conecticut, thats exactly what mine did, I had it set to turn on at 81 , but it turns on at 79, my heater is set to turn off at 80 , so they both ran at the same time. SO I raised my cool temp to turn on at 83, 81 +2=83, but it just makes no sence that they did this change. SO now my fan comes on at 81 , does that make sence? Anyway it works ok, I am just confused at this programming.

[connecticut cichlids]

this is really upsetting me..I'm now sorry that I gave up my original remote with v1.1, which i had zero problems with....I'll try and raise the turn on temp to 82 to see what that does...I personally try to keep my tank ( 16g ) around 77.5 degrees, with my coolworks iceprobe chiller, and it has no problem doing that with the original remote.. If I have to raise the turn on temp of the chiller to 82 -83, im really gonna be ****ed..!

[tonym10]

Lucky for me I do not really need a fan/chiller, I just have a fan plugged into the cooling outlet just n case. My tank stays at 80, the heater is on frequently to keep it there.

Mine does the same thing guys, I was perplexed when I came home one day and the fan was on/off/on/off/on/off/on/off basically pulsing... Then I reset the unit and found out it would come on 2 degrees cooler than it was set, so it was fighting the heater for a while. Now I'm uneasy as to where I'm supposed to set it, because I don't want my water reaching the 83.5 degrees I now have my fans set at, in anticipation of the fans turning on 2 degrees sooner. What the heck? This is very frustrating.

I was more happy with my V1.1 unit in this respect, as it came on when I set it, and would shut off when it was supposed to. I got an E-mail from Nick asking why I haven't set my unit back thus far. I truthfully answered that I haven't made it to UPS yet, but now, I'm debating which one is less disfunctional. V1.1 or V1.4?

Not to mention that my menu buttons are all messed up....

An update on this subject!!!....this morning, I recieved an email from Nick, stating that they are aware of the problem with the 2 degree temp setting, and on-off problems with the fan/chiller settings. Nick told me that they have CORRECTED this problem..he also said " We have changed the way we implemented the fan/chiller setting (again). Since some people didn’t like the built-in 2 degree margin we changed it to be programmable (some want margin and some don’t). So you can now make it zero like the old version that you are used to, or any number in-between by dialing in a separate on and off temp. This new version also fixes the behavior that you are seeing as we had a slight problem when certain conditions were met. " It sounds like there is now a V1.5. Once again , I can't say enough about there customer service.. I will be expecting a replacement to arrive in the mail soon..You guyz should also email DA about a replacement remote with the latest version also, if you don't like the 2 dgree temp situation....:)

Ugghhhh... When does it end?

[tonym10]

Unbelievable

Here is the programing that I feel should be built into tis unit.
1. The heater should have aprox 1/4 a degree buffer zone built in, in otherwards, if I have the heater set to turn off at 80 , it should turn off at 80.25 but not turn back on till it drops below 80. This way it is not always clicking on and off
2. The fan/chiller the same thing , if I set the chiller/fan to turn on at 81 it should turn on at 81 , then turn off at 80.75., giving it a little room between temps, rathher then cycling on and off.

[SHOmuchFUN]

Well that's what was supposed to happen in the V1.4, but it wasn't programmed that way. I was told it was supposed to turn on at your set point and STAY on 2 degrees below it and THEN shut off... But mine is funky, it'll either work that way, or it'll cycle on/off 2 degrees below the set point. I'm miffed how it should work, or how it was programmed to work...

[connecticut cichlids]

your exactly right SHO...mine cycled on 2 degrees below the set point too, and then kept turning on and off ( pulsing ) like you mentioned above...so now I'm awaiting a 3rd replacement remote...:)

O.K. Guys,

Here's the scoop: We have changed the fan/chiller feature again to finally get to the best solution for all customers. We changed it the first time when people complained that it didn’t work well because it would cycle chillers too often. Then, of course, the other half of you didn’t like the new method. Version 1.4 didn’t accomplish everything we wanted to, it can still cause the channel to turn off and on too often. The reality is v1.4 will be fine for many, but there also will be those of you that will want the newer version since you use this feature intricately with your system.

So there is a version 1.5 that has programmable margin (hysteresis). You can program the on and off temperatures separately, making them whatever distance apart you want, in 0.1 degree increments. For those of you who are having problems we would be happy to trade it out. We have an exchange program that requires a deposit, but in return, we pay shipping both ways (like some of you have done). We started a deposit system because it is too costly for us not to get the originals back in a timely fashion, so we hope you understand. To coordinate a trade email: [email protected]

Please know that while these problems have been an inconvenience, we are working hard to make every ReefKeeper customer happy. Also note, on our web site, that our long-term price is $249 (starting Feb 14th). While many of you had to deal with some of these kinks, we hope that getting a good value ($219) has taken the edge off. We do appreciate all of your enthusiasm for the product, and really think the ReefKeeper is a winner, we are committed to proving that to you!

Can you do that programming (hysteresis) to the heater?

[SHOmuchFUN]

Thanks Nick...

E-mail sent and V1.1 is on its way back.

Should we assume that V1.5 is going to stay? Or are there updates forthcoming that may be worth waiting for? I'd really like to stick with one unit for a while, as I live in a remote area, getting to UPS is not entirely convenient.

We have no plans to change anything for awhile. We want the product to stabilize with the current set of features.

Got my replacement, much better. Thanks

Same here

Got mine yesterday... Hopefully it's working, but I'm at work, so who knows? But I did notice the on/off feature of the fan/chiller setting. It made me smile and say "Why wasn't it like this in the beginning?"

Hehehehe.

I just got my yesterday and missed out on all the fun completely :D. Thanks for the all the hard work and developement so I could get the final version. :)
