UGH! My 2 week old DC8 not working.

HI I recently purchased 2 DC8 to use with me AC3 and tonight the lights were still on when they should have been off. The Led is on but does not blink. It is the second one daisy chained off the other so I plugged it in directly and get the same thing. Any ideas what I can do to fix it? This is really disappointing! Now I have to put back all the timers I had!

Please try the following:
- Power cycle the DC8.
- Plug the telephone cord from the AquaController to the first working DC8 into the non-working DC8.

The unblinking LED means that the controller is not receiving any commands. I've seen a couple of customers make there own telephone cords and not fully crimp the connectors, and damage the DC4 or DC8 RJ11 connector. The wires in the RJ11 connectors are bend slightly and don't make a reliable connection. Don't know if this applies in your case or not. Also note that the max recommended telephone cord length is 10 feet.

If none of this helps, please send an email to support@neptunesys.com, or call 408-578-3022 and we'll help you out.

I have a Jr with a DC8. I daisy chained my heaters but strangly it turned on one heater and the others remained off. Its affecting my system so I removed that heater. What's wrong. I have I bealive there is about 600 watts of heaters on my system. It was working as it should for a while
 
Bugger I would answer if I knew the answer. I am not sure what you mean buy daisy chained my heaters. some of the experts probably are not also.

Can you manually turn the heater on/off through the controller (control & status -> manual control)? I need some more info. Are you using multiple outlets for the heaters? What timer names and program statements for heaters? What do you mean by daisy chaining?

It act's strangly somedays it works others it dosen't. I only use it for lights and heaters but it dosen't turn on my MH I need to do it manually. My heaters get stuck on the on postion.
 
I just remembered that I have the lights set so that it turns off at temp point but why does it keep my heaters on?
 
Sorry for the delay in answering, but I thought you solved the problem. Please answer my questions: Are you using multiple outlets for the heaters? What timer names and program statements for heaters? What do you mean by daisy chaining? Is the icon for the heater in the on or off state?

I use one outlet for the heater A5, there are three heaters on that one outlet, "daisy chained"; Is that wrong? Should I have put each heather on its own plug.......

I did a sloppy job programming. I hope this is where the problem lyes.
LT1 * -A01
LT2 2* -A02
Het % -A08
* represents a lamp
# represents a triangle pointing up.
If Time >09:30 Then LT1* ON
If Time >21.30 The LT2* OFF
If Time>10:30 Then LT2 *ON
If time >19:30 Then LT2* OFF
If temp < 78.7 Then () () () () ON
If temp > 78.8 then () () () () OFF my controler is manualy shut off I guess
If Temp> 80.0 then LT2 OFF
OSC 100/010 ON Then HET # ON <(what the heck is this?)
OSC 010/010 On then () () () () OFF
If feed cycle then HET # OFF
IF feed cycle then () () () () OFF
IF PH > 8.35 then () )( () () ON
If PH < 8.35 Then )( )( )( )( OFF
If time > 00.00 Then ()( )( )( OFF
IF Ph > 8.50 then () )( () () ON
If PH < 0.800 Then () )( )( ) ON
If Temp < 75.0 Then () () () ON
IF temp> 78.0 Then () () )( ) ON
 
It is OK to have multiple devices plugged into one outlet. Just don't exceed the 6 Amp current limited on each DC8 outlet.

This statement:

OSC 100/010 ON Then HET # ON <(what the heck is this?)

will definitely cause problems; the heater is going to be on 100 minutes out of 110. Get rid of it.

What are all these () symbols? If they are black squares, then you deleted the timer name so that the program statement now no longer refers to any timer name. I recommend that you delete those statements, or edit them to call out the right timer name.

I think your program should be something like this:


If Time >09:30 Then LT1* ON
If Time >21.30 The LT2* OFF
If Time>10:30 Then LT2 *ON
If time >19:30 Then LT2* OFF
If temp < 78.5 Then HET ON
If temp > 78.8 then HET OFF

No, the calibration constants, and program are stored in nonvolatile memory and will remain unchaged after a power cycle.

Nevermind that nasty PM I sent you I seem to have worked it out. ( the plug was not in the DC8 properlly so it was my fault.)
You have to make it more stupid proof. and Userfriendly.
