Grand DC system LED problem

[Roger Wheelock]

Hi Brad,

Sorry to hear about the problem you had and that we failed to solve it on the first go round.  I'll copy Kelly Hollifield on this and Randy Kaufman who is also doing tech support these days.

We would certainly appreciate you returning the defective light panel so we can inspect it and improve our process here at the factory.

When we introduced the H5 humidistat we also introduced a package of replacement accessories that could be used for trouble shooting in the field.  Unfortunately, this hasn't been embraced by technicians or perhaps we haven't communicated clearly about its use.

We should have sent out the humidistat, light panel and low water sensor to ensure that you had what you needed.  We have done this in the past, and I will ask Kelly and Randy to do it in the future.

Here at Dampp-Chaser we appreciate the support of technicians and know what a hassle it is when something like this happens.  Again I apologize for the inconvenience and frustration you experienced.

Sincerely

Roger Wheelock, VP
Dampp-Chaser Corp.

  Hey Everyone, 
  Just installed a grand Dampp-Chaser (new style with the modular plug-ins) and had a weird problem. 

  The low water (amber) light would come on if you removed the wet pads from the smart heater bar 
  and
  The red pad light would come on when you pulled the water probes up out of the tank
  Exactly opposite from how it's supposed to work. 
   
  Called DC central command and they determined I need to replace the humidistat. 
  They sent it to me, I installed it, and same problem. 
  Then I went home and grabbed two additional grand dc systems, to try out their humidistats. 
  Both of them did it too.  

  Finally....started checking other things, and discovered that the problem was the LED panel.  
  Somehow it got wired wrong. 

  From now on I'm carrying two systems to an install, so I can avoid the repeat visits. 

  Anyone else run across this?
