I didn't understand...

[zapoy]

When I check a new(for me:D )controller ,I saw two parameter.But I didn't that decide that dripperiod and drain down time are same meaning..We must give value for each parameter.
this controller is Next..

Hi Zapoy and welcome to the forum

Congratulations on your attempt at posting in English as I wouldn't know where to start to post in your mother tongue :p

Unfortunately, I think what you are trying to tell/ask us has been lost in translation, and that's why you are not getting any replies.

Is there any chance that you could try to explain it a little better?

I think that he has a controller which has, amongst others, two options...
1, Drip Period
2, Drain down time

He needs parameters for each one and also, I think, an explanation of the two items.

I would go for the 'drip period' as the time for the coil to complete defrost and drip water under gravity.

The drain down time is possibly to allow the drain pan to clear but I'm not sure myself.

Any takers?

I'm so sorry.you're right ..

I'll try to explain again...

I have a controller called Next .. At the controller ,there are two parameters that they're ' DripPeriod' and 'Drain down time'...I think they are same meaning.But I must give value each parameter?
I hope I could explain my problem

Drip time is used when the fan has been running whilst on defrost.(off-cycle)

Drain down is the time after defrost you want to wait before you start up the compressor.(electric or hot-gas)

If you are using assisted defrost i.e heater or hot-gas then you do not need drip time and set it to 0.

If you have the defrost as off-cycle and the fan is running,the drip time is the time the fan is off after defrost and this is set to 2 minutes.

I hope that made sense.

I'm not familiar with the controller but if it has controlled timer outputs for drip time and drain down then I'm assuming these occur after the defrost heating period is completed.

It would be helpful if a link can be found for the operating instructions for this controller and posted here. My guess is these settings are related to your post on another thread.

No, not my controller,just going by the posts above.

I cannot find any info on the "next" controller that Zapoy is working with.Looking through data sheets on some controllers i work with,i found drip time settings or drain down settings,but not both on the same controller.

I spoke to someone regarding these settings and was told that depending on the type of defrost used,drip time settings can be disabled and just drain down can be used,or visa versa.

That may be chunk, but is the definition of those settings you received the same as what the factory intended them to be. Stranger things have happened.;)

As you say,it would be nice to get the proper controller info instead of me guessing:p.

[Brian_UK]

I've found a "nextcontrols.com" but their website doesn't have any tech info on it.

It looks as though they might sell you some however...

[zapoy]

I want to send documents but I don't know what I can?
