Thanks Christo

Keep them coming

could i get the dimensions for the display and buttons below it for a case im designing? i would really like one but i need to design the case accordingly.

[gsmaster]

I attach the front panel dimensions for the controller.
The latest blue lcds have a slightly smaller bezel. These are the dimensions for this lcd to fit OK


Best regards
John

I used the old cut out patter for the new controllers and it works fine. I need to put a taper on my mounting screw holes

[gsmaster]

Looks gooooOOOOOOoooood...!!!!!

With the word "taper" you mean to widen the holes near the head of the screw in order to be lower inside the metal of the case? (I cant express it well on english...) So the screw head will be at the level of the front panel. It will look very nice to the look and touch

So the case's lcd "window" is 14mm height? Remove the protective memvrane off the lcd from one side to see if the metal bezel of the lcd is visible.

Yes you understand what I mean by taper. Taper means to start big and go smaller.
I don't have the cases ATM. They are getting power coated. Next Wednesday I can do what you request and check the bezel.

To taper a hole the way you are describing is called to "Countersink"
Nice job runmc.

Will it cause any problems for the controller parts and adaptor to be all together?

[jinu117]

Kind of funny... I think I've seen most people using taper for metal while countersink for wood. Same thing really :P
Looking good Ron

[Unseen]

nope You wont have a problem ron.

Freeze Pack Control goes together very well. I have another case to assemble, so I'll do an informal installation guide. I like this controller. I would love to see K-type probe though because it would be much better for connecting probe to evaporator.

I decided to mount the main controller board on the back wall of the case to avoid running long PSU and compressor wire from front to back of case. Thank you John (gsmaster) for the suggestion. I haven't securely fastened the stands to the case. I'm waiting on some super strong 3M tape to hold it with.

Hi Unseen or Gsmaster...

1 of my controllers the 1 on my Vapo System temp probe errors today ..
turned on vapo and it started my Pc strait away wich was Q6600 with 1.7vcore lol sensor says -111c

i know how to fix with re calibration and all that stuff..ice water in a bag

just wandering was it condensation on the sensor wich makes it give this error??

If so what would be the best way you think to attach on the end of the suction line ..i just taped it on..with black electrical tape..

Vapo standerd has heatshrink over sensor but this would be impossible now as its complete.

ideas on a good seal of the sensor would be appreciated.

Cheers Hori

[gsmaster]

This temperature could possibly be a bad connection of the sensor cable to the board, as well as a possible condesation on the sensor's leads.

The sensor's leads are in heatshrink, then dipped into hot glue, and then again heatshrink. The only possible place that candesation can cause a problem is bettween the sensor's case and the hot glue. You can warm the hot glue with a lighter in order to seal again any cracks.

I did not use heat shrink on the sensor's surface because that would make it slower to respond to temperature changes, and bigger to the size.

Also there is no need to recalibrate the sensor, This is not a calibration error.

Cheers
John

[HoriWanderFuLL]

o dear ..i did recalibration last night in ice water ..when it was 0c i reset..

last night it would not read colder than -2c after i done this

Today i just got home turned on the unit and it was reading -2c no differance when sensor probably should of been reading +21c maybe high as +24c...
as it usually would...

i will look at controller end of the sensor tonight ..

Maybe i should buy a few sensors of you since i have a couple of units ..and i doubt i would be able to buy here in Australia..since there 3 pins on the controller...

Cheers Hori

[jinu117]

Isn't it variation of LM335?
These sensors are widely used across globe.

[HoriWanderFuLL]

im not sure Jinu i actually havnt a clue ..im a Phase user not a Phase builder

[gsmaster]

The sensor is LM35 from National Semiconductor.

one thing I would like to have is automatic on/off backlight since it's pretty anoying with light on when unit is off (especially for those who have computer in bedroom).

I've fix this by putting a relay for diod parallel with compressor relay, not optimal if something fails but it's still possible to read the display (as long as it's not dark in room). I need to measure more but I hope it's possible to find another source of power to make lighing on when something is written on display.. shouldn't be diffict to make.

I'm also intergrating pwm controller for fans. will show you guys when controller is 100% finished, I'm still playing with it.

I'd love to have a 110/220v -> 12v PSU built into the controller ala VapoChill's Chill Control. Would make assembly easier as it'd eliminate an entire PCB from the build. Just a suggestion, a minor inconvenience for a superb controller.

[tim-]

gomeler:
yes thats easy to do BUT it will costa furtune to ship the controllers, the transformer will weight ~750grams extra for EACH controller, I don't want to pay extra for that. also it's nice to be able to choose transformer depending on use. For example if I use 230v fans it's enought with 3va transformer to run the controller and if running 2*deltas inside I need alot more, ~25va transformer.. it's good to have options.

More Freeze Pack Control

[TopherTony]

how well would this work on a water chiller? How about a water chiller and a SS in the same case? could it control both?

[gosmeyer]

They look very nice Ron.

[HoriWanderFuLL]

Runmc what enclouser is that custom make ?? looks good nice solid blocks stopping evap head flopping around...
