hello

I have problem with my ac chiller with my hardware board Same as photo my controller is W3000 controller..

my problem is i have alarm code 211 and 212 is high pressure in circuit 1 and 2,every things in my unit is ok and i check my high pressure is ok and change it by new but still alarm is appear and i connot run compressor.

we I try to change compete hardware board by new no alarm coming because is new board.SO COULD any one help my to to delete this alarm i have now 10 PCB board with same alarm..!!

i have user psassoword is 1234

No reset switch in pressure switch.. Im sure i dont have any problem in pressure switch

Have you a photo of hp switches

Try the following.
10 ALARMSPress the ALARM key once to enter the “alarms menu” and view the alarm message along with its code.If there is more than one alarm, scroll the menu using the “Up” and “Down” keys.To reset the alarm, press the ALARM key again and HOLD IT DOWN until “No alarm active” is displayed.If the message does not appear it means that one or more alarm conditions are still active.Press any other key to exit from this menu.

When i tried to press alarm key for 3 second the alarm of high pressure is disappeared but is coming agine after few second.

Every time i have same alarm I just change the complete PCB hardware and every things working good thats means I dont have any problem in my pressure switch.

Around 5 years Im changing around 10 PCB when i have same alarm because i dont have another choose..

Even When I tried to make pay pass for high pressure switch by installed wire jumber but still the alarm appeared..

Is there a second high pressure switch on the circuit that you are missing? Is the motor thermistor in series with this alarm or any other switch?

Like al said you could have a hp transducer and a Manual reset hp switch it’s not uncommon on some makes of chillers

Are the pressure transducers 2 wire or 3 wire?

Press the black button in the middle of the switch that’s the reset

2 wire only .. I tried to make wire jumber to paypass but still same alarm ..

As I say before I dont want to change complete board it is so expensive

I tried and no things happen

After pressing the black button you must do what Grizzly said

Do you have continuity through the 2 wires from the sensor?

Disconnect it from the pcb and measure for continuity with a multimeter - even when pressing the reset button.

Yes I have continuity between 2 wire ( 0.6 ohm) thats means is Normal close

All HP switch has been changed by new but still same alarm . I tried today to change complete board PCB and alram is going .. thats mean I dont have any problem in my unit only in PCB and now I have 11 PCB with same alarm .

I think there is some software problem may be

If you link out the HP switch does your chiller run?

Have you got a photo of the wiring diagram

Here is the manual, there is a description of the board and connections. Also check the factory settings - at what pressures HP is etc.

Maybe it will help.

What is the Alarm Number on the display?

Look at his first post, AL:211 circuit 1

Did any body know how to connect my Pc to this PCB
Which software can I use ?? Attachment 15507

Any update ����

If you have continuity whole time on control circuit related to that alarm, you should take that board to electronic repair shop and tell them to check digital inlet which is related to that alarm. Probably optocoupler issue!

If there is no problem with related digital inlet than it is software issue and you should contact dealer of these units!

Are you saying that you have 11 separate chillers with same alarm?

Had a similar problem turned out to be the battery module which feeds the alarm relays if memory serves me right. Caused by low battery voltage but for some reason gives up hp fault.

But you probably dont have acess to change programing off these PCO-s since Climavenata is making its own software for PCO and it is protected.

Your best bet is to contact manufacturer.

By my expirience, they will never admit that their software is faulty and you will be bounced around like some stupid monkey folowing their instructions. But, maybe you will be lucky monkey!

I usualy install μchiller2 SE in that case, if it is possible.

Are you sure that High pressure alarm comes from HP switch but not HP sensor?
