Sir, i have a question pls help. Our chiller model is YCAA-B 170. With 4compressor (2 refri. circuit) We find that chiller running only 2compressor always and show 2 of 2steps, I have also check and confirm other 2compressor still no problems. Have any setting parameter about compressor no. or steps? But i cannot find these 2 parameter even in services mode Thank you so much

[@latentfusion2563]

go to options press enter and check that system switch one and two are both set to on. push the arrow buttons up or down until on is next sys 1 switch + sys 2 switch. also scroll through options until you come to local/remote mode. switch it to local mode and observe operation. scroll down to lead/lag control in options and set it to auto. press the program button then enter, then scroll through until you get to total number of compressors. make sure that it is set to 4. same goes for the total number of condenser fan motors. good luck and let me know how you get on.

Excuse me my problem is one a fail the text in display "interventions the fluid about to"

[@latentfusion2563]

Sorry my friend I don't understand the question. try putting what you want to say on a word document and then translate it to English through the Google translate. worth a go!

Sir I have one question System # 1 and System # 2 not showing parameters in display like suction temp; Sat suct. Temp; superheat; EEV all this are not showing in display of both system what is the problem can u help me chiller working but not showing parameters... all sensor are connected if any program setting can help......

[@latentfusion2563]

I will assume you are working on a older YLAA chiller. on some of the older YLAA'S that operate expansion valves instead of EEV'S they do not display suction temp or superheat in the system info. you will only be able to see the suction pressure and discharge pressure all other values must be measure by you. hope this helps

[@ashpaktechnicalsupport]

York Model # YCAL 0347 Before it was showing all this parameters but suddenly it is something wrong after that not showing all temp. Parameters.....

[@latentfusion2563]

check in the options menu under expansion valve that EEV is selected and not thermostatic. to change you may have to enter the service program mode. service switch in the off position, program button, up up down down enter. scroll through parameters until you come to expansion valve selection. have a go.

@@latentfusion2563 Thanks Sir ..I will try and reply....

[@ashpaktechnicalsupport]

@@latentfusion2563 Thanks a lot .... Sir... It's done now... All temperature parameters showing same like before.... Thanks again Sir... It's really help for me...!! Have a good Sir....

Hallo Sir... There is one CARRIER Chiller Model # 30XA 0402 A 6 There is Alarm Comes all together Like Circuit A Oil pressure transducer Circuit A Economizer Transducer Circuit A Loss of Communications with Fan Board A Circuit A Loss of Communications with EXV Circuit A Loss of Communications with Compressor A Which alarm is comes for Circuit A same that Alarm comes for Circuit B also .... Any setting or something else... Can i expects Any help from you ....

[@latentfusion2563]

If you take a look at the common fault it appears to be a communication issue with the main board. It could be a break in the interconnecting wiring to the inputs or a faulty control board. Have a closer look and bell out the existing control connection. I suspect an issue with the board. good luck with it.

[@latentfusion2563]

also check the control board power supply. ensure that there are no blown fuses.👍

[@ashpaktechnicalsupport]

@@latentfusion2563 All Transformer have fuse and all checked, its ok, both compressor Board getting input 24 vac but it should be output 24 vac for Oil heater relay it's not getting at the relay ( Contactor )... And i couldn't found main board output I am confused because there are 1 main board 2 compressor Board to find which is the problem.... If any good easy way to find .....?

[@latentfusion2563]

I believe the fault will be with the 'a' compressor circuit board or communication wiring. This fault will also prevent the circuit 'b' from operating. If another carrier chiller is around you could try borrowing parts from it. at any rate you will need to order in some parts. let me know how you get on.
