What do I need to configure this new board, hand held or laptop with the adapter, cable and free software download?? If I could get tech support to pick up their phone before an hour has passed on...
Yes definitely exercised the google route, but with no success. Thank you for the assistance
Got it thank you, is there a separate technical guide for the Modbus communications for an existing 3rd party automation system?
Here is the control board picture
York branded RTU model#T33 PDF's
If anyone has any manuals IOM and any info on control board config, replacing new board but of course didn't come with any manuals for install. I am pretty sure I need the hand held to do the setup...
:eek2:
I know how the purge works, regardless of vintage and the outcome of incorrect operation (Bypassing), not trying to get in a ****ing contest here, I am basically stating how I operate the purge. The...
I agree with you and Healey on the newer machines with the regen cycle I have not had any run ins on the newer machines but them again I can't say I have allowed any of my customers to run the purge...
What I think happens is XYZ do it cheap maintenance services machine, slaps a bypass on it flips it to ON and good to go for a few years, sometimes they come back pull the hose and sometimes not but...
Just in the last year I have added over 1700lbs R123, and 380lbs R11 on non leaking machines that were left in the ON mode year around on just 4 machines. You can leave it in whatever mode you want...
It would be nice as Healey said if the OP would respond with some more clarification but it's looking like another single post bandit probably last time we will hear from them. And not to drag this...
Depends, how you define NORMAL, technically the purge compressor should not be running long enough to freeze up, usually means the purge can't keep up with the leaks on the chiller, does it happen on...
saturated evap/cond temp sensors but they need to be verified as well
Ok well that's only 23.44 deg not 50 plus deg, and technically that should be actual measured liquid line/dropleg temp not condenser pressure converted to temp. Did you measure temp or just convert...
How did you calculate your condenser approach or did you get it off of display panel?
Ice build up is different than frost build up. Which is it? Ice is solid like ice cubes and frost is like snow but thicker and can easily been rinsed off with water or heat gun. Ice on the other hand...
Yes on fan cycling based on pressure since you are low low ambient conditions and head master only dumps to receiver if need be. So so far it was just overcharged with a ref leak on CPR?
The hot gas line for defrost is piped direct to the distributer on evap correct? if so all is good. If it is piped to the txv then it is incorrect. You should have 3 lines going to the indoor unit...
Hot gas defrost/discharge pressure feeding evap for defrost downstream (after) of metering device
Yes please keep us updated.
Doesn't matter how you hook your hoses up differential is what your measuring, it's not possible for the outlet to be higher than the inlet unless the CPR was installed backwards and it's not.
CPR inlet pressure is 407 outlet is 50.
That's how I read the pic as well, you can see where the hoses are hooked up and the gauges are reading it as well across the CPR unless I'm missing something here.
In this application with the info provided including the pic of the gauges across the CPR is 350 Differential. When the unit goes into hot gas defrost it dumps discharge pressure into the suction...
350 PD on that crankcase press reg valve is probably the max rated differential, its doing everything it can and probably ok, your gauges read R404 and you said it was a walk-In freezer but no...
Whatever happen on this one?
Yep got a new screw on cap and bracket, trane did still have that, I just liked the upgraded sump and cover better, Im also gonna move the eductors to the old sump, add a refrigerant cooled oil...
No performing a conversion and would have like to put the oil sump with the sump cover that has the screw on filter and oil sampling port, but since Trane no longer makes the sump its getting an...
Got one in the toybox, still in its original packaging, got one in the truck too, somewhere!!:whistle:
Not near as long as it would take to gather the endless amounts of data you are talking about and attempt to be accurate on a per application basis, there are already data histories being gathered...
If the MODE (Heat or Cool) is true, start a timer. If the space temp is greater than or equal to the space temp plus 1 Deg F, stop the timer and then you know how long it took to raise the space temp...
1. No you must use IPLV, call the factory for this number if not in literature they can tell you.
2. Design WB of tower not actual
3. Design KW at nominal full load not actual, If 2 identical...
Reminds me of a rebuild we did a couple summers ago, fairly new apprentice, I had to run and get a box of rags, BIG cup of coffee, and some cleaner. Before I left I repeated myself at least 3 times,...
That works. Thank you
Trying to find a new or used Trane CVHE/CVHF Oil Tank (Sump) with the integrated oil filter style (Cover) Factory says obsolete. NOT the latest style with refrigerant pump and sets on the ground but...
Holy Moly!!!!!!!!!:eek2: Lol cant say I have tried that teardown method before, good thing its trash cause if it wasn't it definitely would be now.
What Healey is explaining which is correct (And service engineers that generally work on CH530 should already know) There is nothing wrong with the chiller as presented by the OP. 1. the BAS has it...
1. Remove the inlet sensor and replace it with one of the other chillers inlet sensors to see if the alarm code goes away. 2. If alarm still there after replacing with good sensor, then run a new...
Ditto on the water potential could be Thrust bearing noise!!!!:whistle:
Post a log and serial If you want design delta P as previously mentioned and try to get your post count up!!
Yep doubt were gonna get a log. LMAO
A Log sure would be helpful!!!
In my experiences, subcooling and superheat are a great tool for determining "approximate" charge but by weight is better. Not saying its what I do every time on every machine, but very often after...
If its an emergency or If Im familiar (verified charge) with this machine I would transfer and recover remaining, otherwise Im pulling the charge and weighing it in to kill two birds with one stone,...
Post a Log before and after you clean the condenser coils. And I don't mean hit it with a water hose to knock the surface dirt off, deep clean it.
LOL:eek2:
I could be wrong on the flow switch physical input in auto stop mode But I was pretty sure that if the chiller was in a auto stopped condition but there was flow proven it would start the pump not...
Its always a timing issue regardless of situation, If Trane says run the pump now you have X time to move water at an acceptable rate or else fail will happen. Same when Trane says stop pump you have...
If you jump in to the tower sump (highly recommend scuba) sink to bottom and with both feet flat, lean at a 45 so you can get the angular position of yourself as long as someone is measuring the...
