Started a RTAC last month and it came with a CH530 enclosure, about time.

The loss of charge diagnostic is generated when the ratio of EXV % Flow Command/Superheat Control Compressor Flow Estimate is 1.7 or greater.

The ratio should be 1 to 1. Everyone I've come across...

You didn't power the EXV before installing it in the body? Only once have I heard of the body needing to be replaced (employee of the evil Empire for 6 years).

I replied to the original post.
In your case go into binding view, click on the LLID that is not bound. Click bind. Go to the panel mount LLID for high pressure, believe it is 1U22. If you put a...

Go into View, Configuration, MP Config. Down to Bacnet BCI-C interface. Change to installed. Then hit load configuration.
After the Dynaview reboots. Go to View, Binding view. The BCI-clC should...

What exactly are you trying to do? The machine should have come with the LLID you are trying to install. Can only have one. Are you replacing a failed LLID? Every optional LLID that can be installed...

First go into configuration and enable the device you trying to add.Then after the Dynaview reboots you should be able to bind it.

Sent it to your email. To big to post here.

If mineral oil is greater than 1% the Trane recommendation would be to pull the charge, fill the shells with liquid R-22 to flush the oil and wax (which would be present as well) out.Then remove the...

My bad. Had to look up serial #'s on the oldest CVHE's I have. Both are 90's. Both had vent lines up sized and solenoids added.

Here is an old service bulletin for this machine. Vent should have been up-sized to 1 1/8". Oil tank needs to be the lowest pressure point of this machine or the oil will be in all the wrong places....

Found a spider nest in a Trane orifice once. Better than that, back in the residential days had a bat fly down a stack, through a furnace, and short the electrodes on an oil burner.Back to the...

There is not "Service software" for the CLD. Could add a LON card but you wouldn't really get any benefit and you'd need a way of accessing the card from the LON side. Use Techview for CH530 controls...

5 H.P. pressure washer, pink coil acid (unless it's coated, then Simple Green), and lots of hose. If it's a Microchannel I just hose them out.

CTI's are still available. Installed a couple last week.
Fix the economizer. The boards do fail but typically it is after many years of service.

Cold trap will definitely save you from constantly changing pump oil. Had a braze plate freeze, pop, and fill the refrigerant circuit with water once (had to drill a hole in the compressor to get the...

You have the correct mini monitor hyper terminal settings. Have only used the serial port adapter to make this connection, have never heard of another way to do it. Is your Cat5 direct or going...

Just Google 10k thermistor chart.

Attach the replacement valve while still in the body and bind it. This will allow you to pump down the circuit. There is a service valve upstream of the EXV. Close it then pump down the circuit....

What type of solution are you using?

With jumper left in place unit will change steps every 30 seconds. For those without patience (like myself) take the jumper off for a five count then back on for five to get to the step you want....

Flue gas condensation. Had a School with Geo that couldn't heat. Contractor decided to add a shell and tube HX to the Lochinvar pool boiler to help heat up the building loop. Looked like someone...

TCM's and Varitracs are comm3 devices. The Voyagers can be set up as either Comm3 or Comm4. The VAV Command unit I'm not sure of (not Comm 2,3,4, or 5). Even installing a BCU (BMTX) would not be...

For Windows 7 must be Summit version 17 service pack 10 upgrade 1

Power off /on controller. Check software image. If it is between 4.200.341 and 4.20.343 upgrade to latest image (4.200.344).

Spoke with a mechanic this morning who had a similar problem. The "Magic" liquid ( he would have sworn it was carb cleaner) did the trick.

Had a Aaon (wattmaster to LON through PT Link) that would loose and then regain communications with a BCU about every 30 seconds. Only occured when supply fan drive was above 30 HZ (needed 44 HZ for...

Have retrofitted these into chillers and WSHP/GSHP.

That's an old service bulletin. While operation is the same, part numbers have changed.
Bit of advice. Typically if the filters are going to restrict flow it is usually soon after startup (copper...

Used to service about a dozen first generation recips. Chevy 454 driving a Bitzer. Was able to get most info needed from Teco. Carried a timing light with me at all times. Thought they were junky...

Check the accurracy of your pressure transducers, especialloy the intermediate oil. Just valve off and remove, make sure it reads 0 on the ch530

I've had several 06D compressors I've received from rebuilders that had a higher amperage motor than what I was replacing (same tonnage). Also what is controlling your condenser water...

Google the name Dan Holohan and either buy some of his books or better yet attend a seminar.I went to the Deadman's Steam School about 15 years back.Priceless.

Too big!!!!!!!!!!! Heavy box use of that size(+35 degree box,90dgree cond. ambient) should be about 13,400 btu's.Your box size I can't directly cross reference this is the closest number I can come...

If "all" parts have beem replaced(I hate parts changers:mad:) it sounds like an adjustment issue.Two things come to mind.First everyone loves to turn up the pilot pressure and that gives you a crappy...

Pipe electric boiler parallel to existing boiler with it's own pump w/ integral flow check.Add check valve to near boiler piping of oil boiler and your set.Don't worry to much about a PD switch on...

There has been an issue with the module that controls the timing of the Wye/Delta changeover timing.Bekieve there is a factory bulletin and repair kit.

Did the mechanicals in a small college.Get a call first day of school(work not yet 100% complete at time).Dean's office(of all offices of course) is 90 degrees.Look on the frontend and see a space...

Never had any issues with R-404a equiptment be it coolers, freezers, or ice machines. Just make sure the piping is correctly dehydrated caus' POE don't like moisture.

Most likely a CPR valve to keep crankcase pressure down after unit comes out of defrost.Would only be a capacity(EPR) if you have multiple circuits.

Usually(99.9%) the part that fails is the powerhead(loses it's gas, valve won't open).When handed a valve to replace I just gut the old one and throw the new body in my scrap bucket.Feel people...

Contact the tower manufacturer about the control sequence.The rink I have with an evaporative condenser I have the pump on whenever a compressor is on.If the condeser pressure goes above...

Would highly recommend NOT controlling the pump the way you are describing.Had York do the same type thing a few years back and the owner kept calling saying the compressor would intermittently turn...

3. Contact tower manufacturer in reference to shutting off the condenser pump.Key is shutting off tower pump.DO NOT cycle pump, it will sound like the machine is pumping down and usually will go off...

Charliebear, is it the same area that leaks(RTU)? I see alot of roof leaks that are blamed on the RTU curbs and penetration but tend to find in most cases a roof leak elsewhere.Water gets through the...

Have a 25 ton Aaon dehumidifier that lost both compressors(410a 12.5 ton scrolls) in the first year of use.The compressor housing cracked near the bottom(by crankcase heaters) and blew out all their...

When I use a rosebud (Uniweld) I set the oxygen and acetylene at 12psi.Have brazed 2 1/8" set this way pretty quick.Others in my shop use large turbo tips(a 32) and while they get the job done seems...
