Yes, you are correct, it is a VAV.
My SFS.S is set at NO
My SFS.M is set at 0
I have a Carrier 48AKD060 and u cannot get the econ working. I have verified my parameters with tech support. The main base board was replaced due to the eeprom failing. The run status shows the...
I'm a big of Nylog, its like snot. It's like a heavy-duty superglue which stays flexible. Leak lock will eventually crack especially ifused in close proximity to compressors (vibration).
Absolutely, you can use whatever air you want. You wouldn't want to use too high of an air pressure (20-25 psi should be sufficient).
It's usually the tubing, not the sensor. Most of the time people will install a "T" and put a rubber plug over the "T" port, these tend to dry rot and crack. If your lines are good, then check the...
neilh20man, you have to update your info and include an email address in it. You will be unable to post your email in the thread. I will send the info, but please add your email into your profile.
I'm trying to locate the manual for this machine and am having no luck on-line. To top it off their office is closed now. The mod# is: TS015MR404A2. I'm specifically looking for its clearances. I...
Wireman3736 check your email, I just sent it to you. Take care.
ZeroCool, what I mean by tested was I disabled the economizer until the unit got up and running (90% or better on the sf VFD) and then enabled the economizer again. It seems like the first time the...
Okay everything was fine until two days ago, unit was down again. I bumped up the VFD speed and decreased its accel time to ensure the switch makes within the 40 sec time limit. Today the unit is...
You want the box to fail to cooling:
1) Set damper N.O.
2) You want a N.C. valve
This will give you fail-safe to cooling.
Now with the R.A. stat, as you call for heat the pressure will be...
Thanks slctech, it does have vfd's for each fan. I'll look into the aux switch and apply for Pro Status.
The last couple days the unit has been having an alarm due to the EF not starting (failure). The wiring diagrams are illegible. If you kill power it will start and run fine until the next day. I...
Thanks catalina_mike, it was roughly a 15' run so I reused the existing wire and the baud rate is 38.4. Thank you.
45 it definitely reads in the program, going to get a RSPRO now. Baud rate set and jumper moved. Thanks for the help guys!
Got it thanks! Without replacing the stat,will it still function but only the LCD won't work? Or will it read incorrectly?
Thanks Kontrol, one more question: What do you do with the UNET wiring?
The controller is already emulated.
I am replacing a U341+ controller with a ZN341+ controller. Will the LSPRO stat work? The new controller has a RNET which has a 12V terminal, but the LSPRO has a LS5V terminal. I am assuming...
picnik, thanks, you weren't kidding! Should be a huge help.
Mr. Greenjeans, thank you also for the missing piece!
That would be awesome! I'll have to do it after work and when I get home, the internet on my phone doesn't let me edit my own profile. Thank you!
I've inherited a building with some older Staefa stand alone controls and can't find anything on the web to help me decipher how they operate. I mean I get the gist, MA controller, min OA, DX...
BTW, It's a brand new actuator.
Just dealt with an Invensys TB158-017 stat controlling 2 3-wire floating actuators and am having a problem. When I call for cooling the chwv opens and the hwv closes. Great, right. When I call for...
Sorry, reading the correct temperature
Sounds like the r/c is not properly calibrated or have you checked to make sure the transmitter line is hooked up and reasons the correct temperature?
