Its 100 % outside ahu for building hallway
Even the actual switch and reset, I have one mounted right next 2 the oa damper and trips, of course the cap tube is fed in front of coil but there's no duct for it so air is being fed thru the...
Is it possible to mount one in the ahu ?
thanks guys, crazy how important something is to a system but yet theres probably alot of guys dont even know about it or even think twice about it
i know i know stupid question, but if im not sure of something im gonna ask somebody
Do u need it
What is the purpose of a distributor connector for a hgbp ?
No , I know you need one there for isolation when you have a LLSV this is on the pilot tube -equalizer line
Why would you install a solenoid on a equalizer line for a hgbp valve ?
yea true , but i'll have to learn while on fire like usual , abb does have good tech support from what i hear though
The drive is controlling itself
Jayguy , maybe but either way I wanta pull the gas and put new in
Jpsmith, hi pressure was tripping when I got there, I pulled out 20'lbs just to get it to run , then checked my subcooling , it was 25*f + , so yeah I'm sure the freon is shot, FYI it's a 50 ton...
so i pumped down the freon into the condenser, ran the fan for 30 min. then checked my liq. press., it was 240 psi and saturation temp was roughly 114*f, the outside air temp. was 94 * f. should've...
Also I'm sure the drive to run off supply can macro
So how can it be commanded to run at 35 hz from a my static sensor and running at 60 hz
isnt the line with 60 hz saying the motor is running at 60 hz
ok, so why does it change when i adjust it with the arrows and also change the 1.5 '' h20 line
when i use the up/down arrows it changes the 58% line and the 1.5'' h20 line im assuming the 1.5'' h20 is my setpoint for duct static, also when i pulled the tube off the static sensor the line with...
so i found out its supposed to keep suction pressure equal in the sump and prevent pushing the the oil out of the one compressor thats not runnning
Is it necessary to have
so ive noticed on some tandem setups, we will have the oil equalization line but also a 1/4 tube piped to the bottom of both compressors, literally right underneath the sump. why is this there?
thanks controlfreak, nice video and easy to understand
thanks control man, i will check it out
