- Today we go through a Lennox package unit that is no longer communicating with the energy management company. We learn a bit about the lennox humiditrol option and a little bit of other stuff. Enjoy- sorry for the poor audio at the end.

I love how the way you explain everything brother much appreciated 💯🍻
EXCELLENT video, many thanks!

The ambient pressure switch maintains pressure above freezing. Like on a server room unit that runs all year. On R22 the condenser fan should come on around 275psi with a differential of 50psi. So off around 225psi. This keeps the evaporator temp above 32 degrees.
Thanks curious nicely said
On the data plate, the item labelled Evaporator is the indoor blower motor
I always hate the unknown variables of turning up after someone else has walked away with the unit turned off. You wonder if something's going to go bang when you turn it on again or if there's a miswiring booby trap.
Your sound is really good with a compressor and fan running. Are you using a phone to record? (I use Moto G's for my own videos.)
Your exactly right Clive- theres a bit of nervousness when you start playing around in a machine that is just left off, never know whats going to happen
I don’t think there’s any pistons in that scroll compressor.
For the EMS board.. take that fuse out. Then you can jumper out the relays you want to test.. example: stage 1 heating or cooling stage 1.. ETC. on that relay you will see the 2 male spades on the same relay. jumper them together as connect them on the same relay.. voila. I find testing the cooling stage is best for last when I test for all
Bloody control board with no screen , just switches and codes ,urgh !
I'm gonna stop complaining about the RTUs I work on , they might be complicated, but at least they have a controller with s screen and buttons !
Kudos to you fellas !
Are you working on the prodigy system?
@@curioushvacguy6876 not at all , I usually work on systems with Carel regulators or such , the nice thing is they have a screen and buttons 👍
Great video.where can I get a manual on this unit like the one U referred to? Just to have a better idea on these units
worst place i ever had to get to was a euipment room above a jail, cell on second floor, hvac on third. to get there enter the basement and climb a 4 story ladder, they had a winch to bring up tools and equipment. this whole system was ground source.
Wouldn't the reclaim coil be a condenser since its routing hot discharge gas through that coil downstream of the evaporator?? Evaporator dehumidifies and chills the air so the reheat coil uses hot gas to raise the temp back up so you have dehumidified air at the temperature you want? Love the videos man!
#42 Thumbs up I was about to lose my lunch on that ride up to the roof....:)
So that low ambient switch acts like a head master?
Any idea why that compressor was so dog on loud?
Doesn't the reheat cool come AFTER THE evaporator, not before?
Where do you find the physical manuals?
U are looking at low ambient switch , it is basically a cfan cycle switch .
lol, I swear I work for same company broah. I take care of Chicago, retail commercial and deal with same shit. I've been doing this over 20 years though so I'm sick of it.
So is that second evaporator like a reheat coil?
Should have finished watching the whole video before I commented.
On novar u have to jump idm fan and y1 .
Goes through the evap 1st not the reheat coil
Should have checked ur amp draw on cfan .
👨🔧🍾
Thanks
Dude it’s in free cooling
Comp sounds like crap.
Novar crap , ems is useless , corporate micro management.
