your right for the most part but if you want cont cold on temp setting run it 7 clicks up cause where you have in coldest setting its at 60de and take forever to start where if you go 7 clicks it will start and stop and keep you cool
So my question about this feature: when we turn the AC on in the bunk, is the air being blown in from outside or is it being circulated? I don’t want to set the optimized idle if im going to wake up to the cab being full of exhaust…or not wake up I should say lol
Thanks for the great question, I called and talked to a service tech and they said that they are 100% filtered. You are perfectly safe to run it that way without fear of harming yourself.
Quick question, the only way I get my apu to run continuously is by doing the optimized idle thing and also keeping my key in the on position. Is this correct? Otherwise, the apu just shuts off after 5 or so minutes. Am I okay with just leaving the key in the on position and running the apu all night while I sleep? (This is my first time working with any apu of any sort)
Good video thank you. If only all models were the same. The 2024 model I was driving last night has a different configuration than yours and does not work the same way
OFF- cranks once batteries are under 12.2V. Runs for 2 hours. ON- cranks based on interior temperature. The temperature is controlled by sleeper temperature gauges.
The AC will run as long as you have bunk control turned on .. in other words, the fan. The AC will run independently and the truck will start up when the battery is get low.
No, if your truck is equipped with the Park Smart upgrade you have 4 extra Group 31 batterys that run just the A/C for the bunk. They are usually housed in between the frame rails right behind the cab or in a side box. I'm sure you've found them on your pre-trip by now
Ive messed around with my opti idle the past 2 days and its only worked once. I set it to idle and then my bunk controls do nothing and there are no lights on the controls.
When I turn on the optimized idle the engine turn on for some time with the fan&ac on then when the engine auto shut off both bunk and front fan shuts off as well and won't turn back on unless I manually turn the ignition key off then back on again it's frustrating and never use the optimize idle for this reason
Yeah it can be tricky, it all depends on how it is set up through your company. However, I have found that you must make sure that the key is turned to the on position, Not running. Just turned to the on position.
Update: after few days opti idle finally came on second time after shutting down once. It's only 72 out n working. Wish I knew what I did for it to start working correctly
When I attempted to turn on my optimized idle, the AC in the sleeper won’t turn on, and the controls in the sleeper don’t do anything but the controls up front do.
@@SeamanRunescape I'm sorry to hear that. Make sure you have the key turned to the on position, but don't start the truck. Also, some units you need to have the controls switched to the back which is usually done on the front controls. There's usually a switch. If that doesn't work, You can always talk to your company's shop or the truck manufacturer.
@@mercpindi5522 If you don't have the optimized idle, You might be able to just engage the cruise control and hold it up until it reaches a thousand RPM and then just let it keep running hopefully.
@@mercpindi5522 well that sucks. Have you tried the trick for the trailer If you are attached to a trailer, disengage your truck parking brake and just stay parked with the trailer brake.
For some reason, when i cut on opti idle, the unit in the back will only run to get it cold. Once the engine cuts off, the air does too. The air has been off for 3 hours now and it's 80 degrees in this truck. Am i doing something wrong? I feel like the a/c should come on much more frequently, not when it's over 80 degrees
@CarnivoreWerewolf yeah, just the key is on. I'm going to take it by the shop later. I also have idlefree system but it doesn't work. The inverter doesn't work, I think the previous driver blew a fuse
On that I have no clue. I've never seen it do that. I don't know if that refers to the battery where it's saying crank alarm fault... I would ask your company mechanic or a mechanic for your truck manufacturer.
Well the problem I’m having is I use my bunk heater for heat and I use the Opti idle for cold . I’m curious to know if I can use the Opti idle for heat but the problem is that the truck doesn’t stay on for heat only for cold.
@Unrivaledthings I'm having this issue too. Did u ever figure it out. Heat blows hot with the truck just running. But when I use the optimized idle the heat instantly switch to cold air
I’m so confused 😂. I had a ‘20 freightliner with opti idle. I left interior comfort OFF and the ac or heat would work just fine and the truck would crank after 6-8 hours and run for 90 minutes or so to recharge.. then cut back off. PERCECT AND EASY. Now I have a ‘24 and it’s IDENTICAL to the ‘20. Identical!! Except that in the OFF setting the ac only works for 10 minutes then it’s just a fan. The heat works fine. Truck cranks to recharge hours later. To use the ac.. I have to use interior comfort ON… and the truck runs and never cuts off. Wtf? That makes no sense. If it has to continually run, why have this system?
Yes, anytime that I use music now it is extremely low. That was one of my first using music in the background. It's a live and learn experience. Thanks for your comment.
that "music" in the background is extremely annoying. I couldn't even continue watching your video with that annoying music in the background. - and by the way you never mentioned anything about whether you leave the key in the on position or turn the key off
I'm assuming your heat controls are set on the red hot all the way? If not, make sure it's turned all the way. Otherwise it might be a heating coil issue.
Thanks man, this is my first year trucking. This video saved me. Now i can get some quality sleep without waking up early because im freezing 😅
Thanks a lot , i was suffering from the heat at night ,you saved me

Thank you just got into a new truck this helped a lot !!!
It used to be, 10 years ago it started and stopped every 30 min. It really isn’t bad these days though, my truck starts once in 10 hrs.
Wow- great detail. You really made it easy👍👍👍 thanks so much

Great information

How long is that ac supposed to run ? Is it going to start the engine every time the system calls for ac?
The AC will run as long as you have bunk control turned on
.. in other words, the fan. The AC will run independently and the truck will start up when the battery is get low.

Will the Engine stop and start to keep the desire temp?? And how to set the Nobs for that?? So it's not too cold or hot??
Thanks
@@alphamaletony8899 It should, That's the way it's designed. You should have a temperature control knob in your sleeper area
I have 2024 same Nobs set
I notice your at the driver's dash all yours are turn off counter clockwise.
Did that too.
How many hours it can work ? Unlimited?
Unlimited
hi sir, my truck is 2021 model, I set battery mode, and drop down 12.2 will start, but non stop always run, do you think any problems?
Thank you 😊
Ive messed around with my opti idle the past 2 days and its only worked once. I set it to idle and then my bunk controls do nothing and there are no lights on the controls.
Sorry to hear that. Yes, it can be frustrating.
For this to work you’d need to have a battery APU?
No
Very helpful 👍
What if not available?
It depends on your company you work for some dont have comfort to select from
@@deznuts721 that is very true.

Why does it say crank alarm fault optimized idle disabled?
On that I have no clue. I've never seen it do that. I don't know if that refers to the battery where it's saying crank alarm fault... I would ask your company mechanic or a mechanic for your truck manufacturer.
Ty sir
Why doesn’t the heat blow really hot ?
Do you have your temperature? Selector all the way up to hot? If you do, there may be a problem with the heater core.
Well the problem I’m having is I use my bunk heater for heat and I use the Opti idle for cold . I’m curious to know if I can use the Opti idle for heat but the problem is that the truck doesn’t stay on for heat only for cold.
@@Entrepreneur5480 interesting. Well, as long as your bunk heater works... Then just use the Opti idle when you need cold air.
