Sentinel climate controller reviews?

Hey all


doing my research on climate controllers, and eventually came upon this one. It's got the temp and humidity control of course, plus a CO2 controller with a CO2 PPM meter in the remote sensor. every other controller seems to have the CO2 meter as a 500 dollar add on, a total rip off if you ask me. 600 bucks for everything in one package seems a good deal.

so, anyone have any experience with these things?

Sentinel CHHC-1 Day/Night Environmental Controller

Yeah i was thinking of purchasing one of these. I don't know if it has an intermatic timer with alot of events, but if it incorporates into this box, i'll for sure buy it for my next cab.

I dont believe it does...it controls temp, humid, co2...gotta run lights and hydro stuff separate, but this is perfect for me. getting everything necessary to do these three things cannot seem to be found for less than a grand.

Well After looking high and low for info on this co2 controller I decided to try it out. I paid $509 with shipping from eBay. It really seems to be the best deal out there for controlling co2, humidity, and temp with a photo sensor. I'll let you know how it goes.

I just purchased a CHHC-1 as well. I got mine for $450 here: http://www.igrowhydro.com/blog/711/sentinel-chhc-1-coupon/

Keep me posted as too how you like yours and what your setup is and I'll do the same. I have a 10 x 10 room with 4 x 600w lamps. The room is "sealed". I have no intake and no exhaust so the the plants can just marinate in the CO2.

The controller is capped at 15amps, which means it cannot control an AC unit (most of them). At most, it can control a dehumidifier, but if you're also using it to control intake/exhaust fans, you might be cutting it too close.

I use separate controllers, the CPPM1 and the EVC-2.

i was checkin out the chhc1 some more... the specs say that it runs off of 15 A @ 120 V (from wall). but itself has heavy duty power outlets with 30 A relays. did someone tell you they were having problems powering their equipment or did u just assume it wouldn't work? or did u have 1?

I have a CHHC-1 with a 11,000 BTU AC unit and a CO2 regulator plugged into it. The AC is 12 amps and works fine.

I do have a Dehumidifier but it is not plugged into the CHHC-1 because it doesn't revert to the last setting when the power is cut off and turned back on (be sure to check that when purchasing AC and Dehumidifer components to be connected to the CHHC-1).

awesome thread.. I was looking for controlers also.. Looking to run an ac,dehumid,c02 i wont mind spending the 600-700 bucks just want the best.. Let me know how u guys make out.. show some pixs too.!!

The controlers are good if you need to remove element from the room not good if you need to add elements ie cant keep humidity above 40%

i had the same problem with that unit. had to redesign rooms cold air control. I have a the $250 unit sitting on the wall with nothing pluged into it!

Hey guys great shit.....just got th CHHC-1.....as i saw previously someone said they let their plants marinate in the co2....so i DONT need and air in and out.....IF i use an ac correct? im new to this but im trying to get my equipment dialed in and the last final venting cuts made....I dont wana make unnecessary cuts.....im running co2 as well but a little hazy on the exhausting in and out part...i planned on having my lights vented...durh...but as for my room i have no ac but co2....little help im goin in circles

so i DONT need and air in and out.....IF i use an ac correct?

Absolutely correct. Some will argue that plants need fresh air but I disagree. Plants need CO2, oxygen, and air (not necessarily fresh air). As long as you are providing CO2 they generate more oxygen than they use so you're set.

Unless you are planning on using flourscents or LED then you will need an AC for a sealed room. Even air cooled MH and HPS generate a considerable amount of heat. AND the AC must be a dual hose type vented outside of the room.

i completely disagree with no exhaust... with a portable a/c unit, u can get away with no intake, but the air that it exchanges and kicks out will STINK! unless u live in the wild, that might not be the best idea. besides, no or little exhaust is extremely unhealthy 4 plants, no matter the quantity of co2 injected. and if u inject too much co2, plants will burn (ppm meter is a must).

the only really safe way to do co2 is to either have a co2 injection/exhaust schedual with 15 or 20 min of injection with exhaust off, then 1 or 2 hours of no injection and constant exhaust, repeat the cycle while lights are on, no injection and full exhaust while they're off... or get an environmental controller that coordinates injection and exhaust 4 u....

With a sealed room you still have a CAN filter with a high CFM fan that scrubs the air in the room which removes all of the smell.

Totally false. As i said before, plants need CO2, oxygen, and air. You provide the CO2 and they use the oxygen to produce more oxygen. There's a good article that explains it in more detail here: http://hydroponicsfriend.com/archives/39 I'm curious, what do think is in "fresh" air that you wouldn't have in a sealed room?

keeger123 said:

No, plants will not burn from too much CO2. You can flood a room with 10,000 PPM to kill spider mites and plants will do just fine.

keeger123 said:

I do agree that a PPM meter is a requirement for proper CO2 supplementation.

If you are paying for CO2 why would you want to suck it all out of the room? Especially if there's no good reason to do so.

keeger123 said:

I totally agree. Plants use CO2 during photosynthesis which cannot take place when the lights are off.

Grrrr fuck it i have tried five times now and keep fucking up before i finish my post and have to start all over agian so this is the really short version grrrrr



Test, never tried this before.... permalink..... hope that works

Then theres his nice ass mother board check that out

I really like http://www.autogrow.com/1_intelliclimate/intelliclimate.html, http://www.amhydro.com/index.php/Grower-Gear/IntelliClimate.html, not sure it does every thing by the looks of his mother board it takes a little more.

nice thread

itll somewhat remove stink. guarentee u would still be able to smell it in exhausted air though. it'll be half scrubbed air and half stinky air.

fresh air is air that hasn't become concentrated with water vapor and other unwanted byproducts exchanged during the photosythensis process that inhibits mold and mildew growth (oxygen is just the major product chief). a scrubber will not remove this and an a/c unit doesnt have sufficient exhaust to effectively reduce this.

yes, too much co2 will burn. i learned that in organic chemistry. where did u learn it?? even ur gay little article says too much co2 is a bad thing....

ok, first u fill the room up with co2 for 20 or so minutes, then exhuast with co2 off for an hour or so. u honestly believe that they need a constant co2 boost with no air exchange??? marijuana plants can not physically consume co2 in an environment higher than 1700ppm, so anymore never gets used. THAT's a waste... do what the hell u want, my plants will be twice the quality, and quantity

It will remove the same amount of odor whether you are exhausting outside or inside. A proper sized CAN and fan will remove ALL of the odor. But in a sealed room you are not exhausting outside of the room. period.

Which is exactly why we use dehumidifiers.

Yes, 100% CO2 will kill you and the plants. I said up to 10,000 PPM would not kill a plant NOT that you couldn't kill a plant with CO2. It is a bit hard to do with 20lb tank and a leaky room, but still be careful, it could happen.

keeger123 said:

1500 PPM is not filling a room with CO2 but yes you want to maintain a constant 1500 PPM. Which is exactly what the CHHC-1 does. You set it to 1500 PPM and connect your regulator and it measures and makes sure the room is always at 1500 PPM.

How much CO2 they can use depends on their other limiting factors such as light, water, and nutrients. Generally around 1500 PPM should be enough.

Thank you, I will. I hope you have a great harvest.

Now, let's keep this thread about the CHHC-1 and leave the sealed room debate for another thread.

the room will continously produce more stink, so unless ur srubber is right beside the a/c, then it will be mixed air and it will have a smell. its called common sence...

my room is completely sealed with poly and silicon, AND there are ducting vents in and out of my room for intake/exhuast. i think we have different ideas about what is ment by a sealed room, i.e. the idea isn't to eliminate the exhaust.... my intake and exhaust are on timers and they will coordinate with co2 injection so the plants have the best of both worlds.

ok, since it's obvious you dont know anything about co2, i'll be nice and post a couple little links to save ur life...

http://www.greenmanspage.com/guides/advanced.html

http://dhs.wisconsin.gov/eh/chemfs/fs/CarbonDioxide.htm

co2 level in atmosphere is about 300ppm, 2000ppm WILL BURN PLANTS. 5000 ppm WILL KILL PLANTS and prolonged exposure to this environment will give humans BRAIN DAMAGE. but prolonged exposure to an environment with higher amounts of co2 than 5000ppm can KILL HUMANS. 10000ppm??? thats only 0.01% concentration of co2 in the air but CAN and WILL KILL.... now i'm curious.... do you even understand how ppm is measured?? u said co2 is harmful to plants and humans when the air is almost 100% co2!! come on now... that's complete nonsense. brain up, free ur mind, and quit regurgitating what ideas u formed in ur head... ur advise could kill someone! co2 can be extremely dangerous if low enough levels aren't maintained. This is also why people exhaust their rooms. the articles i just found 4 u even talk about need for proper exhaust and air circulation...

so 1500ppm is more than enough co2 in the room

the reason i was drawn to the chhc1 in the first place is the fact that u plug ur exhaust fan into 1 receprical, and co2 device into another, and the chhc1 automatically kicks one in while killing the other. so i'm pretty sure the room's ment to be exhausted

this must be ur first grow with co2, otherwise u'd be a vegetable or dead.........

keep seeking knowledge....

oh, and i wasnt lookin 4 ur approval or disagrements with my posts. i know i'm right, and all ur responses have either been stating the obvious or completely out to lunch... i'm pretty sure ur the last guy here qualified to give advise on co2 since ur page says this is the first time u've grown, at least at this level....

p.s. don't be such a smart ass next time and i'll try not to make u look like too big of a dumb ass, are rooms arent too different, with exhaust, i think u'd have a great setup
