Ok just got it yesterday. First impression is what a nifty gadget! It does seem a little light weight in the construction. I would like to see the case made a little sturdier. But it does have a 3 year warenty so what ever. Programing seems simple. find the button for the function you want (there all on the front 15 of em) and set up or down. Stats are as follows. Power input volts 100~265 volts, Cirtcit breaker rating 15 A/ 240 v~, Output receptical rating 15 a/ 120 v~/10 A 240~, remote sensor cable length 16 feet, min max operating temp 32-120, min max operating humidity 0-99 rh, temp accuracy 1.8 f, Humidity measurment range 10 - 95%, humidity accuracy +/- 3%, Light sensor sensitivity Adjustable, c02 accuraacy +/- 75 ppm, co2 measurment range 0-2500 ppm, co2 sensor warm up time less than 10 min, computer interface (optional rs 232 / 9-pim D sub, weight / dimentions 8" x 6.5" x 3.5" 5lbs. Works fine so far.

Really. Then why aren't we all dead?

If you want to start another thread about CO2 then please do so otherwise let's keep this one about the CHHC-1.

cause no one ever uses those rediculous co2 levels... do u think those links are blowin smoke?? dont believe me then, ur the knowledge seeker, do ur own investigating. guarentee everywhere u look the info will be pretty much the same...

Has anyone noticed a difference in temperature readings between the CHHC-1 and a standard Ecoplus Digital Therm/Hygro? I put them right next to each other for 2 hours and the Ecoplus consistently reads 2-3 degrees lower than the CHHC-1. Any one know what the rated accuracy of the Ecoplus or similar device is? The CHHC-1 manual states that the temp is accurate +/- 1.8 degrees. Seems like for this amount of money we should have gotten something that was accurate within a degree but maybe that's just me being overly critical.

YOu need to use power relay switches to run high amperage items like A/C units. This is pretty much standard for this sort of thing.

You should really pick up a high amperage relay for the A/C and other high amperage items. You don't need the the same brand they are all pretty much the same. They are cheap and will take the power load off of the controller enabling you to run more devices. My controller is working fine I ordered another one to run my Hydrogen LPG Generator. I have been running mine in a 1800 CU ft room with the controller set in fuzzy mode at 1350. It's never more than 200 ppm off unless it's building back up after a ventilation cycle.

To power high amperage items with any of these controllers you should use a high amperage relay. its just a plug with a separate power distribution box. it has a piggy back plug and you plug you AC or what ever into the back of the piggy back plug and plug it in to the wall. you plug the other end into the controller. this keeps the draw off of the controller and on the relay.

How much do they cost? Can you get them at any hardware store (Home Depot, etc.?)

They are about $100 bucks at this web site but I know you can find them cheaper.I am sure you could make one also if you were Remotely crafty. You don't need to but the same brand any brand will do. http://www.hydroponics-garden.com/xcat459.html it's the power expaneder I would have found a better deal to link but it is like 5 am here now and I just woke up.

LOL. 5 am is EARLY! Thanks milowerx. I will shop around and see what i can find.

My grow room is 10x10x8. I have a 50lb CO2. I've been running my an average of about 1250 ppm. Running at that ppm my CO2 tank lasted about 3 weeks. Seems kind of short for a 50 lb tank but since it's my first grow I have no idea. There are some holes and things that I need to fill and patch but how much CO2 are you using? How large is your room? What ppm are you running? How big is your tank? How long does it last?

It seemed kind of cold in my room so i put an Ecoplus therm/hygro in the room and put the remote sensor right next to the CHHC-1 sensor and most of the time they are within a few degrees of each other but I've noticed at times they differ a lot (like 6 or 7 degrees difference.) Has anyone else tried comparing readings from other therm/hygro devices to the CHHC-1? I attached pictures from two different times when they varied a lot.

I gotta give that a try and let you know. the Mmanual sez 1.8 F That seems like alot more.

Yah, and the tech specs for the ecoplus say temp accuracy is 0.1 degrees Celsius...

The reason it's a big deal for me right now is that I am fighting a case of downy/powdery mildew. Totally sucks. So i've sprayed them down with mildew cure but the environmental parameters to avoid mildew are temps above 76F, RH less than 45%, and no excess nitrogen. So I've got to make sure that my temps are accurate.

If you do get a chance to test yours out that would be keen. I may just have a CHHC-1 that isn't calibrated correctly. The temp readings seem to differ more at lower temps too...

In case anyone is interested I found some software that will capture readings from the CHHC-1 and exports the data to an Excel spreadsheet. The software install is in Chinese or Japanese but just press the "next" button and it installs fine on Windows XP. The program itself is in English. http://drop.io/whl70rf/

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

The only thing worse then a moron is a moron who acts like an asshole.

KnowledgeSeeker is correct in everything s/he said, and I can vouch for that because I also run a sealed room (have exhaust hooked up, but never use it).

And I've run my CO2 up above 5000PPMs to kill bugs and my plants (and I) somehow survived (with no adverse effects).

But to the point of the thread, I have a CHHC-1 and it works like a charm - best investment I've made in my grow, IMO.

Check out the link in my signature ("New Setup") to see it in action, if you're interested.

do i have to un rar it or did u just give me a virus??

I'm not sure what "un rar" it means, but that file looked a little shady to me, so I held off on downloading it - has anyone done that successfully, and also what cord is needed to download info from the Sentinel?

Would I have one lying around, or do I need to run out to Best Buy or something?
