Temperature controllers- are there any that control day and night temps independently

[rr14]

I currently have a cap xgc1 extreme greenhouse controller. While this is nice, it doesn't have independent settings for day and night temps. This is an important feature to me because when the c02 is on, I want it about 85. At night I don't want it even above 77. Are there any controllers that take the day and night settings into consideration? If so, can you post model #'s? I'd love to take a look at several of them and pick one out.

You can use a RANCO two stage controller;

Two relays, one controls heating and other controllers cooling, but both do the same job, keeping room at two temperatures at different times.

You need something that has an optical sensor. A Sentinel model of some sort will do the trick but there has to be other manufacturers with similar gear. I'm pretty sure a friend bought a UTC-1? I dunno...something like that.

nondual... that sounds like what I'm looking for. Something that has a optical sensor to differentiate between night and day.

i use a SENTINEL CHHC-1 it also dose set point CO2 ppm contorl and Humididty. WOrks on a photo sensor. And has both Heating and Colling... You can find it under 500$

Only problem with the Sentinel, and hopefully they fixed it, is the breaker would pop regularly and it's just a bad design. My buddy bought one and it was popping running an AC unit. It was replaced and still a problem. Finally the store owner checked into things and found the company is aware of this and sent a modified unit. Just something to ask about. I think the company would even offer instructions for a home fix. Ever since the unit was modified there have been no problems. It's got a heat/cool mode and stuff...very nice little unit except the temp sensor acts a little slow IMO. I also set my buddy up with some Johnson Controls A419's and they're definitely a bit quicker.

i just got a chhc-1... not only does it do everything you want the new ones have a serial port on the side... they're making software for free downloading eventually that'll mate to it

i thought i needed separate day night temps, but now have both day/nite set the same.

Those Ranco controllers look quite nice....I was going to buy one some time ago but the homebrewing place id seen it at ran out and i cant find anywhere in the UK for em now... No worries though coz i got the ATC800 which has heating and cooling relays in it and a remote probe...After testing it for a week with my super speed controller im ready to put the thread up...just wanted to be sure it works...
My next project is actally going to be a day/night switch... im going to use a relay and one of these
http://www.screwfix.com/prods/11330/Lighting/Floodlights/PIRs-Photocells/Photo-Cell-5A-Load.... Ill fix it to a small plastic box with the relay inside and have cable glands, and a power in cable and power out cable...trailing socket to plug things in.ill put a switch on the front so it can be set to turn on or off with the lighting(using relay with NO and NC contacts) or maybe have 2 outputs one wired to each contct so it can do both....
you can buy nice little photsensors meant for terrariums though the habistat sun and moon switch range comes to mind.
