Better solution for a heat shutoff switch

I have a baseboard heater thermostat hooked up inline before the power to my ballasts so in the event of an air conditioner failure the power will cut off to the lights and my plants wont burn and die. This is the thermostat I have now:

I am about to hookup my co2 burner and run at 83-85 degrees F and this unit shuts off at 80 degrees. I love this unit because it is so cheap and it works well. What can I get to get the shutoff temp to 90 - 95 max?

I have 5 of these http://www.ebay.com/itm/Solid-State-Relay-SSR-25DA-25A-3-32VDC-Output-24-380V-AC-Solid-State-Module-/130905531225?pt=LH_DefaultDomain_0&hash=item1e7a93e359

Can I just get a standard thermostat and hook it up to this?

burn and die...? they wil sruvive fine 100 plus for 24 hours +.

If youe ac is shutting off, better fix the root of the problem...

It died in 2 different grow locations and the temperature went to 125 in 20 minutes and by the time I discovered it my 55 gallon drum full of water read 120 degrees.

first off what are u running that makes heat of 125 degrees

a good cool tube .......with a strong inline fan can handle/ adjust for most temps and keep the system cool
i have 2 600 watt in a 4x4 tent and i am pumping in exhust air from a 2nd tent(1000w) into that tent my temps are running 92 .........using a 6 inch 400 cfm inline fan

here this is what u want

this will shut off anything it is plugged into if a temp goes above a set temp .............that is what is designed to do

if it is Co2 burner that is getting it that high u need a controller system for that ..........if the Co2 ppm are to high then the venting is not recycling the air and it should shut itself down becuase the Co2 ppms are to high

I am running 8 600 watt vertical lights at a time in flower with 2 18000 BTU mini splits in a 19' x 13.5' x 7' room. The temperature just starts to slowly creep up. I may need to reposition the AC units or get a more powerful one or put in some cool tubes.

Ok, for starters it sounds like you have enough AC in there. Are they set to run max or in economy mode?

I use three tons 36kbtu in a room with eight 1000's and its perfect. With a CO2 generator and a 110 pint dehu. No venting hoods just AC.

Shoot a pic of your room, air handler locations. Are they really mini splits or those junk portables? You got a set of gauges to put on the condenser so we can check your pressures / differentials?

This is the system I bought - http://www.thermospace.com/ductless_split/ymgi/tri-zone-45000-btu-1800-9000.php . The remotes look a little different but I bought it new this summer. I had a professional (and friend) install it. It works well. I have the 2 18k btu units on one wall in a 19' x 13.5' x 7' room. The 2 units are spaced evenly the long way on one of the 19' walls. They are up high. The house does not have a heater and the veg and fruiting room are next to each other. I am going to put 8" ventilation in the walls between the 2 rooms and vent it to all the other rooms in the house. This will defiantly improve the efficiency of the air conditioner units. The temperature is at 77 with 6 of the 600's on. I had the dehumidifier blowing hot air in the direction of the thermal shutoff switch so I imagine that had something to do with it. I moved it to the other side of the room. I am going to move forward with making my own thermal shutoff switch somehow. I have the parts I think I need. I just need to test them. I purchased a digital thermostat and a 50 amp solid state relay. If an off the shelf thermostat sends signal at 24v dc then I should be done.
