snowschool, the unit you may use has electronic controls, as most if not all that size do.
The only problem with an electronic control, as opposed to a manual control unit, is that when the power goes off or surges for a second, the controls will default to a shut off position. This could cause your grow to get cooked. I recommend anyone using an electronic control unit to also purchase a UPS (uninterrupted power source). The UPS will keep the unit running for a while even if the power goes off.
The RG-51C model is a 5000btu on the same page. It has manual controls. Two of those would probably do the job.
The better you have things in the room the easier to cool. If you cool the 1000's with a separate duct and fan, keeping the grow room cool is easy, and you may be able to do it with one 5000btu unit.
