1. can you control the temperature from the top of the spa or do you have to take off the panel and adjust the temp like in some of the older spas? That is a deal maker if you can adjust from the top? 2 Does the cover have straps that lock it down (so that wind does not blow it open in winter?) We had a hot tub prior to now and there is a 220 disconnect can it be wired to that? My husband is a licensed electrician so I assume that can be done? thanks
