I gave in to the hype and bought an RBI RHP on Thursday and it came today. I have it installed even though it took me awhile, do to the fact I had to put PVC on the inside top of my v400. Anyways I know RBI says as soon as it installed your ready to go. Should I wait a little bit before putting my snake back in or are they in fact safe to use immediately? I have it set to 85 hoping that will give me a floor temp of around 80. How many degrees difference do you have to set yours to in order to get your target temp? It won't even turn on right now bc my room is 86 so I might have to wait till tonight when the temp drops to figure it all out. My probe is about 4 inches from the rhp. It was the best place for me to put it without my snake messing it up.
