Hello, Folks. I am installing two NEST E's for a customer. I have installed these before but this order is a little unusual. First he has two existing thermostats for each floor with one heater/AC unit. And I am pretty sure I can just replace the two old thermostats with the new ones. But what's been bothering me is this: When I opened up the old one, I not only saw the usually jumper from the Rh to the Rc, but two extra jumpers with what looked liked (red) capacitors. I've never seen that. So now I'm wondering if I should jump the same into the new NESTs or not. I'll be contacting NEST support on this soon but wanted to know from anywhere here what those two capacitor looking like components are and their functionality. Help!
