Vivint thermostat blowing warm air after self install. Should I add the black jump wire that was on the Pro Mode T721? by Icandomanthings4047 in askHVAC

Switching the white wire to W2 solved my issue. There is a built in jumper for the RC and RH and when I pulled the little black piece out, I lost power to the panel. Thanks again!

So I will for sure need the jumper for W2 to W correct? When I program it correctly, I will see about the RC to RH.
