My old thermostat is a carrier t-stat and has a jumper wire between o/w2* and L

I am upgrading to a honeywell wifi t-stat, should I install the same jumper wire on the new thermostat?

I have an outdoor heatpump system carrier tech2000ss The furnace is a carrier weathermaker 9200

  • You should read and follow the documentation that comes with the new thermostat. The L terminal is usually used for some type of indicator (usually a light), and may not be on all thermostats. If this is for a heat pump system, the O terminal will control the reversing valve. When it's energized the system should be in cooling mode, when it's not the system is in heating mode. If there is a jumper from O to L, my guess would be that there's some type of light that indicates the current mode. – Tester101 Jul 29 '14 at 15:28
  • I did read the documentation but it never blew cold when hooked up. – Jeff Jul 29 '14 at 15:44
  • I had the white wire hooked into W1 and the orange wire hooked into W2, then I read online that the orange wire o/w2 needed to be hooked into W1 o / b on the new thermostat - which I did, and the white needed to be hooked into the W2/Aux terminal - I did this and it still blew hot for the AC. – Jeff Jul 29 '14 at 15:45
