Troubleshooting

My heat pump cools in heat mode or heats in cool mode.


If your heating and cooling are reversed, then your wiring in the O/B terminal is probably reversed; proceed through the following steps until the issue is resolved.


  1. Press MENU to enter the configuration menu.
  2. Press NEXT to advance through the menu until you get to menu number 5.
  3. Switch the setting from “O” to “B” or “B” to “O”.
