Instance buddy help

Using instance buddy / grinding bot atm on mixed mode. The grinding part is working fine, however when a dungeon queue pops and I enter as a healer my priest just starts damaging everything and not actually healing...So essentially my group wipes every pull and I just keep on dpsing. Any ideas on how I can actually heal instead of dping? Currently playing on a priest at level 20. Thanks

 

check setting on talented in plugins so your on heal not DPS

 

There are no options in the plugin section that I can see ?? :S

 

I'm on a priest. And I don't know what CC, have no idea how to set it up :S
