Help Please ! heat pump tstat wiring issues Maybe?


ok so.... what is is listed below...
but when it was wired up it would run the heat pump em heat and cooling b4...... but maybe that is why it keep killing everything (not i also notcied that the stat wires out side when i replaced where passed do to be replaced bare wires and such so i replaced all the cables even on the one on the emheat temp thingy...


model # ----make
n8msn091714a------heil gas unit
44860------- hunter thermostat
brhq030b---- coleman evcon heat pump

but if you look at my post with all the info about wires the colors really dont make any sence.

House--- Unit Wire/term---- EmHeat RElay box on side

RED---- RED /R
BLUE---- BLACK /C--------- (BLACK EMHEAT WIRE)
ORANGE ---ORANGE /O
GREEN ----GRAY /L--------- ( RED EMHEAT RELAY WIRE)
YELLOW ---YELLOW /Y
WHITE ---- STRIGHT TO EMHEAT RELAY----(WHITE EMHEAT RELAY WIRE)
BROWN---- WHITE /W2------- ( GREEN EMHEAT RELAY WIRE)

i think when it was wired the green was on the board to gas unit. and when the system sent a call to the "L" system i think is when it is killing my stuff... but i am not really sure i know it worked all 3 units when it was wired

in the instructions that you posted for your relay, it states that it is for use with electric back up, which you don't have!!! You need a dual fuel kit!!!
