* 8 WIRE INSTALLATION HEAT PUMP

I have a heat pump and have an 8 wire thermostat. I have searched and cannot find exactly how to install it. I have a red (connected to R), white (connected to WT), yellow (connected to Y1),  green (connected to G), orange (connected to O),  blue (connected to B) and a black and brown connected to another connector by themselves.

 

I would appreciate any help.

did you ever figure this out? I have similar issue- 8 wires with brown and black connected to S1 and S2. I can not find any answers anywhere. Thank you!

I just got a nest thermostat as a housewarming gift, also having this issue!
