New RTH6360 not heating
I picked up the above mentioned thermostat when I saw a deal on it, because I've really wanted a programmable thermostat, but it appears I mixed something up somewhere.
The pictures below are of the old and new wiring. The color coding might be off a bit, the wiring from an old unit was reused, I believe.

In the old picture, it's hard to tell, but R and Rc are jumped using what looks like a staple.

The heating unit is a Rheem model RQNJ-A036JK.
I tried most of the option combinations, but the last one was:
Heating system type: 2 Heat pump
Heating equipment type: 7 Air to air heat pump
Reversing valve O/B: 0 O/B in cool
Cooling stages: 1
Heating stages: 1
Any help you can provide would be tremendosly appreciated.

Rheem, unlike most other manufacturers, powers the reversing valve to heat. The O/B should be set to "B" (energize to heat). It also appears that you have 2 stages of heat & one of cool.
Use a volt meter set for AC volts to check for 24-28 volts between the red & black wires.

Your wiring looks OK. Try configuring the stat as I suggest in the previous post. I think you can install batteries & configure the stat before mounting it to the base.

These should be your settings. The thermostat will eventually bring on the AUX heat but it may not be as soon as you increase the thermostat. Have not found a RTH6379D in the list.
200 = 2 (heat pump)
205 = 7 (air to air heat pump)
218 = 1 (O/B in heat mode) This is the correct setting for Rheem/Ruud systems
220 = 1 (cool stage)
221 = 1 (heat stage) 1 (backup heat stage)
