Default Heating mode -Compressor not coming on

I have a Bryant Zone Perfect Plus system. I just tried to turn the heat on for the first time since moving into house I purchased.

First of all the system is working fine in cooling mode. When I switch to heating the condensers compressor and fan do not come on. The fan inside the house stays on but just blows out neutral air.

Does anyone have an idea as to what could be causing the compressor to not come on.

While there are many things that could be causing this problem, I would start with troubleshooting the thermostat. Make sure it is 'heat pump' compatible and is wired correctly. From there, you will need to get out your volt/ohm meter and start checking for voltage on the reversing valve and compressor contactor.
