Wiring Honeywell RTH3100C thermostat

I replaced my old mechanical thermostat with a Honeywell RTH3100C digital. My heatpump is an older Rheem. My wires are RED,YELLOW,GREEN, WHITE AND WHITE1. I connected the red,green,yellow to their respective terminals. I don't know what to do with the White1. The blower comes on and with the White 1 connected to the B terminal the aux heat comes on but the compressor doesn't run.

I know there have been several questions on this thermostat on this site but none of them seem to be the fix I need.

Thank you, Jerry
