Stc1000 issue

Systems, Gear, & DIY

So I built the stc1000 for my term chamber as per several you tube builds, verified all wiring, etc. I only have the outlet for cooling plugged in and when the temp is above pre-set everything kicks on fine. My issue is if the temp goes below are set the unit switches to heat but activates the cooling outlet and the compressor kicks on and chills.

Do I need to have a heat source plugged in as well or is something not right. I thought without having a heat source plugged in the unit would simply sit idle

Confused

Did you break the hot tab between the two sockets on the outlet?
