I woke up this morning with my thermostat set on 74 (cooling) and although the unit was running, the thermostat said 78 and the air was not cool coming from the vents. No error codes, no flashing lights and NO WATER PUMPING from the return. I immediately turned the system off, I have not turned it back on. Does anyone have any advise on this.

No water pumping from the return.....what does that mean? Water out at the heat pump? Likely your water flow is interrupted, either the well pump does not run, or the valve allowing flow is not opening. More details are needed.
