I would question if the thermostat is accurate. Or very possibly, the thermostat is in a position that heated air flows across the thermostat, warming it before the rest of the air is adequately heated. Possibly redirecting the air flow or moving the thermostat might help.
the compressor does not run long enough to affect the thermostat..
Something is turning off the compressor...
coils may be icing up especially if it is near the dew point. once hey ice up either an electric element comes on to defrost them, or it will wait till the ice melts.
45F is a marginal temp for a heat pump especially if RH is much at all.
home heat pumps will switch over to all resistance heating once it gets cold enough and humid enough to have the efficiency drop to the same as resistance heating or less or if it ices up enough. Usually that's in the 30-40F range.
