99 Dutchmen with DuoTherm clicking

I know this has been discussed -- lots of clicking up in the AC unit as the furnace cycles on and off. As far as I can see with a non-digital setup like this '99 model there is no way to set it to drop a few degrees below the target temp before turning on and and running until a few degrees above the desired temp.
If its normal I'll live with it, but just want to make sure it isn't a relay getting ready to fail.

We're living in this Fifth Wheel until our house is finished in December -- NW Washington -- so prefer to head off problems in advance, especially heating.
