I don't know what rods etc. may be missing from between your Pines Winterfront thermostat and your radiator shutters. However, if your Pines Winterfront thermostat turns out not to function or functions improperly consider utilizing the services of Jim Otto, a retired engineer who worked for the company that originally built the units. He can rebuild and/or recalibrate the unit for you. I have found his work to be exemplary and reasonable in cost. His telephone number is 865-966-9494. Tell him Ed Miller referred you to him. Good luck.
