When we first tried our coach out I wondered why the floor and drawers were always warm. The Comfort Control was off so was not calling for heat. After downloading the service manual I discovered the bypass pump switch on the distribution module had been left on so was circulating hot fluid all the time. This is only used by service personnel to do the initial fill and purge air out of the system. Turning that off fixed my problem.
