IEC/TC 72 is responsible for standards covering automatic electrical controls for use in, or on, heating and air conditioning equipment and components. Twenty attendees representing Canada, Denmark, Italy, Germany, the Netherlands, Switzerland, the U.K., and the U.S. were in attendance.

The working groups developed proposed revisions to the standards for Automatic Electrical Controls, IEC 60730-1, part 1 general requirements and several of the part 2 standards, including specific standards for temperature and pressure sensing, burner controls, timers, thermal motor protectors, actuators, and more. These standards address electrical and electronics safety as well as safe software used in controls. The part 1 standard and most of the part 2 standards have either been adopted or adapted for use in North America in parallel with legacy standards covering the same product. Those legacy standards will be phased out over time.
