An air conditioning (HVAC) system for a residential dwelling or other building with enclosed spaces includes multiple thermostats hard wire interconnected or communicating via radio frequency transceivers. The thermostats each include control circuits for adjusting the setpoint temperature at any one thermostat and displaying the set temperature at all thermostats, setting the time at any one thermostat and displaying the time at all thermostats, controlling the thermostat temperature setting from a selected one of the thermostats and providing a setpoint for control of the air conditioning system based on an average temperature sensed by all of the thermostats. A method for correctly setting a thermostat time display to one of Daylight Saving Time or Standard Time and displaying an icon identifying one or the other is disclosed.
