Abstract
A heating system and method of using such system in a building for zoned radiant heating. The system includes thermostatic radiator valves, each fluidly connected between at least one radiator in a zone of the building and a boiler. A controller is operatively connected to the valves to deactivate the valve positioners when the controller determines that valve activity is likely to have little to no effect on the output of the respective radiator and/or active heating of the building is not desired. For example, the controller determines when the boiler is deactivated and sends a deactivation control signal to the valves operative to prevent the valve positioners from adjusting the respective valve position. In another example, the controller sends the deactivation control signals to the valves at the onset of preprogrammed low usage periods of the heating system.
