Methods and systems for controlling temperatures in plasma processing chamber for a wide range of setpoint temperatures and reduced energy consumption. Temperature control is coordinated between a coolant liquid loop and a heat source by a control algorithm implemented by the plasma processing module controller. The control algorithm may completely stop the flow of coolant liquid to a temperature-controlled component in response to a feedback signal indicating an actual temperature is below the setpoint temperature. The control algorithm may further be based at least in part on a feedforward control signal derived from a plasma power or change in plasma power input into the processing chamber during process recipe execution.
