The electronic panel heaters feature highly accurate electronic thermostats
(+/-0.3°C), providing superior comfort and operating efficiency.
As the room temperature nears the desired set point, power to the
elements is reduced. The room temperature is closely monitored to an
accuracy of less than 0.3°C, minimising overshoot and temperature drift,
resulting in better energy efficiency and user comfort.
