In units with built in electrical heater the heating rods are located after the supply air fan in the airflow direction. The
material is stainless steel. The electric heating coil has both automatic and manual overheating protection. The manual
overheat protection is reset by pushing the red button on the side of the electrical heater frame by the use of a pointed
tool (figure 3). The power demand of the electric heating coil is controlled by the main regulator, which controls the
heat according to the desired supply/extract or room air temperature that is set in the control panel.
