During normal operation the Platinum Inlet/Tunnel curtain is connected through the RBU-27 SE PWR output (L1). In case
of a Platinum failure or in case the RBU-27 SE thermostat reaches the set point (Main Controller failure), the RBU-27 SE
takes control and cuts the PWR output to the Platinum and opens Inlet/Tunnel curtain. This feature prevents conflicting
commands between RBU-27 SE and Platinum.
NOTE: Other powered devices (for example heaters or fans) are powered normally.
