How do I stop a commercial airhandling unit of the ProNordic type?
To stop a commercial airhandling unit of the ProNordic type, access the control panel and select the menu “service switch”. Then choose the command “OFF”.
Please note that in some cases the unit may continue running for up to 180 seconds before it stops completely. This is a normal function and is designed to allow the heating coil to cool down before full shutdown.
