12.5.4 Manual override board
The manual override board is located in the E box and is used for the manual control of components in the event
of a controller failure. With the help of this board, 4 digital outputs and 3 analog outputs can be operated manually.
If the A/C unit is equipped with a damper, a timer in the E-box ensures the delayed start of the fans, after the damper
is opened.
The image shows the board in the delivery condition, all toggle switches for the digital outputs are switched off.
The assignment of the outputs can be set customer-specifically and is documented in the E-plan.
The fan must run for 15 seconds, before the compressor may be switched on.
As soon as the controller is ready for use again, you must end the manual control by setting all toggle switches into
the "off" position.
