11.5.3 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 oper-
ated 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 assignment of the outputs can be set customer-specifically and is documented in the E-plan.
End the manual control, as soon as the controller is ready for use again by setting all toggle switches into the
„off“ position.
