HVAC Products 6 Temperature or pressure controller (internal load controller LC) 01.10.2003
BACS as control via analog input with the internal load controller.
In principle, identical to operating mode 3, except that the BACS delivers the predefined
setpoint via analog input 3 (SET POINT INPUT).
Terminals X62.1 and X62.2 can be used to make a changeover from externally (e.g. in
the event the BACS fails) from the external predefined setpoints to the internal setpoint
W1, using a potential-free contact (LC software version V01.40 or higher).
With a predefined setpoint via DC 0...10 V signal, voltage – in the case of changeover
to the internal setpoint «W1» - must be separated from input X62.2.
