Output Parameters Default
Manual Access Parameters
The FB provides all the functionalities the operator needs to interact with the loop.
The loop is controlled by one PID, connected internally to a Auto Manual block (the
Split Range version) which provides auto/manual/track/aux operating mode. These
modes, that are unique for both the Cool and the Heat output, are defined by a set of
digital inputs, as listed above, ordered according to their priority level.
Trk DTRK
AutoMan DAM
Aux DAUX
Depending on these digital inputs, the functionality of the module changes as follows:
• If none of these digital signals are active, the FB does not alter the control
output signals. The
DEADBAND parameter defines how the Cool and the
Heat channel interact each other. When it is positive, this parameter
defines the dead band width, centered on the value 0 of the output. It
means that for each output value included in the dead band both the
OUTH
and the OUTC output are 0. When it is negative, the opposite occurs; for
each value included in the deadband (now named cross band), both the
OUTH and the OUTC are different from 0.
