Order:
Configuration
procedure
• Basic configuration (APPL ID) first, then extra configuration (CONFIG)
• First the input identifiers (LABEL), then the control functions, then the
aggregates
Wiring choices:
• Always from the arrow to the line
• From function to input: "x" to "x"
• From output block to output terminal: Analog "Y" to "Y"
• Relay "Q" to "Q"
• From the controller: Load "y" to "y", pumps "p" to "p"
The following applies to outputs:
Use of outputs Yx
• Connect the output functions to the respective terminals. Each output terminal
can only be used once (e.g. Q1 for pump 1)
• Each output function has no more than 2 load signal inputs with maximum
selection. Example: The air cooling coil valve opens if the room temperature or
room air humidity is too high
