9.3.4 Setpoints
The following applies to controller 2, basic type A, and controllers 1+2, basic type
U:
You can assign individual setpoints for the Comfort and Economy modes.
•
We distinguish between the following setpoints:
•
SET MIN lower setpoint "Heating" (sequence 1+2)
–
SET MAX upper setpoint "Cooling" (sequence 4+5)
–
These functions can have an influence on the setpoints:
Universal setpoint shift
•
Remote setpoint, absolute
•
9.3.5 Troubleshooting
Incorrect configuration has the following effect:
Configuration point
Main controlled variable (MAIN)
dDifferential input (DIFF)
Main controlled variable (MAIN)
Differential input (DIFF)
When you leave the commissioning menu, the universal controller checks whether
a main sensor is connected.
If, at that time, the main sensor is connected, but is missing later, or if there is a
•
short-circuit in the cable, a sensor error message is delivered and shown on the
display:
"Xx ---" => main sensor missing
–
"Xx ooo" => short-circuit
–
If, at that time, there is no main sensor (main controlled variable in this case),
•
the plant will be shut down (MAINALM)
