Building Technologies Configuration 01.02.2010
Parameter Range Function
Cooling 2 pump No No additional water cooling pump.
Yes Water cooling pump without pump kick. Digital output for the pump.
Yes+Kick Water cooling pump with pump kick. A digital output for pump and ac-
tivation of pump kick.
Pump kick: Pump is switched on for a short period after idling for a
longer period. This prevents lock up.
Cooling 2 pump alm No Pump without alarm or feedback.
Alarm Pump with alarm. Digital input for pump alarm. Logical 1 = alarm, im-
mediately shuts down the pump.
Fdbk Pump with feedback. Digital input for feedback (logical 1 = Pump running).
Both Pump with alarm and feedback. Two digital inputs for pump alarm and
feedback.
Cooling 2 Dx alarm No Additional direct expansion evaporator without alarm or feedback.
Alarm Direct expansion evaporator with alarm. Digital input for pump alarm.
Logical 1 = alarm, immediately shuts down the pump.
Fdbk Direct expansion evaporator with feedback. Digital input for feedback
is enabled (logical 1 = Pump running).
Both Direct expansion evaporator with alarm and feedback. Two digital in-
puts for alarm and feedback.
Cooling 2 control Positioning of additional cooling register.
StandAlone Cooling register not integrated in sequence. An additional analog input for
one control sensor (if not already enabled for Heating 2 or El Heating 2).
InSequence e.g. integrated as second cooling register in the sequence.
Fire damper fdbk Fire damper feedback.
Closed Only one feedback for close. Digital input.
Clsd+Opnd Two separate feedbacks for open and close. Two digital inputs.
Combined Two feedbacks for open and close, but only one signal. The syntax
must be correct 1->0->1 => Close-> Movement -> Open. Digital input.
Auxiliary input No No auxiliary input.
Input An additional digital input for display only.
Alm An additional digital input with alarm.
Inp+Alm Two additional digital inputs. One for display and one with alarm.
Aux tmp sensor No No additional analog input.
Yes Additional analog input to connect a temperature for display.
Aux TSP output No No additional digital output.
Yes An auxiliary digital output controller by its own time switch program.
Aux A outp fan No No additional analog output.
Yes Auxiliary analog output that provides a 0-10 V signal depending on the
present fan step.
Aux op mode
indicat
No No additional digital output.
Yes An additional digital output, switched dependent on present operating
mode (e.g. Comfort or Off).
Configuration 2 This parameters enable the plant after successful parameterization.
Enable occurs when Configuration 1, Configuration 2 and Configura-
tion IOs are completed, i.e. when each has the value "done".
NotDone Plant locked against switching on.
Done The plant is unlocked after complete parameterization (Configuration
2 and Configuration I/Os also have a value "done"), i.e. it can be
switched on.
Needed Required !! Passive
Execute
Reset required after successful parameterization in Configuration 2.
Assumes the appropriate presettings for Configuration I/Os.
After reset, value automatically goes from execute to passive.
