23- Time Based Functions
24- Application Functions 2
25- CascadePack Controller
26- Analog I/O Option MCB 109 Parameters used to configure the Analog I/O option (MCB109) including: definition of the analog input
Parameter descriptions and selections are displayed on the graphic (GLCP) or numeric (NLCP) display. (See relevant section for details.) Access the
parameters by pressing the [Quick Menu] or [Main Menu] button on the control panel. The Quick Menu is used primarily for commissioning the unit at
start-up by providing the parameters necessary to start operation. The Main Menu provides access to all parameters for detailed application programming.
All digital input/output and analog input/output terminals are multifunctional. All terminals have factory default functions suitable for the majority of HVAC
applications but if other special functions are required, they must be programmed as explained in parameter group 5 or 6.
Time based parameters including: those used to initiate daily or weekly actions based on the built in real
time clock (e.g. change of setpoint for night set back mode or start/stop of the pump/fan/compressor
start/stop of a external equipment); preventative maintenance functions which can be based on running
or operating hour time intervals or on specific dates and times; energy log (especially useful in retrofit
applications or where information of the actual historical load (kW) on the pump/fan/compressor is of
interest); trending (especially useful in retrofit or other applications where there is an interest to log
operating power, current, frequency or speed of the pump/fan/compressor for analysis and a payback
counter.
Parameters used to set-up Fire Mode and/or to control a bypass contactor/starter if designed into the
system.
Parameters used to configure and monitor the built in pump cascadepack controller (typically used for
pump booster sets).
types (e.g. voltage, Pt1000 or Ni1000) and scaling and definition of the analog output functions and
scaling.
