Table 6.1 Parameter Groups
Parameter descriptions and selections are displayed on the
graphic (GLCP) or numeric (NLCP) display. (See the relevant
section for details.) Access the parameters by pressing
[Quick Menu] or [Main Menu] on the LCP. 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 most HVAC applications but if other
special functions are required, they must be programmed
as explained in parameter group 5-** Digital In/out or 6-**
Analog In/out.
