Common Operations
The Excel 10 W7750 Controller applications have many
common operations that are applicable regardless of the type
of heating, cooling, or economizer equipment configuration.
These operations are available to the W7750A and the
W7750B,C Versions of the CVAHU Controller, and the I/O and
network configurations for them are summarized in Table 14.

These operations are available to the W7750A and the
W7750B,C Versions of the CVAHU Controller, and the I/O and
network configurations for them are summarized in Table 14.
Available input options are from the wall module and the
hard-wired analog and digital inputs. Each application can
have only a subset of these devices configured based on the
number of physical I/O points available. However, some of the
inputs are available over the L

controlling the supply fan. In addition, if modulating
economizer control is desired, a discharge air
temperature sensor must be physically connected to
the Excel 10 W7750 Controller. A discharge
temperature signal cannot be brought into the
controller through the L
