Miscellaneous Configures operator bypass and priority
options.
Bypass Time
Define the period of time (0 to 1080 minutes)
in which the controller operates to occupied
setpoints after the local user has pressed the
override button.
Override Priority
Allocate priority between local wall module
operations (for example, Bypass) and
commands from the building management
central. Choices are:
Last Wins
- Last received input takes
precedence. It can be either the Bypass
button or the Network signal.
Network Wins
- The Network signal
always takes precedence over the Bypass
button.
Energy
Management
DLC SetPoint Bump
For load shedding applications. Define the
temporary setpoint shift to be added to the
setpoint when the controller receives a Load
Shedding command. By raising the setpoint
during cooling operation, or reducing the
setpoint during heating operation, the
controller reduces the amount of heat or cool
energy dissipated as a contribution to load
shed algorithms.
