See above.
HVAC_OFF
This output variable is used to coordinate the slave devices with
(at application restart)
the master controller. It reflects the current heat/cool medium
based upon the available supply energy. This is required for con-
figurations with heat/cool changeover. HVAC_OFF switches the
heat/cool control OFF while still providing frost protection and
reporting status and alarms.
This output variable is the cooling output which is typically used for
monitoring or bound to a cooling actuator node or another con-
troller operating as slave. nvoCoolOutput will be transmitted
immediately when its value has changed significantly (>= 1%), and
periodically according to nciSndHrtBt. The output value represents
the output of the control algorithm but is limited to a range of 0% to
100%.
This output variable indicates the binary state of the controller's
digital input which can be configured to support a window contact,
an occupancy/movement sensor, an air flow contact, or a heat/cool
changeover contact. It can be bound to another Excel 10 controller
or a third party node.
See above.
This output variable reflects the effective occupancy mode derived
from the time schedule, occupancy sensor, override button, and
network occupancy override.
0 (at application restart)
This output variable reports the fan speed for the controller. It can
be bound to another Excel 10 controller with a fan connected or to
a third-party fan node.
NO_FAN
See above.
