Siemens BACnet VAV Actuator Owner's Manual
Description
The maximum temperature setpoint in degrees that
the controller can use from the setpoint dial. This
overrides any temperature setpoint from the
setpoint dial that falls above this maximum.
The temperature setpoint in degrees from the room
temperature sensor (not available on all
temperature sensor models). This setpoint will be
used for control in day mode (heating or cooling)
when enabled by STPT DIAL.
YES indicates that there is a room setpoint dial on
the room temperature sensor and it should be used
as the temperature setpoint for control in
day/occupied mode. NO indicates that the
appropriate preset setpoint will be used as the
temperature setpoint for control in day/occupied
heating or cooling mode. Valid input: YES or NO.
Actual reading from a 10K Ω thermistor connected
to the controller's Al 3 input. When a thermistor is
connected at Al 3, DI 3 is not available. See DI 3.
Actual reading from a 10K Ω thermistor connected
to the controller's Al 3 input. The controller uses this
value to determine whether it is in heating or
cooling mode.
Determines how the damper modulation will be
sequenced while in heating mode. When HTG
LOOPOUT is above this value, then FLOW STPT
starts to increase.
Determines how the damper modulation will be
sequenced while in heating mode. When HTG
LOOPOUT is below this value, then FLOW STPT
starts to decrease.
YES indicates that the controller is to monitor the
status of a wall switch that is connected to DI 2. NO
indicates that the controller will not monitor the
status of a wall switch, even if one is connected.
Valid input: YES or NO.
Actual indication of the status of the override switch
(not physically available on all temperature sensor
models) at the room temperature sensor. ON
indicates that the switch is being pressed. OFF
indicates that the switch is released.
Valid input: ON or OFF.
The amount of time in hours that the controller will
operate in day/occupied mode when the override
switch is pressed while the controller is in
night/unoccupied mode.
