OWS Functions
1. D
EVICE CONFIGURATION
Although the BACstat was designed to be configured and commissioned using the keypad buttons right at the
device without any additional software (via the Configuration Menu), it may also be configured using the
ORCAview OWS, assuming the BACstat is connected to an MS/TP network (and not LINKnet).
However, to do this requires a minimum configuration for each device to ensure they are all configured the same
and are communicating properly on the designated network. These essential configuration items include:
• N
ETWORK CONNECTION: LINKnet ON or OFF (i.e., LINKnet or MS/TP). Do not mismatch
MS/TP and LINKnet devices on the same network.
• DNA: O
N or OFF (only applicable when connected to MS/TP)
• D
EVICE ADDRESS: 1-99 for MS/TP (assuming DNA is turned ON) or 1-12 for LINKnet
• B
AUD RATE: Set the speed to match the network it will be connected to (76,800 bps is the default)
As the temperature units (
ºC or ºF) can only be set via the Configuration Menu at the device (particularly when
connected to LINKnet), you may want to set this at the same time.
Configuration Settings
When the ORCAview OWS is able to access the BACstat and its objects, you may then configure the following
BACstat settings at the OWS (which are usually configured once and rarely ever changed thereafter). Note
however that these must be configured in the sequence provided (which is the same as the Configuration Menu).
Also, any change to these settings from an OWS requires the BACstat to be reset (locally or via user command).

Control Settings
These are other settings you may want to set from the OWS, which may also be commanded on-the-fly by a user
or from a GCL program:
• A
LGORITHM MODE: AV13 (which defaults to Night)
• D
AY SETPOINT: AV6
• D
AY MINIMUM: AV7

AY MAXIMUM: AV8
• D
AY DIFFERENTIAL: AV9
• N
IGHT HEAT SETPOINT: AV10 (which can only be changed remotely, not via the keypad)
• N
IGHT COOL SETPOINT: AV11 (which can only be changed remotely, not via the keypad)
Additional Settings
These are additional settings you may also want to set from the OWS, and may be commanded as necessary, but
rarely are once they have been set (or the control loop has been tuned).
