Delta ControlsDocument Edition 4.1 Page 33 of 41If the application is something other than VAV or VVT, then both analog outputs may be configuredfor either heating or cooling. Analog outputs for heating or cooling may be either direct or reverseacting.For the HPU application, 2-position control is provided for the compressor and reversing valve, 0 or 10v(typically requiring an appropriate interface relay), rather than modulating the two analog outputs.OWS Functions1. DEVICE CONFIGURATIONThe BACstat can be configured and commissioned using the keypad buttons, via the ConfigurationMenu, without additional software. It can also be configured using the ORCAview OWS if the BACstatis connected to an MS/TP network.However, to do this requires a minimum configuration for each device to ensure they are all configuredthe same and are communicating properly on the designated network. These essential configurationitems include:• N ETWORK CONNECTION : LINKnet O FF (MS/TP).• DNA: O N or O FF• D EVICE ADDRESS: 1-99 for MS/TP• BAUD R ATE : Set the speed to match the network it will be connected to (76,800bps is the default)Configuration SettingsWhen the ORCAview OWS is able to access the BACstat and its objects, you may then configure thefollowing BACstat settings at the OWS (which are usually configured once and rarely ever changedthereafter). However, these must be configured in the sequence provided (which is the same as theConfiguration Menu). Any change to these settings from an OWS requires the BACstat to be reset(locally or via user command).• APPLICATION: AV12 (refer to page 12)• O UTPUT CONFIGURATION 1: AV21 (refer to page 28, and associated Applicationinformation)• O UTPUT CONFIGURATION 2: AV22 (refer to page 28, and associated Applicationinformation)• O UTPUT CONFIGURATION 3: AV23 (refer to page 28, and associated Applicationinformation)• ADDITIONAL P ARAMETERS: AV24 to AV29 (as per associated Application information)Control SettingsThese are other settings you may want to set from the OWS, which may also be commanded on the flyby a user or from a GCL+ program:• A LGORITHM M ODE : AV13 (which defaults to Night)• D AY SETPOINT: AV6• D AY M INIMUM : AV7• D AY M AXIMUM : AV8• D AY D IFFERENTIAL: AV9• N IGHT H EAT 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 thekeypad)
