Offset adjustment is for minor variations in probes and not intended to correct the reading of a faulty probe. 21A 21B
Hog Slat Inc. Newton Grove, NC USA May 2024 REV IR 24 Ventilation System ================================================================== 22. CURVES: The temperature SET POINT comes from one of two locations. One location is the manually adjusted value on the MAIN screen or IDLE screen, the second is from a temperature curve which defines the set point based on a day number. The temperature curve is defined by 6 data entries. Each define the day number, temperature and minimum speed ventilation. Temperature set point will decrease proportionally every hour between the set points automatically when the temperature curve is activated. Once the final day entry is reached, the controller will hold that temperature until the temperature curve is re-activated. Rules for entries Highest day entry 999 First day entry must start at the lowest day number. Day number entries must always increase for each of the following data row entries. Typically the highest temperature will be on the first day entry (first row of data) and decrease. However note the temperature entries can increase or decrease. Maximum deviation in temperature between day entries is 4F (2.2C) Minimum ventilation curve follows the same day number as the temperature curve and is active simultaneously with the temperature curve. Minimum ventilation curve sets the minimum speed of the Stage 1 fan for each day entry. 22A: TEMPERATURE/DAY CURVE INPUTS: Press the block for the day entry# or the temperature entry#.

Hog Slat Inc. Newton Grove, NC USA May 2024 REV IR 27 Ventilation System ================================================================== SECTION 11: PC Interface: The HSVC1024 series controller is capable of interfacing with a PC interface controller using a HSVC-PCCOM2 communication card installed in the HSVC1024 controller. This allows the ventilation controller to communicate information to the PC interface such as set point, temperatures and alarms. Also allows the PC interface to control the set point, alarm reset and cleaning modes. When the PC Interface performs an initial search of controllers connected, it will assign each ventilation controller a unique number (see below figure showing the location of the Controller ID#). The set point and room temperature is communicated from the ventilation controller to the PC Interface. The PC Interface can also change the set point of the ventilation controller. When the PC Interface places the ventilation controller in “Cleaning Mode” the ventilation controller will follow the cleaning mode set point established by the PC Interface, switch to minimum ventilation and an ICON will pop up on the IDLE and HOME screens indicating the controller is in Cleaning Mode. Once controller is taken out of “Cleaning Mode” the set point will have to be changed from the Cleaning Mode set point as required at the ventilation controller or the PC interface . SECTION 12: IMPORTING AND EXPORTING DATA To import or export SETTINGS, access data port by opening front door. Access the USB data port located on the back of the front door near the bottom of the circuit board. Insert flash drive provided with controller. A USB style plug icon will appear on the screen. On the SETTINGS SCREEN press IMPORT / EXPORT SETTINGS. Controller ID #
Hog Slat Inc. Newton Grove, NC USA May 2024 REV IR 28 Ventilation System Follow on-screen instructions which will allow user to acknowledge importing or exporting to the flash drive. EXPORT is when you wish to save the controller settings to the portable flash drive. IMPORT is when you wish to save the portable flash drive data to the controller. This will overwrite any existing settings in the controller and replace them with the data from the flash drive. Once process is complete, the USB style icon will flash. If error occurs during the process, an error screen will appear. If this occurs, remove flash drive and wait 10 seconds and re-insert and restart process. SECTION 13: FACTORY RESET In the event it is desired to return the controller back to factory default settings, a FACTORY RESET can be performed. Go to SETTINGS PAGE and find the ICON “FACTORY RESET.” Press the icon and a new page will be launched for you to confirm the factory reset. Press “YES” for at least 2 seconds and controller will be returned to its factory state. SECTION 14: BATTERY BACK UP Settings in the controller are backed up with an onboard battery for extended data retention after power loss. However the controller also provides input terminals for user to connect a 12VDC battery to provide backup operation during power loss. DC back up voltage will allow operation of Stage 3 through 6 only. See wiring diagram for battery connection location. Battery not included. SECTION 15: SOFTWARE UPDATE In the event it becomes necessary to update the microprocessor software, it can be updated via the data port. Remove power from the controller. Access the data port located on the back of the front door near the bottom of the printed circuit board. Insert flash drive containing software update. Return power to controller. Update should start automatically. Screen visible will show V1.5 with an increasing numeric value beside it indicating the status of the update. Once the update completes the display will indicate to remove the flash drive. In the event the automatic update does not start on power up, remove power and start process once again. Touchscreen display can also be updated. This information contains all of the on-screen information and touch panel configuration. Remove power from the controller. Open front door and locate the SD card slot that is found on the right side of the circuit board. Use the SD card containing the software update. Insert SD card until it clicks into place. Restore power to controller. Automatic update will occur. When complete, screen will switch to HOG SLAT LOGO/GROWER SELECT screen. In most cases controller will resume operation from this screen, If not, touch the screen twice which will advance screen to the MAIN screen. UPDATE is complete. Remove power and remove SD card by pushing in the card to release it.
