IDLE SCREEN: When the controller is idle for 10 minutes, the screen will revert to an idle screen that displays the control status and temperatures in large graphics and fonts so that it can be read from a short distance. Screen will also darken slightly after 1 minute of no activity. Simply touch screen anywhere to bring brightness back up. Press MENU button to access MAIN screen. If controller is passcode protected, pressing the MENU button will launch screen requesting passcode. Items on the IDLE screen that are adjustable are MANUAL SET POINT and the MINIMUM SPEED of STAGE 1. ================================================================== 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 .
