3.2.3.8.桠 Reset F/H/M
This option is used to reset the filter hour meter. The filter hour meter indicates how long the filter has been in
operation. Maximum counter is set at 10,000 hours (100%). The counter value can be checked while in the
diagnostic mode. Please reset the filter hour meter after each filter replacement.
3.2.3.9.桠 Reset Default
User can reset default settings by choosing this option. The features being reset are warm up period (3
minutes), post-purge period (0 minute), UV timer (60 minutes) if present, measurement unit (metric), airflow
monitor (enabled), ADMIN PIN (0009), filter life display (disabled) and FAN PIN (0000).
Note that the calibration settings cannot be reset as it may cause the BSC to operate in an unsafe manner. The
hour meters cannot be reset using this function either.
3.2.3.10.桠 Airflow Out Temp
Using this option, the user can select whether or not to display the airflow when the ambient temperature is
out of the optimum temperature range, below 18
3.2.3.11.桠 Set Sash Cycle (Not applicable to non-motorized sash BSC)
To reset the sash cycles count to zero or to input the sash cycle count manually. The maximum value of sash
cycles is 16,000 and after which the motor needs to be replaced (e.g. as part of the preventive maintenance
program). The cycles will raise every sash move to up and down.
Warning message will be shown after the cycle value reaches 15,000.
桠 † 1st warning: "Replace Sash Motor" – after sash reached 15,000 cycles.
桠 † 2nd warning: "Stop Using Sash" - after sash reached 15,500 cycles.
桠 † 3rd warning: "Sash Motor Locked" (sash motor cannot operate) - after sash reached 16,000 cycles.
3.3.桠 Alarms and Warnings
A BSC uses alarms to indicate that the condition inside the BSC is not safe for the operator, so check the LCD
display to understand the cause of these alarms. The most common alarm is the SASH ALARM, which indicates
that the sash is neither at the normal operating height nor at fully closed position (UV mode) – this condition
can easily be corrected by putting the sash at the appropriate operation position.
Other alarms that indicate a failure or an error in the BSC system:
桠 † AirFlow: NO! will be displayed if there is an airflow failure.
桠 † SASH: ERROR POSITION indicates a failure in the sash detection system.
桠 † SENSOR UNCALIBRATED will be displayed if the airflow velocity sensor is not yet calibrated
桠 † Warning: Low Inflow will be displayed if inflow velocity is less than minimum inflow.
桠 † Warning: Low Downflow will be displayed if downflow velocity is less than minimum downflow.
桠 † Warning: High Downflow will be displayed if downflow velocity is higher than the maximum
downflow.
桠 † Watchdog failure will be displayed if there is communication failure between the mainboard and
watchdog board.
桠 † DAC failure will be displayed if there is communication failure between the mainboard and DAC.
