8.2.1 Sync Outputs with Active Blower
Sync outputs with active blower allows for the listed functions to be turned on and off automatically when the
blower is actively running. If the blower is pending (blinking LED above blower switch), these listed functions will not
turn on if selected as active. ONLY when the blower is actively running will these functions turn on.
Fan Relay – Normally the fan relay will activate when the blower switch is pressed. Blower can
either be actively running or pending. If the fan relay sync is active the blower
must be actively running for the relay to change state.
Fluorescent Light – Normally the fluorescent light is turned on via the fluorescent light key. If the
fluorescent light sync is active; the blower must be actively running for the fluorescent
light to turn on.
15Volt DC Output – Normally the 15 Volt DC output located on the control board is on when power is
applied to the FlowGard™ system. If the 15 volt DC output is active, the blower must
be actively running for the 15 volt DC output to turn on.
Accessory Outlet – Normally the accessory outlet is on all the time. If the accessory outlet sync is active,
the blower must be actively running for the accessary outlet to turn on.
Outlet Power – Normally the outlet power is turned on via the outlet key. If the outlet power sync is
active, the blower must be actively running for the outlet power to turn on.
8.2.2 Function Options
Disable Intelliflow – If this function is active. All airflow display and alarm functions are turned off.
Allow UV light anytime – Normally the UV light is interlocked with the window being in the closed position. For
service purposes only, if this function is active, the UV light may be turned on at any
window height.
Note:
IN addition to the Allow UV light anytime system function, there is a double redundant
UV light window interlock relay. To override the UV light window interlock relay, the
relay itself must also be shorted (see electrical schematic for reference).
Alarm Active in Warm Up – Normally the audible and visual alarm is not active during the blower warm up period.
If this function is active, both an audible and visual alarm will occur during the blower
warm up period. The audible alarm may be silenced, but the visual alarm will remain
active until the warm up period is complete.
Airflow Alarm Silence – Normally airflow alarms that occur can be temporarily silenced (i.e. default audible
silence time is 15 minutes) by pressing the alarm silence key. If this function is turned
off, the audible alarm cannot be silenced.
