Configuring alarm silencing
Alarm silencing is the amount of time an alarm is temporarily disabled (silenced) after it has been
acknowledged. Alarm silencing prevents the alarm relay from triggering immediately if it has been
acknowledged when the alarm condition is still present. If the alarm condition is still present after the
silencing duration, the alarm triggers again.
Default: 15 minutes Range: 1 to 240 minutes (4 hours)

Configuring the zone control mode
There are two zone control modes: staged and merged.
Staged mode
Staged mode is the traditional ventilation mode that uses “stages” of variable and/or fixed stage equipment.
As the temperature increases, stages increase speed or switch on in sequence to increase ventilation and cool
the room.
Staged mode uses a master set point and individual equipment set points. A master set point is the desired
or target temperature for a zone. When you adjust the master set point, the equipment set points are
automatically adjusted by the same amount.
You can use a growth curve and/or a minimum ventilation curve in staged mode.
Merged mode
Merged mode uses steps. Each step has a temperature range and an output range for the equipment that
operates during the step. As the temperature increases, ventilation equipment increases speed, switches on,
or opens to increase ventilation and cool the room. One of the benefits of merged mode is that it can
provide smoother transitions between steps than staged mode can between stages.
Merged mode can have up to 10 steps. Each step has a temperature range and an output range for the
equipment that operates during the step.
You can use a growth curve in merged mode, but you cannot use a minimum ventilation
curve.
