Firestat Setpoint: This is the maximum temperature of the return air temperature
for the firestat alarm to occur and it cannot be disabled. A firestat alarm will cause
the unit to turn off until the alarm is no longer active. The range of adjustment is
100 to 150°F with a default setting of 150°F.
Hi Temp Alarm: When set to "Yes" (default) the alarm is enabled. When the return
air temperature rises above the set point, a high temp alarm will occur. During this
alarm, the fan will run at the maximum speed setting (plug fan only). The range of
set point adjustment is 70 to 90°F (70 to 120°F on CW units) with a default setting
of 80°F.
Lo Temp Alarm: When set to "Yes" (default) the alarm is enabled. When the
return air temperature drops below the set point, a low temp alarm will occur.
During this alarm, the fan will run at the maximum speed setting (plug fan only).
The range of set point adjustment is 70 to 55°F with a default setting of 60°F.
The rack sensor alarm screen will only appear if Rack Sensors are installed,
