41 BLOWER MANUAL RESET
Constant Air Volume with
Bypass Damper Manual Reset
Value Output Percentage
Setpoint
20.0 52.0 100.0 %
Constant air volume with bypass damper manual reset value output.
This is the output when unit is off.
42 STATIC SHUTDOWN SP
Air Supply Static Shutdown
Setpoint
0 2 5 w.c.
Supply static shutdown set point. Unit will shutdown for Parameter
110 minutes if duct pressure exceeds this value for 20 seconds.
43 STATIC LOCKOUT CNT
Static Pressure Lockout
Counter Setpoint
1 3 7 Counts
The number of occurrences before permanent lockout. Counter
resets when M3 resets.
Refer to Parameter 226 to either enable or disable this feature.
44 STATIC LO ALARM CHK
Supply Static Sensor (A30) Low
Alarm Percentage Setpoint
30.0 40.0 100.0 %
Supply Static Pressure Sensor (A30) connected at
(A133_P195_6) (TB18_6) alarm threshold.
Blower percent speed before checking sensor after a 20 second
delay.
A value of 30% disables the low threshold or “open" alarm trap.
