Description Description
Constant air volume with bypass damper manual reset value output.
This is the output when unit is off.
Supply static shutdown set point. Unit will shutdown for Parameter
110 minutes if duct pressure exceeds this value for 20 seconds.
•
The number of occurrences before permanent lockout. Counter
resets when M3 resets.
•
Refer to Parameter 226 to either enable or disable this feature.
•
Supply Static Pressure Sensor
(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.
Warm-up time delay. The time that the economizer is forced closed
during warm-up (first occupied + heat demand)
The time before the blower turns on after a electric heating demand.
The time the blower stays on after the heating demand is lost.
Service output activation. Maximum Primary and Secondary Limit
occurrences stored before service relay is energized.
Note: Heating stage is not locked out.
Time delay between heat stages.
•
Stage up timer. The maximum time that lower stage runs before
calling next heat stage. Used in room sensor applications.
•
Disabled if set to 0.
•
Time delay before a lower stage turns off following a higher stage
termination.
•
Used in room sensor applications.
Warm-up time delay. The time that the economizer is forced closed
during warm-up (first occupied + heat demand) .
The time before the blower turns on after a heating demand.
The time the blower stays on after the heating demand is terminated.
