the Duty Cycle setting. The Lead output will continue to cycle On and Off, however, the additional outputs will
remain activated with 100% duty cycle until the setpoint deadband is satisfied.

ther an On or Off Delay Time setting specified, the delay will be managed for the Lead output only. If one or
more Lag outputs provide Backup or Wear Leveling support, the Delay Times would also effect these outputs.
However, if additional Lag Output(s) are energized due to Activation Mode settings, the additional outputs will
operate independently of the On or Off Delay Time setting(s) and will energize and de-energize without delay
when needed.

5.3.21
Analog Output, Proportional Control Mode
Output Details
The details for this type of output include the output %, HOA mode or Interlock status, accumulated on-time,
alarms related to this output, current cycle on time, relay type and the current control mode setting.
Settings
Touch the Settings icon to view or change the settings related to the relay.
Set point
Enter the sensor process value at which the output % will be the programmed minimum %.
Proportional Band
Enter the sensor process value away from the set point at which the output % will be
the programmed maximum %.
Minimum Output
Enter the lowest output %. If the output should be off at the set point, this will be 0%.
Maximum Output
Enter the highest output %.
Hand Output
Enter the output % desired when the output is in Hand mode.
Off Mode Output
Enter the output mA value desired when the output is in Off mode, or being Interlocked, or
during a calibration of the sensor being used as an input. The acceptable range is 0 to 21 mA.

Enter the output mA desired when the sensor is not giving the controller a valid signal.
The acceptable range is 0 to 21 mA.
Input
Select the sensor input to use for proportional control.
Direction
Select the control direction.

Analog or Relay Output, PID Control Mode
ONLY AVAILABLE IF CONTROLLER INCLUDES PULSE OUTPUT OR ANALOG OUTPUT HARDWARE &
HVAC MODE IS DISABLED
The PID algorithm controls an analog output using standard Proportional-Integral-Derivative control logic. The
algorithm provides feedback control based on an error value continuously calculated as the difference between a
measured process variable and a desired set point. Tuning settings specify the response for proportional (the size of
