Setpoint
Configure the setpoints to be used by the loop in different occupancy modes. Configure the 
minimum and maximum reset values to be used and the corresponding reset sensor values. 
Reset value to be added to the setpoint is calculated by the controller as a value between min max 
reset values in proportion to the reset sensor value.
Control Parameters Parameters that affect the output and the loop behavior can be configured. Below are the 
configurable parameters and its descriptions.
NOTE: If derivative time is set to zero, it disables derivative action.
NOTE: Modulating output threshold value for activating the Auxiliary output can be con-
figured to control the auxiliary output based on the value of PID loops modulating 
output.
Control Parameters
Configurable Parameters
Description
Throttling range
This is the proportional change in the sensed variable 
required to change the control output from 0 to 100 percent. 
This needs to be configured in the engineering unit of the 
main input sensor
Integral time
This determines the integral gain of the PID loop. The 
greater the time in seconds, the less the integral change per 
second. A setting of 0 eliminates the integral function.
Derivative time
Determines the derivative gain in a PID loop. The greater the 
time in seconds, the greater the derivative effect per second
PID action
Direct Acting or Reverse Acting selection determines the 
behavior of the loop output. In a direct acting control loop the 
output increases as the input sensor value rises above the 
setpoint. In a reverse acting control loop the output 
increases as the input falls below the setpoint.
Control Parameters Aux DO action
This determines the Aux DO behavior. The Aux output can 
be configured for either continuous or intermittent operation. 
This selection applies to occupied and standby modes only. 
Unoccupied is always intermittent. In continuous operation 
the output is continuous, regardless of the operation of the 
other outputs of the loop. In intermittent operation the output 
is on only when the modulating output of the loop is greater 
than 0 or at least one of the staged outputs is on.
Modulating control for Aux
This option allows the Aux DO to be controlled based on the 
value of the loops modulating output.
Modulating output threshold for Aux Modulating output threshold value for controlling the 
Auxiliary output. The Aux DO is activated if the PID 
modulating output is greater than the threshold value
Aux output minimum off time
The auxiliary digital output minimum off time.
NOTE: When staged outputs are configured this value 
must be configured to be less than (Cycler and 
stager interstage minimum on time - Aux output 
run on time).
Control Parameters Aux output run on time
The auxiliary digital output run-on time. A value of 0 disables 
the run-on time. This is typically used when the AuxDo is 
configured for intermittent operation.
For example, If the AuxDO is controlling the fan, this 
parameter can be used to keep the fan running for certain 
duration after the cooling or heating process has stopped.
Minimum off time
This is the minimum off time for the staged outputs
Cycler and stager interstage 
minimum on time
This is minimum amount of time a lower numbered stage 
must be on before the next stage can turn on.
Minimum on time
This is the minimum on time for the Aux DO and staged 
outputs
