HYD Miscellaneous Parameters
Purpose
To configure miscellaneous and energy management 
parameters.
Mode
Configuration can be performed with the wizard Off-line or 
On-line. 
Procedure
1. Click the Miscellaneous button on the left pane to open 
the Miscellaneous Configuration page.
2. Enter information into available fields. 
3. Click Commit to save the settings or Reset to revert to 
the last saved settings. 
4. Click Next to display the PID Configuration page or 
Back to display the Zone Control Configuration page.

HYD PID
Purpose
To configure the variables for closed loop control. PID 
parameters can be set separately for both heating and cooling 
control.
Mode
Configuration can be performed with the wizard Off-line or 
On-line. 
Procedure
1. Click the PID button on the left pane to open the PID 
Configuration page. 
2. Enter information into available fields (see Table 47 on 
3. Click Commit to save the settings or Reset to revert to 
the last saved settings. 
4. Click Next to display the Wiring Configuration page or 
Back to display the Miscellaneous Configuration 
page.

Miscellaneous Configures operator bypass and priority options.
Bypass Time
Define the period of time (0 to 1080 minutes) in which the controller operates to occupied setpoints after the 
local user has pressed the override button.
Override Priority
Allocate priority between local wall module operations (for example, Bypass) and commands from the building 
management central. Choices are:
LAST WINS – Last received input takes precedence. It can be either the Bypass button or the Network 
signal. 
NETWORK WINS – The Network signal always takes precedence over the Bypass button.
Energy
Management
DLC Stpt Bump
For load shedding applications, define the temporary setpoint shift to be added to the setpoint when the 
controller receives a Load Shedding command. By raising the setpoint during cooling operation, or reducing the 
setpoint during heating operation, the controller reduces the amount of heat or cool energy dissipated as a 
contribution to load shed algorithms. The parameter can be set in the range 0 to 10DDC (0 to 18DDF).
Cool Rec Ramp, Heat Rec Ramp
Define the rate at which the setpoint is reset during changes between occupancy modes to provide a form of 
optimum start algorithm.

PID
Cooling/Heating
Proportional band
This value is the temperature deviation between setpoint and space temperature, which causes the control 
output to modulate from 0 to 100% of full range. The variable can be set in the range 2 to 100 DDC (3.6 DDF to 
180 DDF), respectively; 1.3 to 100 DDC (2.3 DDF to 180 DDF) for P Control only.
Reset Time
This value is the integral reset time in the range 0 to 3200 sec. Setting the Integral constant to zero disables 
integral operation.
Derivative Time
This value is the derivative constant in the range 0 to 3200 sec. Setting the derivative constant to zero disables 
derivative operation.
