temperature must be allowed to settle for several minutes prior to making any further
adjustments.
When calibrating temperature controls, observe the following:
• The unit must be in the Auto mode of operation.
• The Outlet Feedback option (in the Tuning Menu) is typically turned on in normal
operation, but it must be disabled while performing Min Load Adj (Section 4.6.2).
• Monitor the outlet temperature displayed on the Controller and Valve Position bar-graph to
set load conditions and observe the effect of adjustments.
• Calibration is performed the using the Edge Controller’s Tuning Menu.
• Make small adjustments and allow time between adjustments for the outlet water
temperature to stabilize.
• Maintain water flow as constant as possible during these adjustments.
• Ensure that recirculation loops are operational while the calibration is being performed.
• Upon completion of calibration, set the Outlet Feedback back to ENABLE.
Temperature control calibration is accomplished by first performing the procedure in Section
4.5.2: Minimum Load Adjustment. Once that is complete, you can then perform the procedure in
Section 4.5.3: Maximum Load Adjustment, below.
4.5.1 Setting the Outlet Water Temperature Setpoint
If the setpoint is already set to the correct values for the site, skip this step and proceed to
Section 4.5.2. However, if necessary, the current setpoint can be changed using the instructions
below.
1. On the WHM Manager unit, go to: Main Menu → Advanced Setup → WHM Cascade →
Application Configuration.
2. The Setpoint for the WHM Cascade can be a constant, or received from a remote source,
such as a BAS (building automation system).
• If Operating Mode = Constant Setpoint: Set WHM Setpoint to the desired setpoint.
• If Operating Mode = Remote Setpoint: Choose the source of the remote setpoint:
