5.5.3 Maximum Load Adjustment
Check the temperature control at maximum load as follows:
1. Go to:
Advanced Setup
→
Performance
→
Temperature Control
→
FFWD Settings
.
2. Ensure the
Outlet Feedback
parameter is set to
No
.
3. While monitoring the Valve Position bar-graph, create a maximum load on the system that
will yield a steady valve position between 80% and 90%.
4. Wait 2-3 minutes to allow the outlet water temperature to stabilize under load conditions.
5. Once stabilized, the outlet temperature should be within 3°F
of the unit’s setpoint.
6. If the outlet temperature is stabilized, no adjustment is necessary. If the temperature is not
stabilized, proceed to step 7.
7. Raise or lower
Max Load Adj
(
increasing
it will
increase
outlet water temperature), then
allow 2-3 minutes for the system to stabilize.
8. Repeat step 7 as needed until the temperature is stabilized within 2-3 °F (1.1 to 1.65 °C) of
the unit’s setpoint.
9. Set the
Outlet Feedback
parameter back to
Yes
.
10. If the outlet temperature does not maintain setpoint after a reasonable amount of time and
adjustment, contact your local PVI representative.
5.6 MODES OF OPERATION
Centurion Water Heaters operate in either
Constant Setpoint
or
Remote Setpoint
mode of
operation. The unit is factory preset with settings that work well, however, the setpoint
temperature is adjustable from 60°F to 170°F (15.6°C to 76.7°C).
As a prerequisite to both modes, you must ensure that the unit is
not
a WHM Client or Manager.
1. Go to:
Advanced Setup
→
WHM Cascade
→
Cascade Configuration
.
2. Verify that WHM Unit Mode = OFF.

5.6.1 Constant Setpoint Mode
Constant Setpoint mode is used to change the factory preset temperature to suit the demands
of the site. No external sensors are required. To set the unit to
Constant Setpoint
mode:
