Water Heater Management (WHM) Menu – (Software Version 3.08.xx Only)
Password Level 1 Options:
WHM Mode
This option is used to enable/disable the WHM Mode and set the
unit to function as a WHM Slave, or WHM Master. (Default = Off)
WHM Setpoint
This is the temperature (°F) that each unit in the WHM system is
trying to control to. (Default = 130°F)
Next On VP
This is the Next On A/F Valve position (%) for the system. When all
enabled water heaters have a fire rate greater than this value, it is
time to enable another water heater, if one is available. This value
should always be greater than the Next Off A/F Valve, and there
should be a reasonable spread between the 2 values.
(Default = 65%)
Next Off VP
This is the Next Off A/F Valve position (%) for the system. When all
enabled water heaters have a A/F Valve position greater than this
value, it is time to enable another water heater, if one is available.
This value should always be greater than the Next Off A/F Valve
position, and there should be a reasonable spread between the 2
values. (Default = 35%)
Lead/Lag Hours
This feature is basically designed spread the total number of run
hours accumulated on all units in the system so that each of the
units have approximately the same number of run hours. The
default value for this option is 72 hours,
WHM Upload Timer
Communication data logging period in seconds between 0 to 9999.
A value between 60 and 120 seconds is recommended.
Note: If OnAER is enabled for WHM the Min Upload Timer in the
Setup Men should be set between 300-600 seconds.
