MENU LEVEL & OPTION
DESCRIPTION
WHM MENU
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)
WHM Nxt On VP
(See NOTE at end of page)
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%)
WHM Nxt Off VP
(See NOTE at end of page)
This is the Next Off A/F Valve position (%) for the system.
When all enabled water heaters have a A/F Valve position less
than this value, it is time to shut down another water heater, if
one is available. This value should always be less than the
Next On A/F Valve position, and there should be a reasonable
spread between the 2 values. (Default = + 35%)
Lead/Lag Hours
The Lead/Lag Hours menu option is basically designed to
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.
Setback Setpoint
This is the setpoint temperature (°F) that each unit in the WHM
system is trying to control to during periods of low (or no) DHW
demand. The setback setpoint temperature can be set from
40°F to 220°F. (Default = 130°F)
Setback Start:
Setback End:
Specifies the start and end times that the Setback Setpoint will
be in effect. (12:00am – 11:59pm)
WHM Auto Mstr
Enables (Yes) or disables (No) an Automatic WHM Master
Switch-Over function. When enabled (Yes) the WHM will
automatically select a new Master if the current Mater fails or
loses power. (Default = No (Disabled))
WHM Auto Timer
When the WHM Auto Mstr option is set to Yes (Enabled), the
WHM Auto Timer option allows the user to select the elapsed
time interval between failure of the WHM Master and switch-
over to a new WHM Master. The default for this option is 30
seconds. The allowable entry range is 10 seconds to 120
seconds.
NOTE
The WHM Nxt On VP and WHM Nxt Off VP will determine how tight a range the
temperature is controlled over and how quickly the system responds to a change in load.
A narrow difference between Nxt On VP and WHM Nxt Off VP will make the system more
responsive to load changes.
