4-24 High Limit Configuration Parameters

Table 4.11 displays Outlet High Limit configuration parameters.
Refer to 5-6 HIGH LIMIT RELATED CONFIGURATION for High Limit parameter programming.
Parameter
DHW high limit
DHW high limit response
DHW high limit setpoint
Auto or On CH pump operation
The CH pump can be turned on manually, or it can be set
to operate automatically. If it is turned on, it remains on
until changed back to Auto.
In Auto mode it operates according to the demand
sources listed for CH Pump Output and the overrun time.
0-600 seconds (0 = Not configured)
This time indicates how long the CH pump should
continue to run after CH pump demand or LL slave
demand ends.
Auto or On DHW pump operation
The DHW pump can be turned on manually, or it can be
set to operate automatically. If it is turned on, it remains
on until changed back to Auto.
0-600 seconds (0 = Not configured)
This time indicates how long the DHW pump should
remain on after DHW demand ends.
Auto or On System pump operation
The System pump can be turned on manually, or it can
be set to operate automatically. If it is turned on, it
remains on until changed back to Auto.
In Auto mode it operates according to the LL master and
slave demand and overrun time.
0-600 seconds (0 = Not configured)
This time indicates how long the System pump should
remain on after the LL master or slave pump demand with
overrun ends.
Days
If set to zero, the exercise function is disabled. Otherwise
this parameter provides the interval
time between exercising the pumps.
It is common to all three pump outputs.
0-600 seconds (0 = Not configured)
If the time is zero then the exercise function is disabled.
Otherwise this parameter provides
the time that a pump should be on when it is exercised.
It is common to all three pump outputs.

Disabled or enable DHW high limit
This parameter enables or disables the DHW high limit
function. It must be disabled when the
DHW input is used as a switch to indicate DHW demand.
Recycle & hold or Lockout
If lockout is selected then the burner control locks out. If
Recycle & Hold is selected then the burner control
recycles and holds until the DHW
temperature falls below the DHW high limit temperature
minus 5°F.
32 °F to 240 °F (0 °C to 115 °C)
If DHW high limit enable is enabled and the DHW
temperature reaches the value given by this parameter,
