display. If an external pressure gauge is present,
it is permissible to change the setting to "No."

in the OFF (default) position. Select the proper
curve from below. See section "12.5 Outdoor
Reset Control" for more information.

Fire in CH Mode
This parameter is available when DIP switch 1 is
in the OFF (default) position.

This sets the maximum outdoor temperature
the boiler will fire in CH mode. This can prevent
the boiler from firing in warm outdoor
temperatures.
Maximum DHW Set Point Temperature
This selects the maximum DHW set point
10
temperature. When 140°F, it is recommended
to have a mixing valve to prevent scalding.

This selects the length of time the 3 Way Valve
will stay in the DHW position after using DHW

even if a CH demand is present.
While the 3 Way Valve is in the DHW position,
this enables quicker delivery of hot water.
DHW Recirculation Piping Setup
This parameter is available when DIP switch 3 is
in the ON position. This sets the DHW
12
recirculation piping mode, which controls the
circulation logic. Ensure this corresponds to the
