energized without the boiler stopping. Once the
DHW cycle has completed, the boiler will stop
and wait to be called again for either space
heating or DHW heating. A shutdown always

10. Set the LOCAL PUMP OFF value to NO.
This will leave the local pump on during a
DHW heating cycle (backwards compatibility).
Setting this value to YES will turn off or keep
the local pump off.
Setting this value to YES, will shut the local
pump off during a DHW heating cycle, but will
keep the local pump on for the LOCAL
DELAY: 10s time before shutting off. This
LOCAL DELAY: time can be adjusted in the
next menu item by pressing the down arrow
again.
11. Set the PURGE TO value to TANK. This will
purge the heat from the boiler into the tank or
system loop. This will be done using the DHW
pump after the DHW heating cycle is complete.
If the PURGE TO: is set to SPACE, once the
DHW cycle has completed, the boiler will shut the
DHW pump off within a few seconds. The SPACE
setting is to be used only for mixed space and DHW
heating.
