If SHARING is set to NO CYCLE, a hot swap
will occur. A hot swap is when the boiler is
running in space heating mode and does not need
to be shut down. The DHW pump/valve will be
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
occurs after a DHW cycle completes.
10. Set the LOCAL PUMP/VALVE OFF to NO.
This will leave the local pump on during a DHW
heating cycle (backwards compatibility).
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 (Programmable) time before
shutting off.
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.
