Table 15. DHW Storage Demand Parameters.
Parameter
Comment
DHW storage enable
Enable, Disable
This parameter enables or disables the DHW storage feature. If it is disabled then the other
parameters below are ignored.
DHW storage time
mm:ss
The time DHW storage temperature is maintained.
DHW storage setpoint
degrees or None
The temperature setpoint that the boiler maintains during the DHW storage time.
DHW storage on hysteresis
degrees or None
This provides the on hysteresis as an offset that is applied to the DHW storage setpoint, used
during DHW storage demand.
DHW storage off hysteresis
degrees or None
This provides the off hysteresis as an offset that is applied to the DHW storage setpoint, used
during DHW storage demand.

DHW FORCE TAP PREHEAT
WHENEVER PREHEAT IS FALSE:
IF TAP IS TRUE, INHIBIT THIS PREHEAT BLOCK, RESET THE
ITEMS, AND RESET THE PREHEAT DELAY-AFTER-TAP TIMER.
IF PREHEAT IS FALSE, IT BECOMES TRUE WHEN:
WHEN THESE HAVE OCCURRED, THEN A 1 MINUTE TIMER STARTS.
WHEN THIS TIME ELAPSES, THEN PREHEAT ENDS. THE FORCE OUTPUT IS PULSE
TO FORCE TAP DETECTION TO START (AND PREHEAT IS INHIBITED). THIS ALSO
OCCURS IMMEDIATELY IF THE 1 MINUTE TIMEOUT IS PENDING BUT PREHEAT
ENDS DUE TO ABOVE.
WHEN PREHEAT TURNS ON, ITS MINIMUM ON TIME IS STARTED
IF PREHEAT IS TRUE, IT BECOMES FALSE WHEN:
IF TAP IS FALSE, ALLOW THE TIMER TO RUN.
•TIME IS EXPIRED, AND
•SET IS FALSE, AND
•CLR IS TRUE
•TAP DURING PREHEAT IS RECOGNIZED AS:
• TAP HAS BEEN TRUE WHILE PREHEAT WAS TRUE
• EITHER • INLET TEMPERATURE DECREASES BELOW THE LEVEL

• DHW >= INLET
•TAP DURING PREHEAT IS RECOGNIZED (SEE BELOW)
•BOTH: • DHW <= PREHEAT (SOFF HYSTERESIS)
• PREHEAT MINIMUM ON TIME HAS EXPIRED
•TAP IS FALSE
•THE PREHEAT DELAY-AFTER-TAP TIME HAS ELAPSED
