Table 4.14 – Frost Protection Configuration Parameters
Disabled or enable DHW Storage.
If it is disabled then the other DHW storage parameters
are ignored.
This parameter provides the DHW storage time. When
enabled and normal DHW call for heat is satisfied the
DHW storage demand will persist for this time interval. If
normal demand returns the timer is reset.
This parameter provides the setpoint used during DHW
storage demand.
Differential above setpoint when boiler is turned on
2 °F to 30 °F (1 °C to 16 °C)
Differential above setpoint when boiler is turned off
2 °F to 30 °F (1 °C to 16 °C)
Table 4.15 – DHW Storage Configuration Parameters
Disabled or enable WWSD.
Disable: WWSD is not active.
Shutdown after demand ended: Any current CH
demand that is present prevents WWSD from becoming
true. WWSD becomes true when CH demand is
satisfied.
Shutdown immediately: When WWSD becomes true, it
immediately cause CH demand to end.
Setpoint temperature at which activates WWSD.
