CH2 Minimum Setpoint is the minimum setpoint for a
CH2 heating call when an Outdoor Curve option is chosen
in Demand Type. This setting is not applicable when a Set-
point option is chosen in Demand Type.
Adjust the CH2 Minimum Setpoint value using the LEFT or
RIGHT keys, then store the setting with the OK key.
Default: 80°F
CH Post Pump Time sets how long the central heating
circulators will continue to operate at the completion of a
heating call. Any call during the CH Post Pump Time will be
ignored until the post pump has completed. The CH Post
Pump Time feature allows the heat remaining in the appli-
ance at the completion of a call to be sent to the heating
system, which will improve the overall eciency of the sys-
tem.
Adjust the CH Post Pump Time value using the LEFT or
RIGHT keys, then store the setting with the OK key.
Default: 5 min
Warm Weather Shutdown allows to enter an optional outdoor
temperature at which to disable the central heating function. The
Appliance will continue to respond to a domestic hot water call
or a 0- 10V Modulation Signal when the outdoor temperature ex-
ceeds the Warm Weather Shutdown Temperature setting.
Adjust the Warm Weather Shutdown Temperature value us-
ing the LEFT or RIGHT keys, then store the setting with the
OK key.
The Warm Weather Shutdown icon ( ) is displayed on the
home screen when the outdoor temperature reaches the
Warm Weather Shutdown Temperature.
Default: OFF.
Circulation Pump Permanent allows the central heating
circulators to be constantly enabled even without a central
heating call. A domestic hot water call will cause the circula-
tors to be disabled during the domestic call as long as DHW
Priority is enabled.
Select Enabled or Disabled using the UP or DOWN keys,
then store the setting with the OK key.
• Enabled – The central heating circulators will be enabled
for constant circulation without a central heating call.
• Disabled – The central heating circulators will only be
enabled during a central heating call.
Default: Disabled
