2.13 Circulation Pump Permanent Default: Disabled
Circulation Pump Permanent allows the circulators configured for central
heating calls in Pump Settings to be constantly enabled even without a
central heating call. The Warm Weather Shutdown function will disable
circulators enabled via this function. A domestic hot water call will cause
the circulators to be disabled during the domestic call as long as DHW
Priority is enabled. Press the UP or DOWN buttons to select Enabled or
Disabled then press the OK button to store the setting.
• Enabled – The central heating circulators will be enabled for con-
stant circulation without a central heating call.

ing a central heating call.
2.14 CH Post Pump Time Default: 5 Minute
CH Post Pump Time sets how long the circulators configured for central
heating calls in Pump Settings will continue to operate at the completion
of a heating call. The CH Post Pump feature allows the heat remaining
in the boiler at the completion of a call to be sent to the heating system,
which will improve the overall efficiency of the system. Press the LEFT
or RIGHT buttons to adjust the CH Post Pump Time then press the OK
button to store the setting.

disabled. Press the UP or DOWN buttons to select Enabled or Disabled

perature and responds as follows when no call is present:

to respond to a CH1 or CH2 Call are enabled.
- 60°F [15°C] – Freeze protection ends. Burner & all pumps turn
OFF after completing CH Post Pump Time.
