CH Demand A central heating call has been received.
DHW Demand A domestic hot water call has been received.
CH / DHW Demand
Central heating and domestic hot water calls are being received simultane-
ously. Both calls are being satisfied simultaneously because domestic hot
water priority has been disabled.
DHW Priority
Central heating and domestic hot water calls are being received simultane-
ously. Domestic hot water call is being satisfied first because it has priority
over central heating calls.
Priority Timeout
Central heating and domestic hot water calls are being received simultane-
ously. The domestic hot water priority time limit has been exceeded.
Priority will now switch back and forth between central heating and domes-
tic hot water calls until one call is satisfied.
External Demand An external modulation call has been received.
Slave Operation
The Prestige is responding to a call from the master Prestige boiler in a cas-
cade system.
Manual Operation The burner or circulators have manually been enabled in the Installer Menu.
CH Burner Delay The burner will not fire until the call blocking time has elapsed.
DHW Burner Delay The burner will not fire until the call blocking time has elapsed.
CH Setpoint Reached
The burner is not fired because the supply/system water temperature
exceeds the setpoint. The central heating circulator continues to operate
and the burner will fire again once the supply/system water temperature
drops below the setpoint.
DHW Setpoint Reached
The burner is not fired because the supply/system water temperature
exceeds the setpoint. The domestic circulator continues to operate and the
burner will fire again once the supply/system water temperature drops
below the setpoint.
CH Post Pump
The central heating circulator is running to remove heat from the Prestige at
the completion of a call.
DHW Post Pump
The domestic hot water circulator is running to remove heat from the
Prestige at the completion of a call.
Freeze Protection
The burner is fired because the freeze protection feature has been activated.
Freeze protection will end once the supply/system water temperature is
raised to 60ºF [16ºC].
Boiler Protection
The burner firing rate is being reduced because of an excessive difference
between the boiler supply and return temperatures. The firing rate will
begin increasing once the temperature difference is less than 45ºF [25ºC].
Lockout Description The lockout which currently has the Prestige shut down is displayed.
