Standby - Indicates that the Prestige is ready to respond when a
demand is received.
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 simultaneously. Both calls are being satised
simultaneously because domestic hot water priority has been dis-
abled.
DHW Priority - Central heating and domestic hot water calls are
being received simultaneously. Domestic hot water call is being sat-
ised rst because it has priority over central heating calls.
Priority Timeout - Central heating and domestic hot water calls are be-
ing received simultaneously. The domestic hot water priority time limit
has been exceeded. Priority will now switch back and forth between
central heating and domestic hot water calls until one call is satised.
External Demand - An external modulation call has been received.
Slave Operation - The Prestige is a slave in a cascade system.
Manual Operation - The burner or circulators have manually been
enabled in the Installer Menu.
CH Burner Delay - The burner will not re until the call blocking
time has elapsed.
DHW Burner Delay - The burner will not re until the call blocking
time has elapsed.
CH Setpoint Reached - The burner is not red because the sup-
ply/system water temperature exceeds the setpoint. The central
heating circulator(s) continue(s) to operate and the burner will re
again once the supply/system water temperature drops below the
setpoint.
DHW Setpoint Reached - The burner is not red because the sup-

Boiler Protection - The burner ring rate is being reduced because
of an excessive dierence between the boiler supply and return
temperatures. The ring rate will begin increasing once the tem-
perature dierence is less than 45°F [25°C].
Low Water Pressure - The system pressure has dropped to 10.1 psi.
The Prestige will still respond to calls until the pressure drops below
7.2 psi. Increase system pressure to 14.5 psi to clear Low Water Pres-
