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 disabled.
DHW Priority - Central heating and domestic hot wa-
ter calls are being received simultaneously. Domestic
hot water call is being satised rst because it has prior-
ity over central heating calls.
Priority Timeout - Central heating and domestic hot wa-
ter calls are being 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.

been received.
Slave Operation - The EXALT is a slave in a cascade sys-
tem.

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 supply/system water temperature exceeds the set-
point. 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 be-
cause the supply/system water temperature exceeds the

perature is raised to 60°F [16°C].
Boiler Protection - The burner ring rate is being re-
duced because of an excessive dierence between the
boiler supply and return temperatures. The ring rate
will begin increasing once the temperature dierence
is less than 45°F [25°C].
Low Water Pressure - The system pressure has dropped
to 10.1 psi. The EXALT will still respond to calls until the
pressure drops below 7.2 psi. Increase system pressure
