frost Protection

With the addition of the IDWH sensor, the Prestige Control

module will now provide a Frost Protection feature to the

SMART tank. This feature becomes active when

Parameter 46 is set to 12 and cannot be overridden.

The Frost Protection feature is designed to protect the

SMART IDWH from a potential freeze up. The protec-

tion is activated once the IDWH sensor records a

domestic temperature of 37ºF. At that time the Prestige

boiler will begin the burner function at low input and the

DHW circulator will begin circulating. The burner will

continue operating at minimum input with the DHW cir-

culator energized until the sensor senses a domestic

water temperature of 50ºF. At that point the boiler will

shut down the burner function and the DHW circulator.

This feature is always active even if the DHW operation

is in the OFF mode.

Misc. functions

There are several other Parameter settings available for

DHW applications, i.e. post pump features, blocking time

for burner operation. These features are explained more

in detail in the Prestige Control Supplement.
