Additional DHW Feature

DHW Frost Protection

The Indirect Water Heater (IDWH) Sensor used in the Prestige Excellence provides

a Frost Protection feature to the water heater. The Frost Protection feature is

designed to protect the Excellence water heater from a potential freeze up. Frost

Protection will generate a DHW call once the IDWH temperature falls below 42º F

[6ºC]. Once Frost Protection is activated, the internal circulator and diverter valve

will direct water flow to the water heater and the burner will fire. Frost Protection

will end once the IDWH temperature is raised to 60ºF [16ºC]. This feature is always

active and cannot be disabled. Frost Protection is still active even if DHW opera-

tion has been disabled.
