CHAPTER 3 - DHW SETTINGS (PRESTIGE, HEATMASTER AND INSTINCT SOLO)
The Antilegionella Function ensures that an Indirect Water
Heater is heated at least once per week to prevent the growth of
Legionella bacteria.
Select Enabled or Disabled using the UP or DOWN keys, then
store the setting with the OK key.
• Enabled- When the Thermostat option is chosen in De-
mand Type, a domestic hot water call is generated for 15
minutes once per week to heat the Indirect Water Heater.
When the Sensor option is chosen in Demand Type, a domes-
tic hot water call is generated until the DHW storage tempera-
ture reaches 140°C once per week. When the Sensor option is
chosen in Demand Type, the weekly timer is reset whenever the
DHW storage temperature reaches 140°C to prevent unneces-
sary rings. This function will be active even if DHW Operation
has been set to Disabled.
• Disabled - The Appliance will only re in DHW mode when
a domestic hot water call is received.
Default: Disabled
The antilegionella function should only be enabled
when an Indirect Water Heater is installed. Enabling
the antilegionella function without an Indirect Wa-
ter Heater will result in the Appliance firing once per
week in DHW mode. This could cause a Manual Re-
set Hard Lockout of the appliance.
The antilegionella function is most effective when the
Sensor option is chosen in DHW demand. The use of an
Indirect Water Heater Sensor ensures that the domestic
hot water is heated to 140°F at least once a week.
