Parameter 13
ANTILEGIONELLOSIS
The d.h.w. calorifier is overheated at 70°C / 158°F
every Saturday from 4h to 5h. The "antilegionellosis"
function acts to prevent the development of legionella
in the calorifier, these bacteria are responsible for
legionellosis.
Note
When you want to activate the antilegionellosis function,
you should:
- increase the boiler thermostat setting to 80°C / 176°F.
- provide a mixing device preventing water from being
distributed at a temperature greater than 60°C / 140°F
in the domestic hot water distribution network.
Parameter 14
HEATING PUMP AND DHW PUMP TIMEOUT
- a timeout to switch off the heating pump prevents
overheating of the boiler when changing from winter
conditions to summer conditions, since this could acci-
dentally trip the safety thermostat.
- the timeout when switching the d.h.w. heating pump
off prevents excessively hot water from entering the
heating circuit after the calorifier heating has been
stopped. It also prevents overheating in the boiler,
which could accidentally trip the safety thermostat.
Parameter 15
CDC MEMORY CHECK
To display the memory number used on a communica-
ting remote control.
Parameter 16
CPU MEMORY CHECK
To display the number of the memory used on the E
control panel regulation card.
Parameter 11
EXTERNAL FROST FREE
Below this temperature, the pumps run continuously
and the minimum circuit temperature is respected. For
Night Off operation (setting 0), Night Off mode (setting
1) becomes active.
Parameter 12
DOMESTIC HOT WATER PRIORITY
To make the following selections when a calorifier is
connected:
- DHW PRIORITY (setting 1): absolute priority to
heating of domestic hot water: the heating pump is
switched off,
- DHW NOT PRIORITY (setting 0): the heating is not
cut off when the calorifier is being heated
Important
The temperature in the radiators can reach the maxi-
mum programed value for the boiler while the d.h.w.
calorifier is being heated.
