The temperature of the domestic hot water is adjusted by
operating on the
and
keys. On pressing one
of the two keys, the visual display “H” in figure 7.1 will start to
flash and show the temperature that is being set. The range
of adjustment for the temperature of the domestic hot water

7.6 - Pump control features
To safeguard the lifespan of the appliance, improve the comfort
generated and increase energy saving, timings have been
introduced during operation.
These timings are:
- Pump post-circulation: every time the domestic hot water
service ends, the pump continues to operate for 2 minutes;
- Pumps anti-block: every 24 hours the recirculation pump
and the storage tank loading additional pump (if present)
are forced;
- Anti-legionella; if the appliance is connected to a storage tank
for preparation of the D.H.W., every seven days the latter
is forced to a temperature of 60°C to disinfect against the
legionella bacteria. This function activates also two hours
after the appliance has been powered electrically.
7.7 - Pumps anti-block
The pump switches on once every 24 hours for 15 seconds
during the summer period in order to prevent any deposits
that may block it.
The storage tank loading pump (if present) is activated at
the same time for the same reason.
7.8 - Display Energy Saving mode
To reduce the consumption of display energy, it will switch
off automatically after 5 minutes from the last operation
performed. This function can be deactivated or the time
modified via parameter
2100
present in the “Installer menu”
(see chapter 7.10). If the parameter is set at
OFF
, the display
will remain on constantly.
