14.4 - Ignition and shutdown procedure
To switch on the appliance, proceed as follows:
1.- open the gas valve;
2.- power the appliance;
3.- If the display shows
Err
65
, it means that phase and
neutral polarity were not respected (call customer service
to solve the problem without attempting to fix it yourself).
4.- adjust the domestic hot water temperature as per section
14.5.
The command and control equipment will ignite the burner.
If ignition is unsuccessful within 3 minutes, the appliance
automatically attempts ignition five times, after which, if it
continues not to switch on, it locks up and the display will
show
Loc
1
along with the icon
and the corresponding
flashing burner icon. Press the RESET key to restore
normal operating conditions. The appliance will automatically
attempt another ignition.
WARNING!!! If the appliance frequently stops
because it locks up, contact a qualified technician to reset
normal operating conditions.
Once started properly, the appliance will continue to work for
the service requested.
To switch off the appliance, proceed as follows:
1.- Use switch “T” in figure 14-1 to cut power;
2.- close the gas valve;
14.5 - Temperature adjustment
To adjust the temperature, use the
or
keys (see
figure 14-1)
. When the keys are pressed, the display, part “N”
in figure 14-1, shows the requested temperature. The water
temperature adjustment range goes from 20°C to 80°C.
WARNING!!! Domestic water temperature over
51°C can cause scalding. Children, the disabled and
the elderly are at high risk for scalds. Check the water
temperature before getting into a bath or shower.
14.6 - Antifreeze protection
WARNING !!!
In order for the antifreeze protection to be effective,
the appliance must be left with the power and gas
supply on and the domestic water service in the
OFF
position.
WARNING !!!
The antifreeze protection provided by the appliance
cannot ensure antifreeze protection for the domestic
water system, nor for the building being served or parts
of it.
Once the temperature of 10°C is reached, the pump
automatically switches on. If the temperature drops further
below 5°C, the burner also switches on in order to protect
the appliance from the effects of frost.
If you do not use the appliance for a long period of time (over
a year), we recommend draining it, following the procedure
in section 15.10.
14.7 - Energy Saving
To reduce display energy consumption (Figure 14-1), it
switches off automatically 5 minutes after the last operation
done. You can disable this function or edit the time via
parameter
2100
in the “installer menu” (section 14.9). If you
set the parameter to
0
, the display will remain on constantly.
