15 - USE
15.1 - Check water
pressure
If the pressure inside the water circuit
falls below the minimum pressure for
the system, the appliance switches
off and the display "N" as per Figure
15-1, shows Err 59 to indicate that
it is necessary to restore the correct
pressure. Because appliance is installed
in an open loop system, you have to
check for the net water pressure or for
any pressure reducer upstream of the
water supply circuit. When the pressure
is restored the Err 59 will disappear.

15.2 - Overview

The appliance is pre-set with standard
parameters. However, it is possible to
make a number of changes or consult
the parameters by means of using the
"Users' Menu" (see Section 15.10)
and the "Installers' Menu" (see Section
15.11). During functioning display "N"
of Figure 15-1, displays the supply
temperature, and display "M" (see
Figure 15-1) shows the pressure of the
water. The various operating statuses
are shown with other icons as per
Figure 15-1.

15.6 - Delays, alarms
and protective actions
To protect the life of the appliance,
improve comfort, and maximize energy
savings, the following timings have been
incorporated into the control logic:
a - Pump delay: each time the room
thermostat is satisfied, the circulator
pump continues to run for 4 minutes;
b - DHW delay: each time the domestic
hot water demand is satisfied, a 4
minute delay pass before the end
of the service (if a need for heating
is present the 4 minute delay is by-
passed);
c - Time delay in restarting the burner:
in its normal functioning state, every
time the burner stops, there is a delay
time of 3 minutes before the burner
starts again.
15.7 - Circulator
pump protection
During stand by state, circulator pumps
run once a day for around 15 seconds
to prevent them from seizing.
15.8 - Appliance's
Freeze protection
CAUTION!!!
F o r t h e f r e e z e
protection function to work, the
appliance must remain connected to
the electrical and gas supplies with
heating service switched to OFF
CAUTION!!!
T h i s
protection function is conceived to
protect the appliance only, not the
system.
Once the appliance has reached a
temperature of 50 °F (10 °C), the local
pump will automatically comes on. If the
temperature falls below 41 °F (5 °C), the
burner will light to prevent the appliance
from freezing. If the appliance will not be
used for long time it should be drained
per Section 16.9.
15.9 - Display in
energy saver mode
The display, in Figure 15-1, is switched
off each time no key is touched for at
least 5 minutes, with the exception of
when it displays errors or settings. If you
want to leave the display continuously
ON, set parameter 2100 to 0 (zero) (see
Section 15.11.
