6.1 - Before starting
WARNING !!! After complete the installation, fill
the system and purge the air with automatic air vent (“7”
Figure 3-1) before proceeding with start-up.
Before starting, a series of checks must be carried out to
ensure that the appliance can work in the best possible way:
1.- Make sure the fans rotate free;
2.- Verify that a metal mesh filter is installed on the return
(detail “2” of Figures from 4-2 to 4-6);
3.- Check that the power supply voltage is within the allowed
parameters with appliance “OFF” and at full output;
4.- Make sure the appliance’s grounding is valid;
5.- Check the presence of switches and electrical safety
devices;
6.- Check that all electrical connections are tight;
7.- Check that there are no leaks and ventilation is guaranteed
(as per Figure 5-5);
8.- Check that the condensation, produced by the appliance,
drains correctly;
9.- Check that the machine is installed more than 50 cm from
the ground or from the typical snow level;
WARNING !!! If all the controls are positive, you
can proceed with the first start-up, otherwise proceed
with the elimination of the anomaly.
10.- Check that the heating and cooling demand inputs (Figure
5-10) are closed. If these inputs are open it is possible to
force ignition by setting Parameter “08” (section 7.5) to
1,2,3 or 4, depending on the desired mode. Then, using
the “M” button, select the mode to be started, as described
in section 7.2.3;
WARNING !!! In this mode the appliance works
continuously at the temperature set as per section 7.2.4.
11.- If the appliance must also work in DHW, it is necessary
to check that the direction of the diverter valve (detail “8” of
Figures 4-5 and 4-6) is consistent with the heating and DHW
function. Otherwise it is necessary to operate on Parameter
“A9” (section 7.5), inverting the switching direction. Set
Parameter “A8” (section 7.5) to a value equal to or slightly
higher than the switching time of the diverter valve (detail
“8” in Figures 4-5 and 4-6).
6 - START-UP
6.2 - Start-up
1.- Start the unit by pressing the button on the display;
2.- After the appliance has worked properly for 10 minutes
without problems, the start-up is completed. In case of
errors or problems refer to section 8.
WARNING !!! Do not work the appliance in heating
or DHW mode if the outdoor temperature is higher than
43 ° C, in this case the unit goes into self-protection and
stops.
