COMMISSIONING
First boiler ignition
• Make sure there is no drawing of hot water and room thermostat requests.
• Turn on the gas and check that the gas supply pressure ahead of the unit complies with the technical data table or in any case the tolerance provided for by the
regulations.
• Electrically power the boiler; the display will show the software version number and then Fh and FH air venting cycle (see “9.2 Connection to the power supply,
switching on and off” on page 65).
• At the end of the FH cycle, the winter mode screen (fig. 158) will appear on the display; make the temperature adjustments: heating delivery and DHW outlet (fig.
162 and fig. 163).
• Check if the flue parameter value (““Sc” - Combustion Control Parameters Menu” on page 72) is suitable for the length of flue installed.
• In case of gas change (G20 - G30 - G31), check if the relevant parameter is suitable for the type of gas present in the supply system (““Sc” - Combustion Control
Parameters Menu” on page 72 and see “11.1 Heat pump alarms” on page 74).
• Set the boiler to DHW or heating mode (see “9.2 Connection to the power supply, switching on and off” on page 65).
• In Heating mode, carry out a demand: the display shows the radiator symbol and the actual heating system temperature; when the flashing flame symbol appears,
the burner is lit and the system is performing the calibration. Wait for the end of calibration, indicated by the steady flame symbol.
• DHW mode with hot water drawing: the display shows the faucet symbol and the actual DHW temperature; when the flashing flame symbol appears, the burner
is lit and the system is performing the calibration; wait for the end of the calibration, indicated by the steady flame symbol.
• Carry out the fuel check as described in par. “Checking the combustion values” on page 68.
12.3 Final check before turning on the unit
When the installation is complete and all the necessary settings have been made, reassemble and close all the panels of the unit.
12.4 Turn on the unit
When power is supplied to the unit, the remote controller display shows “1% ~ 99%” (initialization phase). During this process (which lasts a few seconds) the user
interface cannot be used.
To activate the system, refer to the section “REMOTE CONTROLLER - USER MENU” on page 32.
12.5 System water flow set point setting in heating mode
The heating set point can be modified by the user within some limits defined by the T1S RANGE settings in the HOT MODE SETTING menu of the remote controller
(see “fig. 171 - Heating with heat pump” on page 85)
T1S RANGE set to LOW (factory setting) 25
~
55°C
T1S RANGE set to HIGH 35
~
60°C
☞
NOTE:
To optimize the energy efficiency of the boiler it is suggested to set the boiler heating setpoint to the same value as the heat pump setpoint.
12.6 Setting of system water delivery set point in cooling mode
The cooling set point can be modified by the user within some limits defined by the T1S RANGE settings in the COOL MODE SETTING menu of the remote controller
(see “fig. 173 - Heating with heat pump and boiler” on page 85)
T1S RANGE set to LOW (factory settin) 5
~
25°C
T1S RANGE set to HIGH 18
~
25°C
12.7 Domestic hot water production temperature setting
To set the domestic hot water temperature (default 55 ° C) act on the boiler controller (see “DHW temperature adjustment” on page 66).
