Some control functions are only accessible by the installer, service technician or the manufacturer.
Access is permitted by means of a password. The installer can ask the service technician for the password to be used to set the
functions he is allowed to access.
3.1.1 MAIN PAGE (g. 25)
The main page (g. 25) contains the following information:
A System date and time
B Current mode (Standby, cooling, heating, DHW only)
C Current functions (Climate curve, DHW Turbo, DHW OFF, anti-legionella, Night, ECO
D Alarms/overrides in progress (ashing)
E Values of the water temperature, system times on, Holiday, Rating
F Values of the water temperature, domestic hot water timers on, Holiday
G Mode, Tset, Tshow, Timers, Menu activation modes
3.1.2 OPERATING MODES (g. 26)
Touching the Mode icon on the main page calls up the set up page for the operating mode.
The selection icons for all the operating modes available appear on this page.
One or more operating modes are activated by touching the corresponding icons followed by the Conrm icon.
Touching the return icon returns you to the previous page (main or synoptic page).
Operating modes:
• Standby , the system is inactive
• Cooling , the system produces cold water until the set-point is reached (programmed or dynamic set point dened by
the climate curve)
• Heating the system produces hot water until the set-point is reached (programmed or dynamic set point dened by the
climate curve)
• ECO , the system produces water until the ECO energy saving set-point is reached (if the climate curve is activated,
the set point ECO is ignored)
• Night , the system limits the yield and noise level of the external unit
• DHW Turbo, the system produces domestic hot water regardless of the outside temperature using all the power of the
external unit up to the limit set (DHW temperature for DHW_A max 55°C)
• DHW off, the system does not produce domestic hot water but can perform other functions.
3.1.3 SET POINT (g. 27)
Touching the Tset , icon on the main page calls up the set up page for the set points.

The following information is shown:
• Incoming water temperature (domestic hot water air conditioning system in DHW_A mode)
• Outgoing water temperature (air conditioning system)
• Domestic hot water storage tank temperature
• Outside air temperature
• DHW outlet water temperature (high temperature DHW production circuit).
