3.2.3 User
menu
The following functions modi able from the user menu can also be activated on the internal unit’s control panel:
• CLOCK
To set the clock, modify parameter hrS for the hours and parameter in for the minutes.
•
TIMER
With this function the system can be set to switch on and off once a day.
Parameter
ti
1 activates the function, parameter StA sets the start time and parameter Sto sets the system shutdown time.
•
NIGHT-TIME MODE
System yield and noise are limited in night-time mode.
The function is enabled with parameter ncL 1, the mode start time with parameter nSt and the end time with parameter nSP.
•
COOLING SET-POINT
The thermostat can be set for two different water cooling temperatures, using parameters CS1 and CS2.
Temperature CS2 is used by activating Eco mode in cooling.
• HEATING
SET-POINT
The thermostat can be set for two different water heating temperatures, using parameters HS1 and HS2.
Temperature HS2 is used by activating Eco mode in heating.
•
DOMESTIC WATER SET-POINT
The thermostat can be set for one water heating temperature, using parameter HS3.
• CLIMATE
CURVES
To optimise energy saving, two climate curves are available: one for heating and one for cooling. This function enables the
water temperature to be adjusted to the outside air temperature and therefore to the heating load, optimising system energy
saving.
The climate curves must be set on the system by authorised personnel, modifying certain parameters in the service menu.
The user can enable the curve in heating by setting parameter Hcc 1; with Hcc 0 the curve is disabled and the system runs
with set-points Hs1 and Hs2.
The user can enable the curve in cooling by setting parameter Ccc 1; with Ccc 0 the curve is disabled and the system runs
with set-points Cs1 and Cs2.
