2.2.4 Operation in winter mode

the "System Manager Kit" enables both domestic hot
water production and room central heating (M01).
The display shows current day and time, any operating
faults, ambient temperature and humidity percentage
in the main area.
N.B.: press arrows
for any other stored areas.
The "System Manager Kit" allows automatic functioning
in central heating mode, in which a time program man-
ages the room temperature during the hours of the day.
The desired room temperature can be adjusted onto
two independent levels: comfort (
(
). The distribution of these levels throughout the
day or week is controlled by the hourly programming
(see Parag. 2.5).
The "System Manager Kit" is factory set as shown in
the table below. If this should not satisfy requirements,
it is possible to modify it as described in the following
chapters.

N.B.: the system is designed to function on comfort
and reduced temperature levels depending on the hour
program set. Therefore also during functioning in re-
duced temperature conditions, if the room temperature
measured is below that set, the system can switch-on.
2.2.5 Room antifreeze function
Note: this function is only active in the winter, stand-by
and summer mode.
The antifreeze function has maximum priority with
respect to other settings. When ambient temperature
drops below 5°C a central heating request at minimum
setting is made. This situation remains active until there
is a variation in room temperature of 1°C equal to 6°C
measured in the area where the temperature below 5
°C is detected.
