8.1.3.9 Different operating mode start
conditions
Each operating mode must comply with precise
conditions in order to be enabled:
AUTOMATIC operating mode
The condition in order to enable the start of this
function is as follows: lower probe< SP2 – r0
(hysteresis);
ECO operating mode
The condition in order to enable the start of this
function is as follows: lower probe< SP1 – r0
(hysteresis);
OVERBOOST operating mode
The condition in order to enable the start of this
function is as follows: lower probe< SP3and upper
probe< SP3.Once a temperature exceeding SP3
has been detected, the Overboost operating mode
terminates and the previously set operative mode
is restored.
8.1.3.10 The display
If the equipment is in the "ON" status, during normal
operation, the display will show the established
temperature by means of parameter P5:
If P5 = 0, the display will show the temperature of
the upper part of the boiler;
If P5 = 1, the display will show the active working
set point;
If P5 = 2, the display will show the temperature of
the lower part of the boiler;
If P5 = 3, the display will show the temperature of
the evaporator;
If the equipment is in the "stand-by" status, the
display will be switched off.
8.1.3.11 Alarms
N
OTE
In case of "UtL" alarm (fault of the fan), in
addition to the display visualization, the
equipment emits an acoustic signal that can
be switched off pressing any key on the
controller. The alarm it is never canceled
unless the equipment is switched off or put in
stand-by.
The heat pump working mode is automatically
disabled and the one with electric resistance is
activated in order to ensure the continuity of
the warm water supply.
PLEASE NOTE!
In case of "UtL" alarm it is necessary to
contact the technical assistance.
