•
Diff.off HWD: temperature threshold under
that integration system for HWD turns off.
•
Delay ON: activation delay of the integration
once respected the conditions above.
Mask Gfc06:
setting of the temperature curve.
•
Regulation of temp. primary system: the
choice is between the wording “FIX POINT”
and 3-POINTS CURVE:
FIX POINT: the machine adjusts according to the
setpoint set, every temperature of the external air
3-POINTS CURVE: it is the setting suggested by us. It’s
impossible directly set the three temperature points
external/set point temperature, the logic builds a

Heating curve setting
It is also displayed the nominal active Set.
Changing the nominal Set from the menu SETPOINT
(B01) the entire climate curve will have a translation
positive or negative according to the Set. (for example,
changing the nominal set from 35°C to 33°C the whole
curve will lower 2°C in every working condition).
Mask Gfc07: riserved
Mask Gfc08: circulator management disabled puffer.
•
Delay OFF: when the compressor stops, the
circulator works for the number of seconds
set
•
start delay: time in minutes from the turning
off of the compressor to the start up of the
function;
•
Pump ON time: circulator operation time;
•
Pump OFF time: circulator stop time
Maschera Gfc15: reset antifreeze alarm.
•
Reset antifreeze alarm primary circuit: it
allows to establish if the rearming is manual
or automatic.
•
Manual: (default) the machine restarts only if
the user resets resetta manually the alarm.
•
Auto: the machine restarts automatically
when the flow temperature is increased to
the value Set_alarm_anti Diff._Activat
Mask Gfc16: circulator operation mode.
•
It actives pump primary circuit: it is possible
to choose “ON DEMAND” e “ON UNIT’”.
•
On demand: the circulator just starts if
required by the heat pump (that is when there
is a request for the ignition of the compressor
or to manage possible antifreeze alarm).
•
On unit: the circulator starts when the unit
is ON.
•
Pump for antifreeze: it enables the activation
of the pump (circulator) for the function
antifreeze winter.
Mask Gfc17: Setpoint on the system temperature
for the activation of the antifreeze that activates the
circulator.
Set antifreeze pump primary circuit: temperature set
that activates the winter antifreeze protection. When
the flow temperature (sensor B7) is lower than the
value set hear, the circulation pump is activated to
keep a continuous flow in the hydraulic lines.
•
Diff. Activat. antifreeze pump: the pump,
activated by the antifreeze protection,
continues working until the flow temperature
is equal to Set+Diff.
Mask Gfc18: Setpoint on the external temperature for
antifreeze activation that activates the circulator.
•
Setpoint: value of external temperature
under that winter antifreeze function is
activated. That is it starts the circulator for the
recirculation of the water in the pipelines.
•
Diff.: differential of temperature that, added
to the setpoint, determine the temperature
of the external air that blocks the winter
antifreeze function when it is active.
•
Time ON and Time OFF represent the cycle of
activation and shut down of the heat pump
during the function of winter antifreeze
protection. Time ON and OFF are expressed in
minutes
NB: the setpoint of these screens (17 and 18) depends
on the type of installation. For example with air sensor
B8 exposed to the sun an incorrect value coud be read
and nullify the function. If the sensor is exposed to the
sun we suggest to install a remote sensor and install it
in a shady place.
Mask Gfc20: resetting set overheating reset .
•
Reset overheat. alarm primary circuit: it
permits to establish if the restting is manual
or automatic.
•
Manual: (default) the machine restarts only
if the user resets the alarm manually.
•
Auto: the machine restart automatically
when the flow temperature is decreased to
the value Set_alarm_overheat-Diff._Activat.
Mask Gfc21: selection for the setting of the mode
(winter or summer) through user panel or remore
external switch (digital).
•
Summer/Winter selec. Season from: it is
possible to choose between “KEYBOARD”
(operator panel) or “IN. DIG. 1” . In this case
you have to consider it isn’t enough to manage
the commutation summer/winter but also the
production of the domestic hot water if the
unit has also to produce DHW. About this see
documents relevant to the function no puffer
in the end of the manual.
Mask Gfc22:
•
Enable protection: it allow to enable or not
the function winter antifreeze protection that
activates the compressors when the plate heat
exchanger reaches a temperature too low.
