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.
Mask Gfc23: enabling external reports
•
It enable warning reports on output NO7: it
allows to enable the digital output NO7, to
whom it could be connected for example a
notification led, when the machine is in alarm
for minor causes.
Mask Gfc25: defrosting setting.
•
Fan consumption: fan consumption in Watt
calculated by the electronic and used to start
the defrosting procedure.
•
Start up delay: start up delay of the compressor
after that it is allowed the defrosting start up.
To avoid that the defrost starts just after the
ignition of the compressor, situation where
you can have the conditions of the defrost
start up, due to the start up dynamics.
•
Fan delay: waiting time before of starting the
defrost
•
Defrost delay with temperature differencies:
Waiting time for the activation of the defrost
for delta T.
Mask Gfc27: parameters defrost.
•
En oil defrost: element that allows to enable
the returno of the oil through defrost cycle. If
enabled and if the unit required the return of
the oil normal defrost procedure is activated
with maximum settable speed with the
following parameter “Defrost Speed”.
•
Low speed defrost: if ate the moment of
defrost start up the compressr had a lower
speed than the Thershold the compressor
speed during the defrost will be defrost speed.
Mask Gfc34: drip parameters.
•
Drip manag.: it enables the operation of
the fan before the inversion of the 4-way in
output from the defrost cycle, that rotating at
a high rpm promotes the disposal of the water
drops still in the battery.
•
Fan Dripping Speed: it is the speed where the
fan is forced il ventilatore in this specific phase
of the defrost process.
•
Fan reverse Dir: it allows to enable or not the
reversing of the rotation direction of the fan.
If enabled, the dripping is made with a fan
that turns in the opposite.
Mask Gfc37: defrost parameters.
•
Integration of the system during the
defrosting.: It enables the integration
generator to the system (boiler or electric
resistance).
•
Def. end max time exceeded: it allows
to choose between HISTORY and
ALARM, that is to choose the
registration/reporting mode of the event “the
defrosting is finished because the maximum
time is exceeded”.
Mask Gfc50: It allows to enable the condensate drain
in fix or intermittent mode in base on the external
temperature.
•
Res.drain cond.: it enables the activation of
the resistance for the condensate drain.
•
ALWAYS ON (Set1): in this condition,
the resistance is always active under this
parameter
•
Set: value of temperature reached that the
resistance condensate drain is always active.
•
Diff: differential of temperature. When the
xternal temperature is equal to Text= Set+Diff
you go out form this function
•
MODE ON-OFF (Set2): in this condition
the resistance is activated under the set, at
time intervals as defined from the following
parameters.
•
Set: value of temperature reached that the
function is activated.
•
Diff: differential of temperature. When
the external temperature is equal to Text=
Set+Diff you go out from this function
•
T.On: time of on of the resistance in minutes.
•
T.Off: time of off of the rsistance in minutes.
Mask Gfc51: limitation in power consumption.
•
En.Watt limit rps: Enabling of maximum
allowed speed limitation to compressor for
work of the effective consumption in watt.
•
Thr.: maximum threshold reachable by the
total consumption (compressor, fan, auxiliary,
circulator, auxiliary…)
•
Band: Band in which the value of instant
consumption can swing, but always staying
under the threshold set
•
Fan: Consumtion value read by the fan. The
reading is possible only thanks to the protocol
od communication modbus (protocol to
communicate) RS 485 (physic network
constitued by a certain number of wires), it is
set in one to read the effective consumption
value
•
Aux: Consumption values of the auxiliaries.
Set equal to 20 W costant.
•
Update time: interval of time passed that
you have the update, up or down, if all
the conditions aloow it, the variable that
contains the maximum speed allowed by the
comporessor.
•
Update rps: positive or negative increasing
of the variable that contains the maximum
speed available by the compressor.
Operation:
•
if Thr is< the current consumption of the unit
the limitation of the maximum rpm of the
compressor starts decreasing of “Update rps”
every “Update time”
•
if the current consumtion is included between
(Thr-Band) and Thr correction actions aren’t
made
•
if the current consumption is < than (Thr-
Band) the compressor is free from binds (the
maximum speed allowed can increase)
Mask Gfc56: it aloows to change the intervention
threshold of defrosting.
•
Model: fan model present in the heat pump.
•
Amp: parameterization defrost.
