Push and release the
SET
key, the leds of the circuits are off and the set value is displayed.
In stand-by the bottom display shows
SetC
(set chiller), by pushing SET again the next label is
SetH
(set
heat pump ).
If the unit is running the only set displayed is related to the running mode.
Modify the Set Point
1) Push
SET
key for at least
3
seconds: the leds of the circuits are off and the set value is blinking.
2) Use the
UP
or
DOWN
key to modify the setpoint.
3) Push
SET
to confirm or wait the timeout (15seconds).
Show the active SetPoint during Energy Saving or Dynamic Setpoint
If the unit is running in chiller or HP, the Energy Saving or the Dinamic Setpoint activity is signalled by the
blinking led of the SET button.
Chiller mode:
push
SET
one time, the bottom display shows the
SEtC
(set chiller) while the top display
shows the set value. Only if the Energy saving or the Dynamic Setpoint are active, pushing another time the
SET
key, the bottom display shows
“SEtr”
(real setpoint), and the top display shows the setpoint that the
unit is really using for the thermoregulation.
Chiller mode:
push
SET
one time, the bottom display shows the
SEtH
(set Heat pump) while the top display
shows the set value. Only if the Energy saving or the Dynamic Setpoint are active, pushing another time the
SET
key, the bottom display shows
“SEtr”
(real setpoint), and the top diplay shows the setpoint that the unit
is really using for the thermoregulation.
ATTENTION
The
SEtr
label appears only if the Energy saving or the Dynamic Setpoint are active.
To modify the working setpoint it is necessary the setpoint values is displayed on both the display
(temperature / temperature or temperature / pressure o pressure/ pressure) without any identification label,
otherwise the SET key swaps to the circuit information.
Display in Remote Off
From digital input configured as remote ON/OFF: the active input sets the unit in OFF (even when the unit is
a ).
The top display shows
“OFF
”, the led of the decimal point is blinking.
Display in Condensing unit configuration
The top display shows “ON” for active input and “OFF” for not active input. If the unit is running in Chiller the
top display shows
OnC
otherwise
OnH
for heat pump.
The configuration for condensing unit, as for chiller or HP, allows to show through the top and the bottom
display all the detected input measurements and alarms.
