8.3 SETPOINT ADJUSMENT OF THE CO2 CONCENTRATION
The setpoint is adjusted in the
parameter. This parameter is shown as a percentage depending on the sensor SI-
TEMP IND scale chosen in JP2 it has a different temperature value in ºC

8.4 WIRING
Before the start of the programming, wire the L1-L2-L3 input phases when using three phase equipment and wire the
L1-L2/N input phases when using single phase equipment.
Once the
“TEMPERATURE”
control mode is selected, that is after introducing the parameters of the Temperature mode
table (section 8.1), wire the drive as seen in the picture.
(See Fig. 14)
. The RUN signal must be connected between the
terminals 1 & 2, and the switch is always closed, the drive will start automatically when given power. If the user wants to
stop the operation with a selector, timer, etc.… Set up a free potential contact in series between the terminals 1 & 2.
8.5 “TEMPERATURE” OPERATION MODE
1.
Close the RUN switch connected between the terminals 1 & 2 to start the drive. The display will not show
to
start cold or warm air inlet, depending of the parameter
configuration, until reaching the set point configured
in
.
2.
If the parameter
is set at 0 and the temperature exceeds the set point value configured in
,
the inverter
VSD*/A will decrease the speed in order to keep it on the configured value. On the contrary, if the temperature
decreases below the set point configured in
,
the inverter VSD*/A will increase the speed in order to keep it
on the configured value.
3.
If the parameter
is set at 1 and the temperature exceeds the set point value configured in
,
the inverter
VSD*/A will increase the speed in order to keep it on the configured value. On the contrary, if the temperature
decreases below the set point configured in
,
the inverter VSD*/A will decrease the speed in order to keep it
on the configured value.
4.
If the user wants the drive to be always working, short-circuit the terminals 1 & 2 with a copper wire.
5.
If the
parameter has a value >0.0s, the drive will disconnect automatically. In this way, even keeping the run
connection, if the temperature is the desired, the inverter will stop and will show
in the display, starting
again when is necessary according to the set point value configured in
.
While the drive is ON, the user can see the motor consume pressing the Navigator key
>2 seconds.
