AP8. TEMPERATURE MODE
This section explains how to configure the
“TEMPERATURE”
control mode. This mode allows the drive to regulate the
speed of the ventilator as well as the warm or cold air inlet through a frequency inverter VSD*/A depending on the
temperature detected by the analogic sensor. Inverter starting is done from an external control (selector).
8.1 PROGRAMMING
Use the next table to change to, or modify, the TEMPERATURE mode.
Table “TEMPERATURE”
1. In order to make the regulation more dynamic, change the
 
o
 
parameters. Increase

until the output
is fast enough. The increase
 
as much as possible and stop before the system oscillates.
2. If we need warm air inlet we should configure

to 0, on the contrary, if we need cold air inlet we should
configure to 1 .
3. See sections 8.2 and 8.3 for the setpoint configuration.
8.2 PROBE SI-TEMP IND CONFIGURATION
Is recommended to adjust the output signal to 0-10V and the sensor SI-TEMP IND measuring scale. This adjustment by
means of the jumpers JP1 and JP2 respectively. Remove the cover of the probe to find this jumpers. ( See Fig. 15).

ATTENTION:
If there’s a power loss while the ventilator is working and the RUN switch is
closed, the drive will enter the stop stage and show

on the display. Once the power is
restored, if the RUN switch is still closed, the drive will maintain the stop status. In order to start
again, the RUN switch must be opened and closed again. This operation can be modified
setting the

mode in the

parameter.
