12e) Mode E: DIFFERENTIAL TEMPERATURE
In this mode, inverter ensures a differential temperature in the system. This operation mode requires either a
differential temperature sensor or two temperature sensors of same temperature ratings.
Caution: Use correct type of temperature sensor depending on the application.
Note: For temperature control mode, proportional and integral control setting may have to be adjusted according
to the distance between the temperature sensor and the heat exchanger.
In this point, the user can select whether they have 1 differential temperature sensor or 2 independent temperature
sensors. Use the arrow keys to select Option A or Option B.
By pressing the F2 button we select the option.

F2
We can select how we want the frequency inverter to behave based on
F

the detected temperature, that is, if the temperature increases and we
set the PI direction to positive, the motor will decelerate.
A

On the other hand, if the temperature increases and we set the value
to negative, the motor will accelerate.

temperature sensor reaches its minimum value (4mA).
By pressing the F2 button we set the value.
