TMA3-21

630.210

This controller is suitable for voltage controllable 3-phase motors and can be operated manually, with the switch on the enclosure, or controlled automatically with the T55 thermostat or potential-free contacts of, for example, a climate computer.

In the "hand" position, the voltage of the fans can be adjusted (speed 0 to 5).

In the "auto" position, the thermostat can be set to the desired temperature. From the set temperature, the required fan speed (speed 1 to 5) will be applied depending on the ambient temperature.

The thermostat can be placed at a distance from the controller.

The controller will malfunction after:

  • thermal overload of the motor (fan)
  • thermal overload of the safeguard of the transformer
  • after a power failure

Reset the controller by turning the switch to 0 (off).

A tap transformer determines the voltage in each position.

Verify whether the motor (fan) is voltage-adjustable.
