TMA2-3

This controller is suitable for voltage controllable 1-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.

After a power failure, the controller must be reset by turning the switch to the off position.

A branch transformer determines the voltage in each position. It is important to check whether the motor (fan) can be regulated by voltage.

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