The fan speed is regulated in five stages with the switch on the front. Signal light on the front indicates operation. If several fans are connected, the sum of the motors' maximum currents must not exceed the rated current of the transformer. Voltage output 230 VAC for e.g. operation indication or damper motor. Automatic restart after power failure. The transformer is fitted with a fuse on the secondary side. Motors equipped with an extended thermal contact must be connected to separate thermal contact motor protection.
