Manual five-step transformer (with motor protection) for RVK 315Y4, KTEX, DKEX and DVEX fans.

A three-phase transformer which controls the fan speed by altering the supply voltage in five fixed steps. The steps are adjusted manually, using the control knob on the front of the unit.
An integral motor protection device is included which cuts the supply voltage to the fan if the thermistor motor protection triggs.
The unit is reset by turning the knob to 0 for 1 minute. Input terminals for room thermostat RT cut supply voltage to the fan when the circuit is broken.

NB. The transformer can not be placed in the EX zone.
