Manual five-step transformer (with motor protection)

The R-ET 14KTG is a single-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 thermal contact in the fan motor is activated. The unit is reset after cooling of motor, also by switch on main voltage.

The unit has input terminals for room thermostat RT, which stops the supply voltage to the fan when the circuit is broken. These terminals are linked before delivery. The transformer has 230V terminals for operating dampers, electric water-heater batteries or other external equipment. These terminals have no current when the transformer knob is in position 0, or when the TK or RT input is open. The indicator lamp on the front shows when the transformer is in operation. The fuse may be reset from outside. The top of casing is consist by ABS plastic (RAL7035), bottom part consists of aluminum. Supply voltage: 230V 50/60Hz.
