Single-phase transformer, where the fan speed is controlled by the supply voltage can be varied in five fixed stages, which are controlled manually with the aid of the changeover knob at the front.
Built-in thermo-contact motor protection (TK) breaks the supply voltage in the event of broken thermal contacts. Reset by turning the knob is turned to "0" position for about 10 seconds after the restart.
Input for room thermostat, RT, which in the event of contact break, cuts off supply voltage to the fan. Supplied with strap.
The transformer output 230V for control of the damper, electric battery or other external equipment. When the transformer is set to 0 or when the TK input is broken, the voltage is switched off.
The signal lamp on the front indicates operation. The fuse is reset from outside. RTRE has a cover made from self-extinguishing thermoplastic. Supply voltage: 230 V 50/60 Hz

Damper Engine - Belimo LF24
Art. no.: 6631424
Used to control the smaller dampers in the event of a power failure to the open or closed position. When connecting the power supply run the engine in operating mode, at the same time as the consumption spring is powered. If the supply voltage is broken the stored spring energy is triggered which returns the damper motor to its safety position.
Easy installation on the damper spindle with the universal clamp. The power unit is prevented from rotating with the aid of the supplied turning safety device.
The turning angle is adjustable with a built-in mechanical stop. High reliability performance
The engine is overload-proof, does not need any end position switches and stops automatically when the set stop position is reached.
