The Compat sliding operator is an old model of the Italian company BFT. Several of the spare parts continue to be available. The Compat sliding motor was delivered with two different types of external gears: Gear with pin, that is, at the top of pinion there is a hole and locks onto the shaft with a pin. The later version is a straight pinion that secures on shaft securely (as shown in the separate diagram). Also, depending on the gear, there is different codes of reduction kits.
The new compatible control unit is ALPHA. The new ALPHA board is equipped with a Clonix 433mhz receiver and the old TM controllers are not compatible.
