The 3-channel receiver HT3E has been designed for secure and tamper-proof remote control. The connection between a transmitter (HT8S and HT5S) and the receiver is encrypted using the recognized AES128 method and includes a so-called "rolling code." This makes each transmitted packet to the receiver unique and non-repetitive. The learnable receiver allows for the operation of up to 32 different handheld transmitters, which can be programmed into the receiver with the push of a button. The three relay outputs with high switching capacity feature a changeover contact and can be set to either momentary or latching function.
