1. GENERAL DESCRIPTION
The
1-channel switching receiver RCM 255
is a RF receiver designed to switch various
120V electronic loads such as incandescent lamps, high-voltage halogen lamps, electronic
ballast and inductive loads upon receipt of authenticated radio packets sent by EnOcean
transmitters. An EnOcean transmitter can simultaneously control an unlimited number of
receivers. Each transmitter has its own fixed 32-bit address. The RCM 255 ‘LEARNS’ the
address of transmitters that are assigned to the receiver.
1.1 Basic Functionalities
Each RCM 255 can operate as either a Push Button Switch receiver (by LEARNING EnOcean
PTM Switches) or a Magnet Contact Receiver (by LEARNING EnOcean STM 250 magnet
contacts), but not a mix of devices. The RCM 255 can LEARN either a maximum of 30
EnOcean PTM’s or up to 2 EnOcean STM 250’s. The memory of the receiver is empty when
delivered. By assigning the first transmitter the operating mode (push button switch or
magnet contact) is defined. The operating mode can only be changed after deleting all learned
transmitters with the CLR button.
a) Mode
ROCKER SWITCH
: Each assigned transmitter can be used to change the
switching state of the receiver. It is possible to switch ON (button I) with one switch
and to switch OFF (button O) with another switch. When learning a radio switch with
2-rockers, only the rocker which has been pressed is learned by the receiver.
b) Mode
WINDOW CONTACT
: If at least one of the assigned window contacts is
open, the switching state of the receiver is ON. If both contacts are closed the state
is OFF. The window contacts transmit a ‘supervisory signal’ approx. every 15min. If
there has been no supervisory signal for more than 60 minutes, the RCM255
considers the contact closed.
