The RCM Room Command Module is designed for use with LonMark compliant space comfort
controllers such as the TCU fan coil unit and VMA variable air volume box controllers from Johnson
Controls. A keypad and LCD display on the front of the module allow the room occupant to view and
change the operating parameters of the connected controller, including the space temperature
setpoint and fan speed. The occupant can also request the temporary occupied (bypass) mode
during unoccupied or standby periods, and the current operating mode is shown by a green LED
indicator and on the LCD display. The RCM connects directly to the LonWorks network and complies with the LonMark interoperability guidelines for sharing data with other LonMark compliant network devices. It is available with FTT-10 free topology transceivers or LPT link power transceivers, for a twisted-pair physical network configuration.
