Description
The Johnson Controls TC-9102-0220 regulates fan coil units equipped with heating and cooling and a single-speed, 3-speed, or variable-speed fan. It drives water valves, one- or two-stage electric heating, or a cooling unit whose compressor carries its own short-cycle protection. A window contact switches the controller off, with low-temperature limit protection available.
Communication runs over an opto-isolated RS-485 N2 bus at 9600 baud, with a TM-9180 interface at 600 baud. It accepts a 24 VAC supply drawing 3 VA, and control inputs include a window contact, occupancy sensor, NTC room sensor, and remote set point. The unit mounts on DIN rail or surface at IP30.
