Product Overview
The Toshiba RBC-AC2 is a duty-share change-over control panel engineered for three indoor units operating in 2-run / 1-standby mode. Two units operate concurrently, with the third held in standby and automatically switched in when required. A built-in temperature high-limit stat triggers full system response and alarm if ambient temperature rises beyond the set threshold. The panel is ideal for installations where continuous operation, automatic fault change-over and high-limit protection are essential. Operation is controlled with a preset duty cycle of approximately 100 hours per grouping: units 1 + 2 run for 100 hours, then 1 + 3, then 2 + 3, and repeat. On detection of a fault in one duty unit, the panel activates the standby unit immediately, illuminates the fault indicator and closes the common fault contact. The digital thermostat monitors room or return air temperature; if
it exceeds the high-limit set point, all three units operate, the fault relay closes and the alarm sounds. Audible alarm can be muted via the panel front-face switch. The panel also integrates with the fire alarm circuit to shutdown units in the event of a fire. Key Product Features: 2 Run / 1 Standby configuration: Two units active, one standby, rotating duty cycle for balanced usage. Automatic change-over on unit fault: Maintains system continuity with common fault relay output. Temperature high-limit stat monitoring: Activates all units and alarm if set limit exceeded.

Panel live, alarm, fire alarm, duty and fault indicators: Provides full visual status of each unit. Fire-alarm input: Allows automatic shutdown on fire-alarm activation. Digital
thermostat display: Shows room or return air temperature for monitoring. Mute-switchable audible alarm: For high-limit or fault conditions. Door-interlocked isolator: Safe access panel design.
