SAUTER RDT300 Flexotron 300 DDC HVAC Controller
01Product Identification
SAUTER RDT300 is a flexotron 300 DDC controller for HVAC control applications. Current manufacturer documentation identifies the full variant as RDT300F001, while SAUTER documentation for the RDB300 remote operating unit confirms the RDT300 controller interface, setpoint and operating-mode functions, system-status display, outside-temperature display, and time setting.
Match the complete model, ratings, ordered variant, installed system, connections, and protection requirements before ordering.
02Key Features
- DDC controller identified by SAUTER for HVAC control use.
- Supports the RDB300 remote operating unit.
- Remote setpoint changes and operating-mode selection are documented.
- Presence and absence changeover can be performed from the remote operating unit.
- System status and outside temperature can be presented remotely.
- RDT300 time information can be displayed and set through RDB300.

- Confirm the installed application program, sensors, actuators, terminal wiring, power supply, remote unit, and time settings before replacement.
Verified Identity
Model: RDT300
Type: Flexotron 300 DDC HVAC Controller
Manufacturer: SAUTER
05Applications
- HVAC control installations built around the SAUTER flexotron 300 controller.
- Systems requiring remote setpoint and operating-mode changes.
- Heating and cooling plant control with remote status, outside-temperature, and time information.
- Maintenance replacement in an existing RDT300F001 application after the installed program and wiring are documented.
06Lifecycle
- Use RDT300F001 as the verified full variant when checking availability, while retaining RDT300 as the submitted model reference.
- Back up or document the installed HVAC application, setpoints, operating modes, weekly timing, sensor inputs, and output functions before service.
- Confirm RDB300 compatibility and the four-conductor link when the installation uses remote operation.
- Do not migrate to another flexotron generation from the model name alone; I/O, programming, power, dimensions, and communication must be reviewed.
- After replacement, test every connected sensor, actuator, safety interlock, operating mode, remote command, and time function.
