PRODUCT SPECIFICATIONS
Siemens RWF55.51A9 Compact Universal Modulating Burner Controllers For Controlling The Temperature Or Pressure In Oil/Gas Fired 
The RWF55.... is used mainly for controlling the temperature or pressure in oil- or gas-fired heating plants. If the relevant parameters are set, the RWF50 can be switched to cooling mode and then controls in reverse operation. The RWF50 and this Data Sheet are intended for use by OEMs which integrate the controllers in their products!
Use
The RWF55.... is used either as a 3-position controller without angular positioning feedback or a continuous controller with analog output depending on the version. An external switch can be used to change to a 2-position controller for controlling 2-stage burners. The integrated thermostat function switches the burner on and off.
LED symbols on the front indicate the following operating states:
- Burner release
- Control pulses OPEN or CLOSED for driving the burner's air damper when using a modulating burner control, or stage I / stage II when using 2-stage burner control
- 2-stage operation
During operation, the digital displays above the keys shows the setpoint (green), the actual value (red) and - when making parameter settings - the relevant parameters.
Function
The following functions are included in the RWF55....:
- Digital PID controller with a 3-position or analog output of the calculated output level
- The controller can be switched to a 2-position controller for controlling 2-stage burners
- Automatic thermostat (or pressure controller) function in low-fire operation
- Minimum limiter and maximum limiter for the boiler
temperature or boiler pressure
- Manual operating mode
- Self-setting function
- Parameterization and visualization via USB interface and PC software ACS411
- Ramp functions (cold start/thermal shock protection)
- Heating/cooling
