English Depending on the setting, the Siemens RWF55 universal controller is used as a compact 3-point step controller without position feedback or as a continuous controller with analog output. It can be switched to a 2-point controller for controlling 2-stage burners using an external switch. The built-in thermostat function switches the burner on and off. LED symbols on the front indicate the following operating states:
• Burner enable
• Control pulses OPEN or CLOSE for driving the burner air damper with modulating burner control or stage 1/stage 2 with 2-stage burner control
• 2-stage operating mode
• Position of the programmable contact K6
• Activation of a ramp function
• Communication via USB, Modbus, or Profibus
During operation, the digital displays above the buttons show the setpoint (green) and the actual value (red) as factory settings, and the respective parameters during adjustment.
Mains voltage; mains frequency:
AC 100…240V +/- 10%; 48…63 Hz +/- 10%
