English The RWF50 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.
