      The RWF55 is used primarily for the control of temperature or pressure in oil- or gasfired heating plants. Depending on the setting, it is employed as a compact 3-position controller or as a modulating controller with an analog output. An external switch is provided to convert it to a 2-position controller for controlling 2-stage burners. The builtin thermostat function switches the burner on and off.
