Universal Controllers
The RWF40... is a universal digital boiler temperature / pressure controller with
functions designed specifically for the control of heat generating plant.
The RWF40... and this Data Sheet are intended for use by OEMs which integrate
the controller in their products!
Mechanical design
The controller is supplied complete with housing for flush panel mounting. The
RWF40... is matched to the controlled variable and the required setpoint range by making parameter settings. The control parameters can be set and optimized while the
burner is running. All settings are made with 4 buttons located on the unit front and are
directly displayed.
LEDs on the front indicate the following operating states:
- Control ON / OFF
- Positioning pulses ON or OFF for driving the burner´s air damper when using
modulating burner control, or stage I / stage II when using 2-stage burner control
- «2-stage» operating mode
- Position of the configurable contact «K6»
- Manual control ON / OFF
During operation, the digital display above the LEDs shows the setpoint (green), the
actual value (red) and – when making parameter settings – the relevant parameters.
