Page 3: Operation
1. Application. RK-2001W controller is a controller designed for temperature control of solid fuel fired boilers. The temperature of the boiler is kept on level set by the user by controlling the speed of the blow-in fan. The controller constantly monitors the temperature of water in the boiler, displays it on the display and controlls the central heating pump. - Page 4 Picture 1. Front plate of the RK-2001W controller Basic operation of the controller is carried out by setting the desired temperature with boiler thermostat knob, other functions are carried out according to parameters programmed in service mode. The change in the boiler temperature setting is displayed on the display for a few seconds, e.g.

- Page 7 5.1. Fan work parameters. Fan power [Π100] - this value defines power of the fan. When „Πr” parameter is set to „0-10” this is the maximum power of the fan which can be achieved during automatic fan control. Minimum fan power [n 40] - lowest fan power which can be used when automatic fan speed control is on and when fan speed is gradually increased during boiler start.
- Page 8 5.3. Preparation of hot tap water. The controller has additional output allowing to control the hot water tank loading pump by the UM (UM-1). The hot water tank temperature [u 50] – temperature value which will be kept in the hot water tank.

No-fuel testing time during fuel firing start [Fd2h] - after switching to WORK mode, if water temperature does not increase by 2°C in programmed time, the control process will be turned off and the display will show the message: [FUEL]. You can return to previous mode by pressing STOP button.

5.8. Factory defaults. Return to standard settings set by the producer by choosing [Prod] and pressing OK button. After activating this function, the controller sets each parameter showed in the table 2. 5.9. Testing outputs. To make checking the controller work easier, it is possible to test output circuits which control the fan and the pump, and the circuit which controls additional equipment. -

7. Controller failures. The controller is constantly testing if its internal circuits and temperature sensor are working correctly. After detection of fault, it stops the fan, turns on the central heating pump and shows proper error message on the display. In case of failure please turn off the controller, plug the central heating pump to the power source, ensure appropriate fuel firing in the boiler and contact the service. - Page 12 Picture 2.
