- Page 3 1. Application. Controller RK-2001TW4 is intended for temperature control in the solid fuel fired water boilers. The boiler temperature is maintained at the level programmed by the user with blower rotational speed control. The temperature of the boiler water is monitored continuously by the regulator and shown on the display as well as the unit controls the central heating circulation pump.
- Page 4 Picture 1. Front panel of the RK-2001TW4 controller. The basic operation of the regulator depends on setting the desired temperature with the thermostat knob; the remaining functions are carried out according to the programmed parameters of the service mode. The change of thermostat parameters is shown on the display for a few seconds, e.g.

If it is not our intention to change the parameter value with the < or > buttons, then select [End ] and press the OK button or wait about 1 minute – the regulator will leave the service mode and the temperature of the boiler water will be shown.

When the „Πr” parameter is set to ‘0-10’, then this is the maximum capacity that can be obtained while automatic regulation. Minimum capacity of the blower [n 40] – is the minimum value of capacity at which the blower can work while the automatic regulation of rotational speed and gradual increase of rotations during ignition are on.
- Page 8 5.2. Central heating circulation pump working parameters. Temperature of central heating pump turn-on. [P 42] – is the value of the boiler water temperature at which the central heating circulation pump is turned on. The pump works regardless of the regulation process. Additionally, it is turned on in case of boiler overheating.
- Page 9 Boiler maximum temperature [H 85] – is the maximum value of temperature that can be set with the thermostat knob. Hysteresis of boiler temperature [h 2] – determines by how many degrees the temperature of the boiler water must be decreased from the programmed with thermostat so that the blower should be turned on.
- Page 10 option is useful in the heating systems where the solid fuel fired boiler is included in order to decrease the costs of heating. After the fuel demand alarm has been cancelled with the STOP button, the additional boiler is turned off again and the work of the regulator is resumed.
- Page 11 6. Additional options. To make the user feel more comfortable in the heated rooms, the regulator has been equipped with the input that enables to connect any household thermostat provided with a contact output. If the temperature in the room is lower than the desired one, the turning on the central heating circulation pump and the household thermostat light indicator will occur which means the temperature programmed with the thermostat knob should be maintained by the boiler.
