- Page 3 1. Application. Controller RK-2001W4 is a device designed for temperature control in solid fuel fired boilers equipped with: - blower, - central heating pump, - domestic hot water pump, mixing pump or a pump charging the accumulative tank (optional), - household thermostat or exhaust gases temperature sensor (optional), - signalling device or an additional boiler (optional).
- Page 4 Picture 1. Front panel of the RK-2001W4 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.
- Page 5 If the circulation system is equipped with the accumulative tank, the desired boiler water temperature equals the value set with the thermostat knob (3). If the heating system is equipped with the domestic hot water tank, the higher of two component temperatures is accepted as the desired boiler water temperature –...
- Page 6 3.3. System with the household thermostat operation. If the heating system is equipped with the household thermostat, the desired temperature of the boiler water depends on the status of its contacts (3.1.). As an addition the central heating pump work may, depending on the service settings, be influenced by the household thermostat.

It is possible to view the parameters with buttons marked with “+”, “-”. After the particular parameter has been selected, you can enter the changing mode of the given parameter by simply pressing the OK button –...
- Page 8 domestic hot water system or the accumulative tank only are supported by the regulator. If the additional pump is turned off or it works as the mixing pump, then there is no possibility of changing the WINTER/SUMMER mode (the parameter is not available).

- Page 10 6.1. Parameters of blower work. Blower maximum capacity [Π100] – is the maximum value of capacity at which the blower can operate. Blower minimum capacity [n 40] – is the minimum value of capacity at which the blower can work. Changing the rotational speed of the blower ratio [Πh 2] –...
- Page 11 6.2. Central heating circulation pump working parameters. Temperature of central heating pump turn-on. [P 40] – if the heating system is not equipped with the accumulative tank ([ur 0], [ur 2] or [ur 3]), then the parameter defines the level of the boiler water temperature at which the central heating pump can be turned on.
- Page 12 Similarly, the [ur 2] value indicates the work of the additional input and output in the domestic water heating mode. The difference depends on the hot water being prepared with no priority, which means the central heating circulation pump is not turned off while the domestic water tank is being topped up.
- Page 13 6.5. Preventing the boiler from overheating. The temperature of boiler overheating [A 99] – defines the value of temperature which, when exceeded, causes the regulator to activate the alarm of the boiler overheating. STB – the regulator is equipped with an additional, independent of the processor security against the overheating.
- Page 14 6.8. Setting the parameters regulating the exhaust gases temperature. The exhaust gases temperature/ the exhaust gases sensor turn-on [c ---] – the parameter determines by what temperature of the exhaust gases the blower rotational speed will be decreased. Setting the parameter to ‘---‘ will cause the sensor of the exhaust gases temperature to turn off.
- Page 15 6.11. Exiting the service mode. To exit the parameters setting mode, select [End] on the display and press the OK button. Also, if no buttons will be pressed for 1 minute, exiting the mode occurs. 7. Controller disassembly. When disassembly of controller is necessary, you need to: –...

Questions and answers
Oběhové čerpadlo zůstává stabilně zapnuté bez ohledu na teplotu oběhové vody.
The KEY RK-2001W4 circulation pump stays continuously on if it is intended to charge the accumulative tank. In this mode, the pump is turned on permanently, regardless of the circulation water temperature.
