Page 3: Operation
1. Application. RK-2001U controller is a device designed for temperature control of solid fuel fired boilers. The temperature of the boiler is kept on level set by user, by controlling the speed of the pressure fan. The controller monitors temperature of water in the boiler, displays it on the display, and controlls circulating pump. - Page 4 Picture 1. Front of the device. Basic operation of the device is done by setting desired temperature with boiler thermostat knob, other functions are realized according to parameters programmed in service mode. While changing boiler temperature settings with the knob, the change is displayed on the display for a few seconds (for example [C 55]) and this value means the temperature, which the controller will be trying to achieve.

Further increase of boiler temperature will cause fan speed to be reduced gradually to its minimum power [n 40]. Automatic fan speed control [Πr 0] – it is on, when this parameteris set to „0-10” and causes automatic fan speed decrease whentemperature of water in the boiler reaches desired temperature.If this parameter is set to „-”, the fan automatic smooth speedcontrol is disabled and the fan can work with power set by „Π”...

Boiler overheating temperature [A 99] – value, exceeding which causes permanent turn off of the pressure fan and launch of the circulating pump, to prevent boiler overheating. Overheating mode is indicated by boiler overheating indicator and by displaying error [E 2] on the display.

[Ar 2] mode – output may control mixing valve servo-motor. Controlling the mixing valve requires room thermostat to be connected to the controller. The mixing valve is being opened and closed depending on the room thermostat input. Additionally, mixing valve is opened in case of overheating or boiler temperature sensor malfunction.

circulating pump and shows proper error message on the display. In case of failure please turn off the controller, plug the circulating pump to the power source, bypassing the controller, ensure appropriate fuel firing in the boiler and contact the service. When [E 1] error appears on the display, it means fault (short-circuit) in the boiler sensor circuit or temperature below -9°C. - Page 10 Picture 2. RK-2001U connection scheme. Picture 3.
