Page 3: Operation
1. Application. RK-2001E2 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 1] – 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.

Page 8: Additional Functions
5. Additional functions. In order to improve comfort in heated rooms the controller is equipped with indoor temperature sensor connection. RK-2001E2 compares measured room temperature with value set with room thermostat knob. When the temperature is lower than desired temperature circulation pump is turned on and room thermostat indicator is lit, which means that boiler should keep temperature set with boiler thermostat knob. -
Page 9: Device Failures
Warning! If neither contact thermostat nor indoor temperature sensor is used, the connection should be short-circuited. 6. Device failures. The controller is constantly testing if its internal circuits and temperature sensor are working correctly. After detection of fault, it stops the pressure fan, turns on the circulating pump and shows proper error message on the display. - Page 10 Picture 2. RK-2001E2 connection scheme Picture 3.
