Page 3: Operation
1. Application. RK-2001AT2 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 75]) and this value means the temperature, which the controller will be trying to achieve.
- Page 5 5. Temperature viewing mode. To enter temperature viewing mode press OK. Entering this mode will be signaled by fast blinking of room thermostat indicator. Use < and > buttons to move between viewing different temperatures. To exit temperature viewing mode select [End ] option and press OK button or wait for 1 min.

- Page 7 6.1. Pressure 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 fanwhich 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 - mode [Pr 0] – continuous work. - mode [Pr 1] - pomp work depends on additional thermostat work mode. In [Fc 0] mode central heating pump is turned on when room temperature is too low (additional thermostat connection shorted or room temperature lower than temperature set with additional thermostat knob).
- Page 9 - mode [Fc 0] - means that room temperature sensor is connected to the additional sensor connection. RK-2001AT2 will compare measured room temperature with temperature set with additional thermostat knob. When room temperature is lower than the desired temperature, room thermostat indicator will be lit meaning that boiler should keep temperature set with boiler thermostat knob.
- Page 10 Maximum exhaust gas temperature hysteresis [Fh20] – this parameter describes how much exhaust gas temperature should drop in relation to maximum temperature for the controller to stop [Hot ] alarm and resume normal work. 6.7. Fuel shortage testing. If central heating installation is equipped with exhaust gas temperature sensor ([Fc 1]), then fuel shortage testing starts when exhaust gas temperature falls below temperature set with additional thermostat knob.

6.9. Testing of device's 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 boiler. By choosing [outP] on the display and pressing OK button you can turn on the circulating pump for a while, by choosing [outΠ] and pressing OK you can turn on the pressure fan and by choosing [outr] and pressing OK you can turn the additional boiler, the alarm signaling system or the mixing valve servo-motor on (if the additional module is... -
