3.1) Structure of the boiler:
Logica is typical solid fuel boiler with upper-down heating burning process. Digital
controller and fan provides comfortable using and perfect temp. regulation.
Unique air injection system ("common-air") to combustion chamber ensure excellent
burning process with low flue gases emission.
These feature also giving possibility of burning even bad quality of fuel. At the back side of
combustion chamber is installed mechanical movement cast iron grill.
3.2) Special features of Lo ica:
1. Full automatic burning process
2. Controller with room thermostat
3. 14 nozzles deliver fresh air on temp. request to combustion chamber
4. Overheating protection system (STB)
5. Connection to central heating pump.
6. Wide program settings depended on different fuel.
7. Big revisions door to cleaning.
8. Movement mechanical cast iron grill
9. Wide range of power: 17 - 465kW (on special request).
Structure of the boiler – logica 17-38kW – lower and upper combustion.

 Controller:
-Application
RK-2001W controller is a device designed for temperature control of solid fuel fired
boilers. The temperature of the boiler is kept on level set by the user by controlling
the speed of the blow-in fan. The controller constantly monitors the temperature of
water in the boiler, shows it on the display and controls the central heating pump.
To enable more precise temperature control of heated rooms the controller has
been equipped with an input for room thermostat connection. The controller also
enables controlling of the hot water tank pump.
In case of no fuel, the controller has an option to turn on gas or oil boiler (additional
option).
-Connection
Before turning on the controller by master switch, connect controller, fan and the
central heating pump power leads to appropriate sockets in the rear of the
controller. The temperature sensor should be placed in a measurement hole in the
boiler.
CAUTION! Before plugging in the controller check if the wiring system is properly grounded and
if the terminal screws of the output connector are properly screwed.
CAUTION! A fan and a central heating pump of maximum power of 450W can be connected to
the controller.
CAUTION! As additional option you can connect the UM-1 module to the controller that allows
controlling the additional boiler or the mixing valve and the hot water loading pump. It is
necessary to protect the power supply of these devices with suitable cut-outs.
Outputs of the controller that are not used may remain unconnected.
-Operation
After turning the controller on all the elements of the display are lit for a while to
check if they are working properly. The controller, when power appears, returns to
its last state before turning off or power loss.
Front panel of the controller (Pic. 1) consists of:
1-Master switch
2-Display, indicating boiler temperature and parameters
3-Room thermostat indicator
4-Boiler thermostat knob
5-Central heating pump work indicator
