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. You can check this
value by pressing OK button. After pressing START button, the fan starts to work and
the control process begins. STOP button stops the fan, for example allowing to add
fuel to the boiler.
If the controller isn't in service mode, the display shows water temperature of the

[50ºC] – WORK mode
[50ºc] – keeping fire in WORK mode
