 The thermostatic unit controls a fan and a heating system circulation pump. An amount of air inflow into the boiler is regulated, whereas the draught regulator FR124 adjusts an air intake aperture lid. After the set up water temperature is reached, the fan is turned off by an operational thermostat of the boiler. During the whole boiler operation time a rotational speed of the fan remains constant. In the 0...60°C switch position the fan works permanently. In the central position the fan is switched off. In the beginning of firing, after the boiler has reached 60°C temperature, the switch must be turned to the 60...90°C position, then the fan will be turned off automatically after firing goes down.

 An aditional thermostat activates the heating system circulation pump, when the supply water temperature reaches 60°C, and turns off, when the temperature drops bellow 60°C.
