MICROPROCESSOR TEMPERATURE CONTROLLER RT-08G  is a controller of the heating system, in which the heat source is the water jacket stove whose operation is controlled by the air damper controlling the combustion process. The primary function of the controller is to maintain the temperature in the water jacket at a preset level. That is carried out by the corresponding opening of the air damper that supplies air to the combustion chamber depending on the temperature measured in the water jacket. One of the basic functions of the controller is also maintaining a fully automatic operation of the 2 CH circulating pumps and the HW load pump whose work is regulated by temperature measurements made by two sensors in the HW  hot water storage tank.
