4. TECHNICAL CHARACTERISTICS AND DESCRIPTION
4.1 Technical characteristics of boilers are shown in Table 1.
4.2 The boiler operates reliably throughout its service life in compliance with the operating conditions set out in this Manual
and timely maintenance.
4.3 The boiler device is shown in Figures 1, 2.
4.4 The coolant is heated in the heat exchanger flask. The number of heating elements and their power depends on the
boiler model (see Table 1). To extend the service life of heating elements, alternating switching on of heating elements
(rotation of heating elements) is provided.
4.5 Operation of the boiler is provided by the control unit.
The control unit controls the following parameters:
► value of coolant temperature at the boiler outlet;
the value of the air temperature in the room where the temperature sensor is installed (supplied);
temperature values in the DHW indirect heating boiler (if connected);
► condition of the room thermostat (if connected, the thermostat is not included). The boiler maintains the air
temperature in the room according to the value set by the room thermostat;
► coolant flow in the boiler;
► input status of the "Priority Consumer" function;
► the amount of leakage current;
► the magnitude of the input voltage.
Also manages the work:
► circulating pump;
► heating elements;
► DHW three-way valve (not included).
4.6 A manometer is installed in the boiler to visually monitor the working pressure. The operating pressure range of 0.4 ...
1.5 bar is highlighted in blue on the manometer.
4.7 For safe and reliable operation, the boiler is equipped with protective mechanisms and safety devices that provide:
►Boiler protection against overpressure - the boiler has a safety valve to protect against overpressure. If the pressure
value exceeds 3 bar, the coolant is automatically discharged.
►Overheat protection - in case of coolant overheating in the heat exchanger bulb, the emergency thermostat
switches off the boiler power supply and, accordingly, the heating elements, regardless of the presence of a switching
signal from the control unit.
►- the boiler is equipped with a flow sensor. If the flow
of water through the boiler is reduced to less than 3.7 l / min, the heating is automatically switched off and an error
code appears on the boiler display.
►Protection against high voltage;
►Leakage current protection.
