USER’S MANUAL
3.1. Control Panel
The main control element of the boiler is the electronic board which controls all boiler’s operation. The
electronic board’s microprocessor collects and processes signals from the control and safety sensors. All
information about the boiler’s condition is displayed on the LCD display in real-time operation mode.
All control over the boiler is effectuated from the control panel, the appearance of which is shown on
Scheme 3.
If a remote control is connected to the boiler, then control is effectuated from it, the buttons of the control panel
are inactive.
In the left part of the control panel there is a pressure gauge, indicating the pressure inside the heating circuit.
Heat carrier pressure in the CHmust be not lower than 1 bar (with pressure lower than 0,5 bar the safety system
will be switched on and it would be impossible to put the boiler into operation).
In the center of the control panel there is an LCD display, showing the temperature in currently active mode at
normal operation of the boiler (at operation in the heating mode it shows the heat carrier temperature in the
heating system by the outlet from the boiler, at operation in the DHW mode –the DHW temperature by the
outlet from the boiler). In case of failure the error code appears on the display instead of temperature. The
boiler’s error codes are represented in the p.14.1 (page 34).
The symbols on display show the boiler’s operation mode. Around the display there are 6 boiler control
buttons. The designation of the control buttons and of the symbols shown on display are represented in the
tables 2 and 3 respectively.
3.2. Boiler operation modes
The boiler can operate in the following modes:
-
Standby mode (see p. 3.2.1);
-
DHW mode (see p. 3.2.2);
- combined mode (see p. 3.2.3, page 10);
- heating mode (see p. 3.2.4, page 10);
When the boiler is connected to the power line, it automatically sets up to the mode in which it was before
being switched off from the power line. Change of boiler’s operating modes is effectuated by pressing the K5
button on the boiler’s control panel (see p. 3.1, page 8). The sequence of the boiler’s operating modes change is
represented on Scheme 4.
